Cryptocurrency is a non-legal monetary asset based on digital technology and blockchain, possessing the functions of a medium of exchange and a store of value. Cryptocurrency is a transaction medium that uses cryptographic principles to ensure transaction security and control the creation of transaction units. Cryptocurrency is a type of digital currency (or virtual currency). Bitcoin became the first decentralized cryptocurrency in 2009, after which the term “cryptocurrency” was more commonly used to refer to such designs. Since then, several similar cryptocurrencies have been created, and they are usually referred to as altcoins. Cryptocurrency is based on a decentralized consensus mechanism, in contrast to the banking financial system that relies on a centralized regulatory system.

What Does USDT Mean? This Article Will Give You A Detailed Introduction To Tether

What does usdt mean?

USDT is the English abbreviation of Tether, a stable currency based on blockchain technology and issued by Tether. The following is a detailed introduction to USDT:

· Anchoring mechanism: USDT is anchored to the U.S. dollar, that is, 1 USDT ≈ 1 U.S. dollar. Its value is relatively stable with minimal fluctuations (usually within ±0.1%).

What does usdt mean_Introduction to Tether Coin_What does USDT mean

· Issuance principle: Tether claims that for every USDT issued, there will be an asset reserve of one US dollar. Customers can pay USD to Tether in exchange for an equivalent amount of USDT, or they can use USDT to exchange for an equivalent amount of USD to Tether. However, after Tether acquires funds by issuing USDT, it will retain a certain proportion of cash deposits to meet customers' withdrawal needs, and the rest will be used to purchase treasury bonds, bills, gold and other assets for reserves.

· Application scenarios

· Cryptocurrency trading medium: When the prices of cryptocurrencies such as Bitcoin and Ethereum fluctuate violently, users often convert their assets into USDT to avoid losses on currency holdings. In addition, more than 90% of cryptocurrency exchanges support USDT trading pairs. Users can indirectly buy and sell other niche cryptocurrencies through USDT without directly using legal currency to exchange, which lowers the transaction threshold.

· Cross-border payment and fund transfer: USDT transfer through the blockchain only takes a few minutes, and the handling fee is usually less than 1 US dollar. It is especially suitable for foreign trade practitioners and overseas workers to make small cross-border remittances. In some countries with strict foreign exchange controls, people can also use USDT to bypass the risk of local currency depreciation and achieve cross-border transfers of assets.

Introduction to Tether Coin_What does usdt mean_What does USDT mean

· Market size: As of the beginning of 2025, the market value of USDT is approximately US$157.6 billion, accounting for more than 60% of the total market value of global stablecoins. The average daily trading volume exceeds US$60 billion, far exceeding Bitcoin (average daily trading volume is approximately US$20 billion). It supports more than 500 exchanges and 2,000+ cryptocurrency projects, and more than 30 million users around the world use USDT.

· Potential risks: Due to the anonymity of USDT (blockchain addresses are not real-name) and global liquidity, it has been abused in scenarios such as money laundering and cross-border illegal fund transfers. In addition, USDT has caused a crisis of confidence because its reserve assets include non-cash assets such as commercial paper and corporate bonds (rather than 100% US dollar cash). If there is a large-scale redemption in the market in the future, it may trigger a "run" and lead to de-anchoring.

A brief introduction to Tether company! Tether is a stablecoin issuance company headquartered in El Salvador. It is operated by Bitfinex and its CEO is Paulo Ardoino.

Introduction to Tether Coin_What does usdt mean_What does USDT mean

In 2014, Realcoin, the predecessor of Tether, was founded by three co-founders: Brock Pierce, Reeve Collins and Craig Sellars. It was renamed Tether in November of the same year.

__LINK_ICON

. The Tether currency (USDT) issued by Tether is the world's first stable currency and can be exchanged with currencies such as the US dollar, euro, and offshore renminbi at a certain ratio.

__LINK_ICON

. The working principle is that users deposit fiat currency into a Tether account, Tether issues tokens and sends them to the user's wallet. The tokens can be used for transactions, etc. Users can also exchange the tokens for fiat currency, and Tether removes the tokens from circulation and returns the equivalent amount of fiat currency.

__LINK_ICON

What does USDT mean_Introduction to Tether Coin_What does usdt mean

As of the first quarter of 2025, Tether's total assets were US$149.3 billion, total liabilities were US$143.7 billion, and net equity was approximately US$5.6 billion.

__LINK_ICON

. In 2024, Tether's net profit reached US$13 billion, and it directly and indirectly held US$113 billion in US Treasury bonds. In July 2025, Tether also stated that it had nearly 80 tons of gold in Switzerland.

__LINK_ICON

Tether has also experienced some twists and turns during its development. For example, it suffered a hacker attack in 2017, was sued by the New York State Attorney General in 2019, and reached a settlement with the New York State Attorney General in 2021 and paid a fine of US$18.5 million.

1. Refuse private transactions: only trade in the OTC area of ​​the regular platform, and the platform's custody funds can prevent "payment without delivery".

2. Insist on real-name payment: use your own bank card/Alipay/WeChat transfer. It is prohibited to use third-party accounts to avoid fund freezing.

3. Be wary of abnormal prices: USDT price should be in the range of 6.9-7.3 yuan (fluctuating with the exchange rate). Merchants that deviate too much may be scams.

4. Do not click on external links: only communicate through the platform’s built-in chat system, and reject any external links and QR codes sent by merchants.

5. Keep transaction vouchers: Save transfer screenshots, order details, and chat records for at least 3 months for subsequent verification.

6. Avoid large high-frequency transactions: Newbies are advised to make a single purchase no more than 5,000 yuan to avoid triggering bank risk control.

7. Prevent "Black U": Give priority to the platform's "Quick Zone" or "Certified Merchants". The USDT sources of these merchants are safer.

8. Do not participate in buying on behalf of others: Any activity of "buying USDT on behalf of others and getting commission back" is a scam and may lead to loss of funds.

9. Transfer assets in a timely manner: It is not recommended to store large amounts of USDT in exchanges for a long time. It is safer to withdraw money to a personal wallet.

What Does USDT Mean? Introduction To Tether, A Virtual Currency Linked To The U.S. Dollar

What is USDT? The Chinese name of USDT is Tether. It is a virtual currency that links cryptocurrency to the legal currency US dollar, and serves as a stable currency.

USDT, the full name of Tether, is a cryptocurrency pegged to the US dollar, also known as a stable currency. Since its launch in 2014, USDT aims to provide a relatively stable trading medium and value storage tool for the digital currency market.

What is USDT_Introduction to Tether_What does USDT mean?

What does usdt mean?

Tether (USDT) is a token TetherUSD (hereinafter referred to as USDT) launched by Tether based on the stable value currency US dollar (USD). 1USDT=1 US dollar. Users can use USDT and USD for 1:1 exchange at any time. Tether strictly adheres to the 1:1 reserve guarantee, that is, for every USDT token issued, its bank account will have 1 US dollar of funds guaranteed. Users can conduct fund inquiries on the Tether platform to ensure transparency. However, this mode of operation of USDT has also caused some controversy. Some skeptics have expressed doubts about whether Tether has sufficient U.S. dollar reserves, and some have raised questions about the transparency of its audits.

Tether is a virtual currency that pegs the cryptocurrency to the U.S. dollar, the fiat currency. Each Tether is symbolically tied to a government-backed fiat currency. Tether is a virtual currency held in a foreign exchange reserve account and backed by legal currency. This method can effectively prevent large price fluctuations in cryptocurrency. Basically, one Tether is worth 1 US dollar.

The main role of USDT

USDT plays an important role in the cryptocurrency market, mainly in the following aspects:

1. Provide stability. Since USDT is pegged to the US dollar, its price is relatively stable. When cryptocurrency prices fluctuate violently, holding USDT can play a hedging role and help investors reduce risks.

2. Convenient trading medium As a stable currency, USDT can be easily used to purchase other cryptocurrencies without going through the cumbersome process of legal currency exchange. The transaction speed of USDT is faster and the handling fee is relatively low.

3. Increase market liquidity. As one of the most widely used stablecoins currently, USDT provides important liquidity support for the cryptocurrency market. Many exchanges support USDT trading pairs, and users can easily use USDT for currency transactions.

Detailed explanation of the role of USDT 1. Acting as a bridge and medium

The main role of USDT is to act as a bridge and intermediary in the cryptocurrency market, allowing users to convert and trade between cryptocurrencies or between cryptocurrencies and legal tender more conveniently, faster, and at lower cost.

For example, if a user wants to buy Bitcoin (BTC) with Chinese Yuan (CNY), he may need to go through the following steps:

This process can take a lot of time and fees, and also involves policy and regulatory risks.

If using USDT, users can simplify this process:

This process saves time and fees, and avoids the risks of using fiat currency directly.

In addition to being a conversion and trading tool, USDT also has the following functions:

2. Keep the value of virtual currency unchanged 1. Avoid the risk of overall decline

In currency-to-crypto transactions, there are three common situations, taking LTC/BTC transactions as an example:

After buying LTC with BTC, both BTC and LTC will rise, and you will enjoy two benefits;

After buying LTC with BTC, BTC and LTC will rise and fall one by one. Your income depends on the rise and fall of the two currencies, which one is greater. As long as the increase of any one is greater than the decrease of the other, you will make a profit. Anyway, it’s a loss. If the rise and fall are equal, there will be no profit or loss;

After buying LTC with BTC, in extreme market conditions, both currencies are falling, and you need to bear two losses. This is often the worst part.

But with USDT, when the currency price drops, you can immediately exchange the currency for USDT, thus ensuring that your assets do not shrink.

2. Reverse operation of digital currency withdrawal

Recharging is simple. The USDT company said investors can wire USD to Tether's bank account via SWIFT, or exchange for USDT through the Bitfinex exchange.

If you have made a lot of profits and want to withdraw cash, you can first exchange your coins for USDT, and then exchange them for US dollars through Tether or other platforms. Here you can find that if you complete the USDT company's certification, you can directly trade on other currency trading platforms that do not require certification, and there is no need to re-certify other platforms.

However, the withdrawal process is not that easy. You can return the USDT in your hand to Tether through Tether. The Tether company destroys the USDT received and issues equivalent US dollars to users. It should be reminded that whether you are buying USDT by wire transfer of US dollars to the bank account provided by Tether, or exchanging USDT back to US dollars, you need to complete account verification. It is understood that Tether's KYC is relatively difficult to pass, and the exchange fee is about 5%.

In addition, USDT can be exchanged for US dollars through trading platforms such as kraken. On the Kraken platform, select the USDT/USD trading pair to convert USDT to US dollars.

Why is USDT so controversial?

Although USDT has many advantages and functions, it also faces a lot of doubts and controversies. Mainly include the following aspects:

In summary, USDT is a cryptocurrency pegged to the U.S. dollar that plays an important role in the cryptocurrency market, providing convenience and value to users. However, USDT also has controversies and risks in terms of reserves, manipulation, and supervision, which require users to use and evaluate it carefully.

Risks faced by USDT

Although USDT has its advantages, there are also some risks worth paying attention to:

1. Issues of trust and transparency The stability of USDT relies heavily on the credibility of Tether and the adequacy of its US dollar reserves. However, the company has been criticized for its transparency and auditing practices, which has led to distrust among some users.

2. Regulatory risks At present, the regulatory policies of various countries on stable currencies are still unclear. If USDT is found to be in violation, it may face regulatory sanctions or use restrictions, which will have an impact on its circulation and use.

3. Market risk Although USDT is anchored to the US dollar, it still operates in the cryptocurrency environment. If the entire cryptocurrency market experiences significant fluctuations or declines, USDT may not be able to completely avoid losses.

in conclusion

USDT is an important stable currency in the cryptocurrency market, providing a trading medium and value scale for the market. It reduces the volatility risk of cryptocurrencies to a certain extent by being pegged to the U.S. dollar.

But at the same time, USDT is also facing problems such as trust crisis, regulatory uncertainty and market risk. In the future, whether USDT can further improve transparency and improve compliance will affect its development prospects to a certain extent.

Regardless, stablecoins still play an indispensable role in the current cryptocurrency market landscape. As a representative of this type of token, USDT’s development deserves continued attention.

Product Manager Tips And Tools: From Idea To Product Prototype

If a worker wants to do his job well, he must first sharpen his tools.

From idea to product, there are several twists and turns in between. The determination of product positioning determines the life and death of the product. The determination of product functional requirements determines the development cycle and the cost of trial and error. The Internet is all about speed, so it is necessary to make an MVP (minimum viable product). Of course, before that, you can also demonstrate the product through high-fidelity prototypes.

Let’s sort out some working methods and tools from product conception to project execution and product prototype delivery stages:

1. Idea

First, draw a user flow chart based on the product form, such as the registration and login process, and the shopping process of shopping APP users, which will help you think about the pages and functions involved in the product. Next, you need to classify and summarize the functions of the APP, and use a mind map to sort out the structural framework of the product, which will serve as a reference for designing the APP interface.

In the conception stage, it is OK to draw a sketch with a pencil. Once it is finalized, it needs to be organized into the PRD document.

Material organizing tools: Pixave, Ember, Inboard… Quickly build your material library by labeling and classifying pictures, and it is easy to search.

You may ask, "With a professional UI/UX designer, does a product need to be so in-depth about design?" On the one hand, I really love design, and I will devote all my energy to research; on the other hand, my point of view is that UI design is based on your prototype for interface design, which will be subject to certain limitations. If you are a more advanced designer, you will add your own experience and thinking to the design. The junior UI may be designed directly based on your prototype. You have more say in UI design such as color matching and icon drawing, but your product structure and layout affect the design ideas from the beginning.

3. Sketch

Paper and pen are the best tools, bar none, that can quickly draw the interface in your mind.

It is recommended to use dotted scratch paper with a mobile phone frame to facilitate controlling the size of elements according to their actual physical dimensions.

4. Design

At this stage, hand-drawn design drafts can be made into prototypes. The high-fidelity model can define a UI interaction design draft that includes colors and interface elements, or it can be defined as a relatively high-fidelity grayscale, colorless design that includes interaction logic. I think that for products, it is the latter. The product focuses more on the interaction between the interface and people and the logic between interfaces.

High fidelity can reduce communication costs, and the display of product logic, processes, layout, and operating status can quickly be understood by team members.

There are many tools for prototyping, such as Axure RP for Web, Justmind for mobile design, and online Ink Knife, etc.

Sketch is highly recommended here, a professional mobile APP interface design software, and the product can also be used for prototypes.

Sketch is a vector drawing app for all designers. Vector drawing is currently the best way to design web pages, icons and interfaces. But in addition to vector editing capabilities, we also added some basic bitmap tools, such as blur and color correction. We try our best to make Sketch easy to understand and use. Experienced designers can use their design skills in Sketch in a few hours. For most digital product designs, Sketch can replace Adobe Photoshop, Illustrator and Fireworks. ——Excerpted from "sketch User Manual"

Sketch provides native controls for iOS and Android systems, which can be used directly.

Those Techniques - Color Theory (translation Theory)

Remember the early days of your school days, when having a 64-count box of Crayola crayons was the ultimate in creative freedom?

Okay, so as a designer in the digital age, you certainly don’t have to work with paints, inks, or other pigments, although we can learn color from a fine art approach. In fact, the human eye can see millions of different colors – but sometimes, choosing, or even just 2 or three, to use from these millions can seem like a daunting task.

This is because choosing colors for design is very subjective and, sometimes, highly scientific. So, where are the designers who just want a color palette that looks good or makes the client happy? Like it or not, the most effective color choices are more than personal preference, as color has an extraordinary ability to influence mood, emotion, and perception; take on cultural and personal meaning; and attract attention, whether consciously or subconsciously.

For designers and marketers, the challenge is balancing these complex roles that color plays to create an attractive, effective design. This is where a basic understanding of color theory can come in handy. Traditional color theory can help you understand which colors work well together (or not) and what effects different combinations will have in a design.

It all starts with the color wheel.

Basics: Understanding Color

color wheel

You may have seen it in a school art class, or at least be familiar with it in its stripped-down form: the primary colors of red, yellow, and blue. We will deal with the 12 traditional colors often used by painters and other artists. This is a simple visual way to understand color relationships.

The basis of color theory_Behance Download for Android_Color psychology application

The color wheel is all about mixing colors. Mixing the primary colors, red, yellow and blue, you get the secondary colors of the color wheel: orange, green and violet. Combine those with a primary color and you get the third level of the color wheel, the tertiary color. These include red-orange, yellow-orange, chartreuse, blue-green, bluish-violet, and red-violet. The primary and secondary colors (with the additional blue) are part of the visible light spectrum, or the "colors of the rainbow," which many of you remember by the abbreviation "Roy. G BIV." As a child, remember these colors: red, orange, yellow, green, blue, indigo, and violet.

This way of understanding color is called a subtractive color model, which involves mixing color pigments in paints or inks – both traditional colors and printing equipment used fall within this category of the CMYK color system. This is opposed to the additive model, which involves mixing colored light (like the colors you see on your computer screen or TV) using a set of different primary colors: red, green, and blue, often abbreviated RGB.

In the survey we have our own version of the colors that you can choose. Any color you choose will be determined by a hexadecimal value (or hex code), a six-digit number and/or letter combination (usually preceded by #) used in many design schemes to determine specific colors when designing web pages.

The basis of color theory_Behance Download for Android_Color psychology application

color words

Before we get into how to use the color wheel to create a color palette for your designs, let’s look at some color-related terms that will help you understand the different types of colors you might use in your work on design projects:

Hue: A synonym for "color" or a specific color, traditionally referring to one of the 12 colors on the color wheel

Color: black color

Color: Dull gray

Color: bright white color

Saturation: refers to the intensity or purity of a color (closer to a hue, closer to gray, more saturated)

Value: refers to the lightness or darkness of a color

color harmony

Now that we've got the more technical stuff out of the way, let's look at how the color wheel can be a practical resource for choosing colors for design projects. We can think of some classic palettes as color wheels that painters have used for centuries to create balanced and visually pleasing (or high contrast and stunning) compositions. In most design applications, these color schemes need to be broken down into one dominant color, either because of how much it appears in the design, or because of how it compares to other colors – and one or more accent colors.

1) Monochrome: A variety of colors, tints, or tints of one color; for example, blues range from light to dark; this scheme is more subtle and conservative

2) Similar: Having a color on the color wheel, this type of scheme is versatile and easy to apply to design projects

3) Complementary: colors that are in opposite directions, like red/green or blue/orange; complementary colors are high contrast and high intensity, but can be difficult to apply in a balanced, harmonious way (especially in their purest form, when they can easily clash in a design)

4) Split Complementary: Two more flankers on the color wheel complement any color; this scheme still provides strong visual contrast, but is more harmonious than complementary color combinations

5) Three: Three, evenly spaced colors on the color wheel

6) Quad/Double Complementary: Two pairs of complementary colors; this scheme is very eye-catching, but may be more difficult to apply to a pair of complementary colors because the colors are more difficult to balance. If you use this type of plan, you'll want to choose one of four colors that are dominant and adjust the saturation/value/etc of some or all of the colors so they work well in different parts of the design, such as text and background.

color inspiration

In addition to the color combinations found in color combinations, nature offers endless inspiration for harmonious color schemes. For 25 great color palettes pulled from nature photography (and others inspired by travel, food and drink, and everyday items), check out another of our design school articles, “100 Gorgeous Color Combinations: How to Apply Them to Your Designs.”

Colors can also be paired with temperature (warm or cool colors), saturation (bright colors often look younger, while washed out looks), mood (bright and fun, dark and serious), theme (location, season, holiday), and other qualities. To explore different color schemes, check out one of the many color selection tools available online, some will even let you upload an image to generate a color scheme. Some attempts include paletton, Adobe CC (formerly known as Kuler Color), and colorexplorer. If you use a browser, you can download the Eyedropper extension, which allows you to identify and pull colors directly from the web.

The bright, cheerful color palette is inspired by exotic travel locations.

Finding color inspiration from different historical periods and art movements can be another great technique. The palette below shows the warm, light-filled colors common to Impressionist paintings; the vivid, unexpected combinations used by Post-Impressionist painters; the soft, earthy colors characteristic of Art Nouveau; and the bright, bold colors of Pop Art.

color psychology

The colors around us. Whether we realize it or not, it plays an important role in our daily lives. That orange or yellow traffic sign you see on the road? This gets your attention. Do you buy a box of cereal at the market, even if it is a little more expensive than others? You may have been drawn to the color of its packaging. Color even creeps into language in creepy ways… Why do we say people "see red" when they're angry or "blue" when they're sad? Because color has a unique connection to our moods and emotions.

But not everyone thinks or experiences color in the same direction. The meanings and symbolism of the cultural and social groups we identify with and the different colors we associate with them are greatly affected. Let’s take a look at the basic colors in Western culture:

color symbolism

Red: This color can convey many different ideas depending on the context. Because red is associated with fire, it can represent warmth or danger. Since red is also the color of blood, it is considered an energy, lively color and is also associated with heart problems and sometimes violence.

Alternative meanings: In some Eastern cultures, red symbolizes good luck and prosperity and is the color worn by brides on their wedding day. Across the world, red has been associated with various political movements and symbolizes revolution.

In terms of branding: Red often conveys power, confidence, and power, and is a very visible color.

Alternate meanings: In India, saffron, a certain shade of yellow-orange, is considered sacred. In Japan, orange is the color that symbolizes love.

Brand: Orange often represents youth and creativity. Gold, which is an orange or yellow color depending on its hue, is a symbol of luxury or high quality.

•Yellow: The color of sunlight, yellow often conveys happiness, joy, friendship, and the freshness of spring. It can also issue warnings or warnings in certain circumstances. Some variations (especially saturated yellows and greens) can look sick or unpleasant; historically, yellow was sometimes associated with disease quarantine.

Alternative meanings: In some Eastern and Asian cultures, yellow is associated with royalty or high status. In parts of Africa and Latin America, yellow is the traditional color of mourning.

On branding: Solid/bright yellow work attracts attention but can be visually disturbing and even difficult to see (e.g. a bright yellow background or vice versa) if not used with care.

Green: This is the color of nature, plant life, growth. As such, it often conveys healthy, fresh, or "all natural" qualities. Dark green can represent wealth (or anything money related) and stability.

Alternative meanings: In the culture that practices Islam, green is a sacred color. Green is also associated with Ireland and, by extension, St. Patrick's Day and the lucky four-leaf clover.

Brands or products that want to be "green" (in the sense of natural, healthy, sustainable, eco-friendly, organic, etc.) often use nature-inspired colors such as green and brown.

Dribbble/Anna Hurley

Blue: The color of the sea and sky, blue often conveys peaceful, clean qualities. And more energetic, warmer and cooler, blue is seen as calming. In some cases, it can represent sadness or depression.

Dribbble/DI

Alternative meanings: In Middle Eastern cultures, blue has traditionally represented protection from evil. Because of its association with heaven, blue symbolizes immortality and/or spirituality in many cultures.

In Branding: Blue is one of the most widely used and versatile colors. Generally used to communicate integrity, security and stability. Dark or deep blue is an especially popular choice because of its corporate background and because it is believed to have serious, conservative, professional qualities.

Purple/Purple: Purple is often associated with royalty, majesty, or honor. It can also have spiritual, mystical or religious connotations.

Alternative meanings: In many cultures around the world, purple represents nobility or wealth; however, in Thailand and southern America, the color is associated with mourning.

Brand: Darker shades of purple also often symbolize luxury and affluence, while lighter/brighter shades can come across as feminine or childish.

Black: Red, black has many (and sometimes opposing) meanings. It can represent power, luxury, sophistication, and exclusivity. On the other hand, it can symbolize death, evil, or mystery. In dress, black people generally wear either ceremonial ("black tie" for parties) or sad and sorrowful (as traditionally worn for funerals).

Alternative meanings: In some Asian and Latin American cultures, black is considered a masculine color. In Egypt, black represents rebirth. In many cultures, colors have magical powers, superstition, or bad luck, again, this is still unknown.

In terms of branding: black is so widely used that it’s almost a neutral, but it can still communicate more than its meaning depending on the context. Many designs are in black and white, either as a deliberate choice or simply to save money on color printing. Colors always look brighter and more strongly against black.

Dribbble/澾gjokaj

White: Due to the color of light and snow, white often represents purity, innocence, kindness, or perfection (and is traditionally worn by brides), but it can also be exactly as stark or sterile.

Alternative meaning: In China, white is the color of mourning. It represents peace in many cultures – a white flag is a universal symbol of truce or surrender.

In branding: White often conveys simplicity or clean, modern qualities. Designers seeking a minimalist aesthetic will often use lots of white.

color in design

Add a color scheme to your design rather than choosing two or three more shades to smash down in equal parts throughout your layout. Effectively applying color to a design project has a lot to do with balance and the colors you use, the more complicated it is to achieve balance.

An easy way to think about this concept is by splitting your color choices into dominant and accent colors. In your design, the dominant color will be the most obvious and most frequently used color, while one or more accent colors will complement and balance the main color. Paying attention to how the colors interact with each other in terms of contrast (or lack thereof), the readability of the text when it is referenced, how certain colors make others look when they are next to them, what kind of mood color combinations create, etc. – will help you fine-tune a perfect color palette for your design purposes.

Using a basic common rule of thumb in designing with three colors is called the 60-30-10 rule. This method is typically used in interior design, but can also be effectively applied to web or print design projects. You'll only make your dominant hue 60% of the color in the design, while bicolor colors use the remaining 30% and 10%. A good analogy to understand this piece is to depict a man's suit: the blazer and pants account for 60% of the outfit color; the shirt and tie account for 30%; provide a small pop of color at 10% – creating a balanced, polished look.

Another way to keep your palette simple and balanced is to use tints and tints (or dark versions of your chosen shades). This way, you can expand your color options without overwhelming your design with a rainbow of colors.

Dribbble/Seán Halpin

Color in marketing and branding

Brand identity is closely linked to color. Just think of Coca-Cola, Facebook, or Starbucks, and I bet you can immediately name the colors that those brands associate with.

A study by the University of Winnipeg, titled "The Impact of Color on Marketing," found that people's initial judgments about products are based on color (about 60 to 90% of evaluations – in just 90 seconds – are based on color). This means that in design, color is not only an artistic choice, but also an important business decision – influencing everything from consumer perceptions of a brand to product sales.

However, when choosing a color scheme for your logo or brand, you don't have to stick to any traditional symbols, or conventional methods. There are no foolproof processes or hard and fast rules when it comes to color. Most importantly, the color used in the design is a good fit for the brand's personality and market environment. For some inspiration, visit a website, brandcolors, that has compiled a visual guide (hex code) from well-known brand color choices from around the world.

RGB and CMYK color systems

When you are working on a design that will be printed, your computer monitor will not be able to display the colors accurately as they will be seen on paper. "What you see is not what you get," because digital monitors/screens and printers use two different color systems: RGB and CMYK. RGB refers to the small dots of red, green, and blue light that form visible colors on the screen; while CMYK represents the color printing created by mixing cyan, magenta, yellow, and black inks on printing equipment. Since the RGB color space uses other colors than CMYK, it is worth noting that some designers prefer to initially create print projects in RGB for more color options and then transfer the design into the finished product before printing in CMYK.

Download for Android_Color Psychology Application

Because of these differences, designers need a way to get consistent color results when working with both systems – for example, if you're designing a logo for your website but also want to get a business card printed. This is where the Pantone Color Matching System (or systems) can help. Colors can be matched to web and print (as well as different types of printing surfaces) to ensure a unified look. The Pantone system makes it easy for designers, clients, and printers to collaborate to ensure the final product looks as intended.

How Is The Price Fluctuation Of Tether Affected? An Article Explaining In Detail The Working Principle Behind USDT

Tether's main goal is to maintain a price of $1, but there have been several significant price fluctuations in history.

For example: In 2017, due to the Taiwan Bank incident, the price fell to $0.91. In 2018, it fell to $0.9 due to the US government investigation.

But it is worth noting that after these events, the price of Tether is usually able to return to levels close to $1 within a short period of time.

Fourth, factors affecting market confidence

Tether’s stability largely depends on the market’s confidence in it. For example, government regulation may affect this confidence. Once market participants become uneasy about the reserves behind Tether or how it operates, prices can be subject to volatility.

Although Tether has been in existence for nearly 10 years, many price changes have always returned to the value of 1 US dollar "within 2-3 weeks".

However, investors still need to pay attention to relevant risks and market changes and should not take it lightly.

Factors affecting Tether market confidence_What does USDT mean_Tether price fluctuations

The principle of Tether (USDT)

It is stated in the white paper on the official website: Each Tether coin is worth equal to 1 US dollar and is 100% backed by Tether reserves. That’s why we call it a “stablecoin.” But how does it work behind the scenes?

First, when you use 1 USD to buy Tether, Tether Limited will deposit the 1 USD into a specific bank account as a reserve. In contrast, when you exchange Tether for U.S. dollars, the company will withdraw the equivalent amount of U.S. dollars from its reserves and destroy the USDT. This ensures that the total amount of USDT issued is always consistent with the total amount of USD reserves.

In short, the company Tether Limited acts like a middleman, providing us with a "USD play currency" that can be used in the cryptocurrency world. This model is very popular among cryptocurrency exchanges, especially when market prices fluctuate violently, Tether provides a relatively stable value anchor.

However, there are still some doubts and doubts. Although Tether Limited has always emphasized that each Tether coin is backed by US$1, there are still doubts in the market about the authenticity and adequacy of its reserves. One of the key questions at the heart of this is: If everyone wants to convert USDT to USD, does the company really have enough cash to support it?

This incident also reminds us of an important concept: currency is valuable because people generally trust it. Now, the market recognizes the value of Tether, but if trust is damaged, the value of Tether will also be seriously affected.

Tether uses advanced blockchain technology, which not only provides transaction transparency, but also ensures security. In addition, with the advancement of technology, Tether has been implemented on different blockchain platforms, such as: Ethereum and TRON, which means that there are multiple versions of USDT.

What will happen if there are "multiple versions" of USDT? Tether (USDT) has multiple versions on different blockchain platforms, just like a popular game has its own versions on different gaming platforms. So what does the existence of these multiple versions mean to us?

First, the convenience of transactions. First of all, multiple versions of USDT mean that it can be circulated on different blockchain networks. For example: when a person uses an exchange based on Ethereum, he will use the USDT version based on Ethereum, and on an exchange on the TRON network, he will use the USDT version based on TRON. This increases the convenience of transactions and allows users to easily switch between different platforms.

Second, enhanced liquidity because USDT can operate on multiple blockchains, which enhances its market liquidity. No matter which platform you are on, you can find USDT, which makes it a cross-platform "universal game currency".

Third, we should pay attention to the exchange issues. However, this also brings some minor troubles. Different versions of USDT are not directly compatible with each other. If you have Ethereum-based USDT but want to use it on the TRON network, you may need to exchange it through a specific bridge service or exchange.

Fourth, multiple guarantees of security. Each blockchain platform has its unique security features. Multi-version USDT means that the security behind it is multiple and not entirely dependent on a single blockchain platform. This provides an additional layer of security to some extent.

What are the risks of Tether (USDT)?

As one of the most popular stablecoins, Tether has a wide range of applications in the market, but there are many risks and questions behind it.

Risk 1. Opacity of financial data

In 2021, Tether reached an agreement with the New York Prosecutor's Office and promised to disclose its guarantee information. However, judging from the data it provides, its reserve information has not been formally audited and confirmed, and detailed information is relatively lacking.

Real cash accounts for less than 4% of published margins, while the majority of reserves (about 65%) are classified as commercial paper. However, specific details of the commercial paper were not disclosed due to "commercial reasons." This is the first risk of Tether.

Risk 2. Doubts arising from reserves

According to data disclosed by Deltec Bank, in the first nine months of 2020, Tether's foreign currency increased by US$600 million, but its Tether issuance increased by US$5.4 billion during the same period, a gap of nearly 7 times.

Tether's other reserves, such as mortgage loans and investments in Bitcoin, are mostly assets that cannot be cashed out quickly. This means that once there is a large demand for Tether exchanges, Tether may face payment difficulties, leading to a price drop or even a collapse. This is the second risk of Tether.

Risk 3. Legal and regulatory issues

Unlike other financial institutions, Tether's custodian bank Deltec does not purchase insurance specifically designed to protect investors, such as the FDIC or the Central Deposit Insurance Corporation. In other words, if Tether is subject to large-scale theft or loss, it will be difficult for investors to receive compensation.

Although Tether claims to have registered an MSB license, it has not actually obtained strict financial supervision, which may mean that there are risks in business operations and investors cannot fully rely on the information currently provided. This is the third risk of Tether.

Although Tether has an important position in the crypto market, the risks and opacity behind it are still areas that investors need to pay special attention to. The above three potential risks should be carefully considered before using Tether.

What does USDT mean_Factors affecting Tether market confidence_Tether price fluctuations

Is Tether (USDT) worth investing in?

Despite all the controversies Tether has experienced, its current position in the cryptocurrency market seems to remain solid. Many people believe that Tether is a safe and stable investment option, but is this true?

First of all, we cannot deny the huge influence of Tether. Since its launch, it has dominated the market and become the most popular stablecoin today. The daily transaction volume is "billions of dollars" and not even Bitcoin can match it. This widespread usage means that most people believe in its stability and will use it as a bridge for transactions.

However, the financial issues behind it cannot be ignored. Many critics point out that Tether's financial data is not transparent and are skeptical about its true reserve margin content. Although Tether claims to have sufficient reserves, the lack of public information makes it difficult to determine the authenticity.

But on the other hand, Tether’s popularity means it’s unlikely to disappear anytime soon. Many people choose to trust it, not only because it is convenient, but also because "everyone is using it." So despite the risks, many investors still think it's relatively safe to use funds as excess in the short term.

As for long-term investment, since the price fluctuations of USDT itself are very small, it may not be an option that can bring significant returns. If you are looking for high risk and high reward, other options in the cryptocurrency market, such as Bitcoin or Ethereum, will be more attractive.

In addition, although Tether itself is not a scam, it has indeed been exploited by many scammers. From fake exchanges, fraudulent APPs to various scams, criminals often use the name of Tether to commit fraud. Therefore, whether you choose to invest or not, you should remain vigilant, do not be easily tempted by good promises, and be sure to purchase from reliable sources.

How to make money by buying Tether (USDT)?

Many investors use Tether for arbitrage. So, how is arbitrage realized, and how to make money by buying?

Arbitrage is basically divided into "two major strategies": one is to use the "price difference" between multiple platforms, and the other is to obtain "time difference" income by holding for a long time.

First, multi-platform arbitrage requires investors to buy USDT at a low price on platform A and then sell it at a higher price on platform B. However, this strategy is relatively difficult in practice because investors need to have in-depth knowledge of multiple platforms and continuously pay attention to market price dynamics. Therefore, this strategy usually requires professional teamwork and is difficult for ordinary investors to operate.

As for the long-term holding strategy, its risks are closely related to market performance. Traditionally, when the price of Bitcoin falls, people may turn to buying Tether; and when the price of Bitcoin rises, investors may consider selling Tether. But as Tether continues to sell Tether coins, this arbitrage space is shrinking. In addition, in the financial services provided by some cryptocurrency exchanges (such as Binance), depositing Tether will earn annual interest of up to 10%. This is also a very good way to invest.

When it comes to how to buy Tether, investors can generally use "two channels": exchanges and over-the-counter transactions. Exchanges such as Binance, OKX, etc. provide direct purchase functions. OTC transactions include: B2C, C2C, and P2P methods.

What does “over-the-counter” cryptocurrency trading mean? Over-the-counter (OTC) transactions are transactions completed directly between buyers and sellers, bypassing traditional cryptocurrency exchanges. This method is mainly used to conduct a large number of buying and selling operations quickly and efficiently without causing excessive price fluctuations in the open market.

When we trade on a general cryptocurrency exchange, the buy and sell orders will be publicly displayed and will directly affect the market price. But in the case of large transactions, if a large amount of Bitcoin or Ethereum is suddenly sold, it may cause large price shocks in the market.

OTC transactions are designed to avoid this situation, allowing buyers and sellers to directly negotiate the price and conditions of the transaction and then complete the transaction safely and privately. This is especially useful for larger organizations! However, OTC trading also has its risks. Without centralized regulatory guarantees like exchanges, you will face a higher risk of fraud. Therefore, it is crucial to choose a reliable OTC trading partner and ensure the safety of the transaction!

Where to buy Tether (USDT)?

Tether is currently the most popular stablecoin on the market and is widely traded with cryptocurrencies.

The following are the channels through which USDT can be purchased:

Channel 1. Trading through cryptocurrency exchanges

Many major cryptocurrency exchanges support trading of Tether.

Here are some well-known exchanges: Binance, OKX, Huobi, etc.

Through these exchanges, Tether can be purchased using other cryptocurrencies (such as BTC or ETH) or traditional fiat currencies (such as USD, EUR, JPY, etc.).

Channel 2: Through over-the-counter transactions

This is a method of trading outside of public exchanges.

Many large exchanges offer over-the-counter trading services, making it possible to buy Tether in large quantities without having a big impact on the market price.

Channel 3. Through P2P transactions

Some platforms allow users to trade directly with each other without going through an intermediary or exchange at all.

This usually involves the seller sending Tether directly to the buyer's wallet, and the buyer paying the seller via traditional payment methods.

Channel 4. Through cash/local transactions

Although this method is less common, in some areas, people will meet at a certain place and exchange cash for Tether.

Special note: before purchasing Tether, please be sure to confirm whether the channel you are using is reliable and safe. Also, please make sure your Tether is stored in a secure wallet and properly backs up your keys to prevent loss.

Tether (USDT) purchase tutorial

There are many crypto exchanges that support USDT. Next, I will take Binance, the largest exchange in China, as an example to introduce the registration and purchase methods in detail.

Android mobile APP download

Android phone users can directly use the browser to open the APP download address: https://static.jbzj.com/qkl/ba/baxz.html

Apple mobile APP download

Apple mobile phone users can check the tutorial below to register an overseas Apple ID, and then go to the Appstore to search for binance and download it.

Step 1: Create an Apple ID for Taiwan, China

Due to country restrictions on Apple mobile phones, we need to register an apple ID in Taiwan, China, before we can download the Binance software. Apple IDs in the United States and Hong Kong no longer work. Apple IDs in the US can only download the emasculated version of Binance. In Hong Kong, due to regulatory reasons, the apps of these exchanges may also be required to be removed from the Appstore. So our best option is to register an Apple ID in Taiwan, China.

1. Enter the official Apple account website through a browser search, find the small downward arrow in the upper right corner of the page, and click "Create your Apple ID".

Tether price fluctuations_What does USDT mean_Factors affecting Tether market confidence

2. Fill in our [last name and first name]. Here we change the country or region from [Mainland China] to [Taiwan], and here we can make up any date of birth. The email address must be one that has not registered an Apple ID. Whether you have a domestic Apple ID or a foreign Apple ID, you must have never registered one.

3. Set up our Apple ID password again. At least 8 characters, including uppercase, lowercase and numbers.

4. Enter our mobile phone number. Because it requires verification, we need to receive text messages and voice calls, so we can just fill in whatever phone number we have.

5. Enter the verification code and click [Continue].

6. At this time, we will receive a verification code in our mailbox. We check it in the mailbox, enter the verification code, and click [Next].

7. Enter the mobile phone verification code again, and then click [Next].

8. Now comes a very important step. After we log in to our Apple ID, first click the downward arrow next to log out and find "Personal Information".

9. Find and click [Country or Region], and then click "Change Country or Region".

10. For the next country and region, we still choose Taiwan, China. We must select "None" for payment method and do not add any payment method. Next is the billing address and shipping address. Here we need to use the Taiwan address generator. Let’s not close this page yet, let’s open a new page first.

3. Then he will give us a 16-digit secret key and a QR code. You can copy this secret key or save the QR code, then open Binance Google Authenticator and use the 16-digit key you just copied. Add new authenticator.

4. We copy this 16-digit key, and then open our Google Authenticator. Everyone downloads this Google Authenticator. Be careful not to download the wrong Google Authenticator. Then click the + sign in the lower right corner and enter the setup key.

5. We can fill in the account here casually, and then paste in the secret key we just copied. Click [Add], and now our Google Authenticator verification code has been generated. It's the six digits below. These six digits are our Google verification code. Copy this Google verification code.

6. Return to Binance, click [Next], paste the Google verification code we copied, and click [Submit]. Now our Binance Authenticator APP has been bound.

After the authentication is completed and the security settings are completed, we can buy coins on Binance.

5. Buy USDT, sell USDT

Buy USDT:

1. Click [Add Funds] on the Binance homepage and select [C2C Transaction].

What does USDT mean_Factors affecting Tether market confidence_Tether price fluctuations

2. For novice users, it will ask us "Have you ever used C2C transactions?", I will skip the novice guidance and select I have experience.

3. After entering, you can see that there are express zones, self-selected zones, strict zones and bulk zones.

4. As the name suggests, the quick area is more convenient and fast. We directly enter the amount of RMB we want to buy, and then we can buy the corresponding amount of USDT. It calculates for me here that I can buy about 140.44 U for 1,000 yuan.

Factors affecting Tether market confidence_Tether price fluctuations_What does USDT mean

5. The "self-selected area" is a little more complicated, but the self-selected area, the strict area and the bulk area are relatively similar. The difference is that the large area is specifically designed for large-amount transactions, and its limits are generally relatively high.

Factors affecting Tether market confidence_What does USDT mean_Tether price fluctuations

6. The "strict area" is equivalent to the selling area of ​​the self-selected area. The strict area only has the function of selling, which means that it is specifically designed for withdrawals. We can see that it has written a 100% compensation for us here. Because the merchants in Yan District are all Aegis merchants, they have deposited a large amount of deposits on the platform. If something goes wrong during our transactions with them, this will cause our funds to be frozen, our accounts to be blocked, etc. It will compensate us 100%, so when we withdraw money, it is safest to use this strict area.

Factors affecting Tether market confidence_What does USDT mean_Tether price fluctuations

7. When depositing money, we can directly use the buying function in this self-selected area, and then screen some more reliable merchants by ourselves. How to filter? First, we can filter the amount we want to buy, for example, I want to buy 1,000 RMB USDT, and then filter our payment method, for example, I want to pay using WeChat, click [Confirm].

What does USDT mean_Factors affecting Tether market confidence_Tether price fluctuations

8. We check this Aegis, so that we have a relatively high safety factor.

What does USDT mean_Factors affecting Tether market confidence_Tether price fluctuations

9. Let’s directly look at the following merchants that meet our conditions. The higher the order volume and order rate, the better. Then we click on his homepage to check when he became a merchant. We can see that this merchant's account has been created for more than 1,200 days, and the first transaction is relatively long ago. We need to look for merchants that have been registered for a long time, at least for more than half a year. Because the longer his account survives, it proves that his assets are safer, and he has done so many transactions without any problems. After confirming the transaction with him, we click [Buy] here.

10. After entering the amount we want to purchase, it calculates for us that we can receive 137.55 U, and then click [Place Order].

Factors affecting Tether market confidence_Tether price fluctuations_What does USDT mean

11. At this time, our order is generated, and the merchant's name, WeChat account, and payment QR code will be displayed to us. At this time, we need to leave the platform and add his friends in WeChat, or use the scan function to transfer money to him. After the transfer is completed, remember to take a screenshot to keep the voucher, then return to the platform and click [Upload Payment Proof].

12. Upload the screenshot we just took here, and then click [I have completed the payment, notify the seller]. In this way, after the seller receives the money, he will release the coins to us. In this way we have completed a deposit process.

13. However, I would like to remind everyone that you must not make any remarks during the transfer process. You must also use your Binance real-name name, WeChat account or Alipay account under your name to transfer money to others. These are the basic requirements for some transactions. Of course, if there are any problems during the payment process, you can also click [Chat] to communicate with the merchant.

14. After buying USDT, we go to [Assets] in the lower right corner and we can see that he has many accounts here.

Tether (USDT) Review

Most people think USDT is usable, but they still need to be aware of the risks.

Dcard netizens’ opinions PTT netizens’ opinions on Tether (USDT) News Compilation

In recent years, Tether has been closely watched by investors, researchers and the media due to the controversy and turmoil behind it.

Here is a summary of these important news:

Sorting out 1. Issues of financial auditing and real reserves

Tether promises to conduct regular audits to ensure that every USDT is backed by one dollar. However, the accounting firm Friedman LLP, which was originally scheduled to perform the audit, chose to discontinue cooperation in 2018 because the financial information provided by Tether was too simple.

Later, although Tether obtained a report from Freeh Sporkin & Sullivan indicating that it had sufficient bank deposit support, detailed financial data has not been made public. In fact, in 2019, Tether even admitted that only 75% of its reserves were backed by U.S. dollars.

Summary 2. Charges from the New York Prosecutor’s Office

The New York Prosecutor's Office revealed that Tether had no real U.S. dollar reserves for a certain period of time.

In addition, in April 2019, the prosecutor's office accused Tether of using its own reserves to fill an $850 million funding gap of its parent company.

By 2021, the two parties reached a settlement, and Tether agreed to pay a fine of US$85 million, but did not formally admit its fault.

Arrangement 3. Concerns about market manipulation

At the end of 2017, the activities related to Tether and Bitcoin prices attracted attention.

The U.S. Commodity Futures Trading Commission issued subpoenas to Tether and Bitfinex, suspecting that Tether may be manipulating the price of Bitcoin by issuing Tether coins. Research from the University of Texas also found that there is a correlation between the additional issuance of Tether and the rise in Bitcoin prices, raising concerns that Tether may be manipulating the market.

What does USDT mean_Factors affecting Tether market confidence_Tether price fluctuations

Sort out 4. Recent price fluctuations

Tether has recently seen a massive sell-off on several trading platforms, pushing the price slightly below $1.

The chief technology officer of Tether hinted on social media that competitors (such as Binance) may be involved in this fluctuation. At the same time, some analysts also pointed out that Binance may be planning a market attack on Tether, trying to improve the status of its own stable currency through various means.

Tether (USDT) FAQ Question 1. The stable currency UST has plummeted. Is USDT still safe?

The stablecoin TerraUSD (UST) decoupled from the US dollar and its price plummeted, which in turn had a huge impact on the entire cryptocurrency market. This incident has attracted the attention of many investors, and many people have wondered: Is it possible that USDT will follow the same path?

First, we must understand the classification of stablecoins. Stablecoins are divided into three categories: legal currency stablecoins, cryptocurrency stablecoins, and algorithmic stablecoins.

Use a table to let you clearly understand the differences between the three!

Features Fiat Stablecoin Cryptocurrency Support Stablecoin Algorithm Stablecoin

describe

Directly linked to fiat currency, each issued stablecoin is backed by equivalent fiat currency or fiat currency equivalents

Backed by other cryptocurrencies as collateral, the value depends on the collateral cryptocurrency

It does not rely on any actual asset support and uses algorithms and smart contracts to regulate supply to maintain price stability.

Linked assets

Fiat currency (USD, Euro, etc.)

Other cryptocurrencies (Bitcoin,

Ethereum, etc.)

No real asset support

advantage

The price is stable and easy to understand and accept

Decentralization, reducing reliance on traditional financial systems

Fully decentralized and highly flexible

shortcoming

Centralized management is required and there are regulatory and audit risks

High price volatility and may require over-collateralization to maintain value stability

Extremely dependent on algorithm efficiency, facing complexity and predictability issues

Among them, USDT is a "fiat currency stable currency", which means that each USDT is linked to 1 US dollar. Cash reserves are maintained by TEDA Limited in Hong Kong. However, in 2021, the company inadvertently revealed that its physical cash reserves accounted for only 2.94% of total assets. Other major assets include: commercial paper, trust deposits, guaranteed loans and corporate bonds.

In contrast, UST is an "algorithmic stablecoin" whose price is entirely determined by the decentralized algorithm on the Terra protocol, without any form of physical reserves behind it. Stability depends on another token, LUNA, which is a dual-token model. When the price of UST fluctuates, this algorithm will stabilize the price of UST by adjusting the supply and demand of LUNA coins.

But it is this stabilization mechanism that only relies on algorithms that makes UST susceptible to market changes. When the value of UST continues to decline, in order to maintain stability, the price of LUNA begins to fall, and a large number of new LUNA are created, hoping to maintain the value of UST in this way. As a result, the issuance of LUNA coins increased an astonishing 328 times in a short period of time, eventually causing the values ​​of both UST and LUNA to plummet and completely lose their stability.

Although USDT and UST are both stablecoins, their operation methods and the mechanisms behind them are very different. Therefore, the collapse of UST does not directly mean that USDT will have the same risk, but investors still need to remain vigilant about the reserve assets behind it.

Question 2: How to convert USDT into RMB?

The process of converting Tether to RMB includes the following 6 steps:

Special tip: do a small test before trading and withdrawing money to make sure everything works smoothly. In addition, try to choose an exchange with a good reputation and reputation to reduce unnecessary risks.

Introduction To Stablecoins, What Is The Largest Stablecoin USDT, And What Is The Market Structure?

It has been more than ten years since the birth of stablecoins, but it was not until recently that Circle, one of its major issuers, was listed on the New York Stock Exchange and its stock price soared eightfold in more than ten days, attracting widespread attention from investors. This article aims to introduce investors to the “magic” capabilities of stablecoins.

What is a stablecoin?

Simply put, a stablecoin is a cryptocurrency and a private currency whose currency value is linked to a stable asset such as a certain legal currency (such as the U.S. dollar), and has the characteristics of stable currency value. As of June 2025, the global stablecoin market value is approximately US$250 billion, and there are more than 200 stablecoins on the market, and this number continues to grow.

USDT (Tether) is currently the largest stablecoin, with a market value of more than 150 billion US dollars, occupying approximately 60% to 62% of the market share. USDT has been issued since 2014 and is pegged to the US dollar at a ratio of 1:1. It can be circulated on multiple mainstream blockchains such as Ethereum, Solana and Tron.

USDC (USD currency) is the second-largest stablecoin in terms of market value. Its market value will reach approximately US$61.5 billion to US$61.7 billion in 2025, with a market share of nearly 23% to 25%. USDC is issued by Circle, which is known for its compliance and transparency and is favored by institutional investors. The United States has the largest number of stablecoin projects, including USDC, USDP, TUSD, etc., and its regulatory system is relatively complete.

At present, the market has formed an "oligopoly" structure dominated by USDT and USDC, which together account for more than 85% of the stablecoin market. Most mainstream stablecoins are issued using a legal currency reserve model, and their reserve assets are mostly cash, U.S. Treasury bonds and short-term reverse repurchase agreements to support currency value stability.

In terms of international regulation and innovation, the U.S. Congress is accelerating legislation and promoting a series of legal processes that are beneficial to the crypto-asset industry, paving the way for the integration of digital assets and traditional finance. Hong Kong, China, has also passed the Stablecoin Bill to establish a robust and comprehensive regulatory framework and encourage institutional innovation through the "Stablecoin Sandbox" model. The European Union is formulating regulations to regulate crypto asset markets such as MiCA, and puts forward higher compliance requirements for stablecoins.

New tools for high returns on capital

Compared with other investment tools, stablecoin investment has the following significant advantages:

First, liquidity advantage. Coinbase Wallet users can obtain an annualized rate of return of approximately 4.7% by holding USDC, and the funds remain highly liquid and can be accessed at any time. This is more flexible than traditional time deposits or bond investments and meets investors' needs for financial freedom.

Second, income stability. The current pledge yield range of USDC on different platforms is 1.16%~10.88%, which is much higher than the low interest rate of traditional bank deposits, bringing investors a more attractive income option.

Third, technological convenience. Relying on blockchain technology, stablecoin investment realizes 24/7 transactions, global transfers and automated income distribution. Taking Coinbase Wallet as an example, USDC income is automatically paid through the Base Layer 2 network every month without a lock-up period. It supports multiple blockchain networks such as Base, Ethereum and Polygon, which greatly facilitates user operations.

Other platforms such as Binance offer annualized returns of up to 10.88% and adopt a flexible staking mechanism. Some decentralized financial platforms (DeFi) such as Trader Joe's specific USDC liquidity pool yields even as high as 211.52%, but high returns are often accompanied by higher risks, and investors need to weigh them carefully.

According to the above framework, the author compiled the following table to help investors fully understand the different profit opportunities and potential risks of stablecoins in the DeFi ecosystem.

The invisibility cloak that moves assets anonymously

Stablecoins enable rapid on-chain transfer of funds around the world, often within minutes, making traditional cross-border fund tracking increasingly difficult. This characteristic of stablecoins makes them widely used to bypass global financial restrictions, including tax evasion, underground gambling, fraud, and other illegal activities.

The latest data shows that stablecoins have become the preferred tool for circumventing traditional financial supervision and money laundering in cryptocurrency activities. In 2024, stablecoins will account for 63% of all cryptocurrency money laundering activities, and have replaced Bitcoin as the main tool for anonymous asset transfers. This is mainly due to the stable currency value and wide acceptance, making it an ideal means to transfer and hide illegal funds.

The biggest challenge in implementing financial regulation of stablecoins is tracking the ownership of funds and their movement. The core feature of blockchain is "pseudonymity" rather than complete anonymity. This means that although the transaction data is open and transparent, the address on the chain is not directly related to the user’s real identity, making it difficult to track the source and flow of funds. Especially against the background that criminals are constantly developing new money laundering techniques, which further increases the difficulty of identification.

For example: Cross-chain bridges: are increasingly used to transfer funds between different blockchains to obfuscate payment paths; privacy coins, such as Monero (XMR), provide stronger anonymity and are preferred by some users; “Peel chains”, which split large amounts of funds into a series of small, difficult-to-trace transactions; virtual currency mixers (Mixers): a common tool for hiding the source and destination of transactions.

Many decentralized finance protocols make heavy use of stablecoins. The lack of a centralized regulator provides additional opportunities for bad actors to use these platforms to launder money. Although various countries and industry organizations have been actively promoting "know your customer" and "anti-money laundering" regulations, requiring stablecoin issuers and exchanges to strengthen identity verification and transaction monitoring, due to their cross-border nature, fast transaction speed, and deep integration with DeFi, the implementation of these regulatory measures still faces many challenges.

To sum up, although regulatory agencies and blockchain analysis companies are continuously strengthening their ability to combat illegal financial activities, the rapid, global and pseudonymous characteristics of cryptocurrency, coupled with the evolving means of money laundering, have indeed made this field a "financial regulatory gray area" that requires continued strengthening of regulatory governance.

Efficient chain with low transaction costs

Stablecoins play a unique role in the cryptocurrency world due to the fact that their prices are pegged to a specific stable asset, such as the U.S. dollar. Not only do they provide the convenience of digital assets, they also circumvent the shortcomings of violent fluctuations in traditional cryptocurrencies (such as Bitcoin, Ethereum). Therefore, stablecoins can be regarded as “efficient chains with low transaction costs” in many aspects, especially in the following aspects.

First, the transaction speed is fast and uninterrupted 24/7.

Traditional bank transfers, especially international remittances, often take hours or even days to clear and are subject to bank working hours, holidays, etc. Stablecoin transactions are built on blockchain technology. As long as the network is not congested, transactions can be completed almost instantly no matter when and where. For example, a foreign trade company located in China needs to pay a payment to a US supplier. If it is transferred through a traditional bank wire, it may take 2 to 5 working days, and may be delayed due to time differences and bank processing time. But if both parties accept payment in stablecoins such as USDT or USDC, the payment can be sent from the digital wallet in China to the digital wallet of the US provider within minutes, with no time limit. In addition, suppose a multinational enterprise needs to allocate funds urgently at night or on weekends to deal with emergencies. The traditional banking system cannot meet the immediate demand, but the use of stable coins can transfer funds anytime and anywhere.

Second, transaction fees are low, especially compared to international remittances.

Although the blockchain transaction itself will generate "Gas fees" (network fees), this fee is usually much lower than the SWIFT fees of traditional bank international remittances, intermediary bank fees or third-party payment platform fees. For large transactions, the relative cost advantage of stablecoins is particularly obvious. For example, if a freelancer in Hong Kong provides services to customers in the United States, if the customer pays through PayPal or traditional bank transfer, he may be charged a handling fee of 3% to 5% or even higher, and there will also be a large exchange rate conversion loss. If payment is made through USDT, the gas fee for a single transaction may be only a few to more than ten dollars when the Ethereum network is not severely congested. On more efficient blockchains such as Tron or Solana, the fee may be as low as a few cents. For a payment of hundreds or thousands of dollars, the transaction cost is extremely low. Although stablecoin payments are not yet popular at the retail level, in some cryptocurrency-native communities or specific scenarios, the fees for using stablecoins for small payments are lower than some credit card fees.

Third, it is censorship-resistant and permissionless.

Stablecoin transactions are conducted on a permissionless public blockchain, meaning anyone can send and receive stablecoins without approval from a bank or financial institution. This provides an important alternative for some users in areas subject to strict capital controls or inadequate financial infrastructure. For example, in some countries, individuals or companies are subject to strict restrictions on transferring funds abroad. Through stablecoins, it is theoretically possible to bypass these restrictions and conduct international capital flows under the premise of compliance.

Fourth, stability and predictability.

Compared with more volatile cryptocurrencies such as Bitcoin, stablecoins have extremely small price fluctuations, making them a more reliable unit of account and value storage, significantly reducing the risks of currency price fluctuations for both parties to the transaction. If a business accepts Bitcoin as a means of payment, significant fluctuations in the price of Bitcoin between the time it is received and the time it is converted into fiat currency could cause the business to incur losses. If you use stable currencies such as USDT or USDC, after the company receives the payment, its value is almost the same as the US dollar, thus effectively avoiding exchange rate risks.

Fifth, new financial instruments to serve high-value, long-term industrial projects.

Stablecoins provide a new financial tool for high-value, long-term industrial projects, and are particularly suitable for project management involving many participants and complex capital chains. Based on the programmable payment and smart contract technology of stablecoins, fund allocation at each stage of the project can be automatically linked to the contract agreement, and payments are automatically made according to progress nodes, thereby effectively reducing trust costs and default risks. Multinational participants can realize the free flow of global funds through stablecoins, avoid the high costs and delays of traditional cross-border settlements, and improve financial security and compliance with on-chain transparent supervision. This brings a more efficient and controllable funding operation model to long-term projects.

Although stablecoins also face regulatory challenges, some centralization risks, and on-chain network congestion leading to rising handling fees, their fast, low-cost, and permissionless characteristics of global transactions make them an efficient tool that cannot be ignored in the current financial field. Especially in scenarios such as cross-border payments, international settlements, and circumvention of traditional financial barriers, the advantages of stablecoins have become increasingly apparent.

Introduction To Mainstream Currencies In The Currency Circle: What Are Bitcoin And Ethereum, And What Are Their Characteristics?

Today I will mainly take you to understand some of the mainstream currencies in the currency circle~

1. Bitcoin

Bitcoin is the world's first decentralized digital currency, born when Satoshi Nakamoto published his white paper in 2008. The biggest features of Bitcoin are decentralization and blockchain technology. The total amount of Bitcoin is limited, only 21 million, so it is also called "digital gold".

Currently the most widely used digital currency, it was born on January 3, 2009. It is a peer-to-peer (P2P) digital cryptocurrency with a total of 21 million coins. The Bitcoin network releases a certain number of coins every 10 minutes and is expected to reach its limit in 2140.

Bitcoin’s transaction speed is fast, fees are low, and it has high anonymity and security.

Ethereum is an open source blockchain platform designed to enable the development and deployment of smart contracts and decentralized applications. It features the use of a digital currency called Ether and can also execute smart contract code. Born in 2015, it was created by young programmer Vitalik Buterin. He gained some attention in the Bitcoin community, but felt that Bitcoin's capabilities were limited and began working on a new blockchain platform. As a development result of Buterin, Ethereum has received widespread attention and recognition in the field of cryptocurrency and blockchain.

Ethereum allows developers to write and deploy smart contracts to automate transactions and contract execution. It also provides a platform that allows developers to build decentralized applications that do not rely on centralized servers or service providers.

The advantages of Ethereum are fast transaction speed, low fees, programmability and flexibility, so it is widely used in blockchain games, finance, supply chain and other fields.

3. USDT (Tether)

USDT is an encrypted stable currency based on blockchain technology. The token name is "USD Tether" and is pegged to the US dollar. 1 USDT = 1 US dollar. The biggest feature of USDT is its stable value, which can be used for transactions in the currency circle and can also be exchanged between digital currency and legal currency.

USDT was originally launched in 2014 by a company called Realcoin, which later changed its name to Tether. Tether launched USDT based on the Bitcoin blockchain in 2015, and has since launched USDT on other chains such as Ethereum and TRON.

The main role of USDT is to provide a stable digital currency whose value is always anchored to the US dollar. This allows users to trade in USD values ​​in the cryptocurrency market without having to worry about cryptocurrency price fluctuations. USDT is also commonly used for transfers and transactions on cryptocurrency trading platforms, as well as for hedging, lending and other financial operations. In some cases, USDT can also be used as a replacement for traditional bank accounts, as it can act as a kind of digital dollar. However, it should be noted that USDT is not risk-free, and its value and market operation are also highly controversial. Investors need to be cautious when using it.

4. Litecoin

Litecoin is also a cryptocurrency based on decentralized blockchain technology. It is similar to Bitcoin and was created in 2011 by a former Google engineer Charlie Lee. Litecoin began as a fork of Bitcoin with the purpose of providing a faster and cheaper transaction solution.

Litecoin functions similarly to other cryptocurrencies. It can be used as a decentralized digital currency for transactions, payments, and store of value, as well as for investing and trading. Unlike Bitcoin, Litecoin has shorter transaction confirmation times, faster block generation, and lower handling fees, so it may be more suitable as a payment instrument in some cases. Additionally, Litecoin can also be used for fast, low-cost cross-border transfers due to its short network confirmation times and low fees.

It should be noted that the cryptocurrency market is highly volatile and everyone should invest with caution.

5. Grapefruit Coin EOS

EOS is an independent blockchain platform developed by Block.One and officially launched in 2018. It aims to provide a platform for decentralized application development and deployment, featuring high performance, flexibility and ease of use. One of the design goals of EOS is to solve the scalability, user-friendliness and security issues in actual blockchain systems.

The main features and functions of EOS include:

1. Decentralized Applications (DApps): EOS provides high-performance blockchain infrastructure, encouraging and supporting developers to build various decentralized applications, including games, financial services, social media, etc.

2. Democratic governance: EOS adopts the DPoS (Delegated Proof of Stake) consensus mechanism and provides a democratic governance system that allows voters holding tokens to jointly participate in the management and decision-making of the network. DPOS is similar to the U.S. parliamentary system. Each super node is similar to a member of the parliament. There are 21 super nodes in total, and they are jointly voted by all EOS holders. This "parliament" has great decision-making power over the entire EOS ecosystem. If a certain plan is to be implemented, 15 votes from the super nodes are required before it can be implemented.

3. Platform scalability: EOS aims to provide users with high-performance, high-throughput, low-latency blockchain infrastructure to support large-scale applications and users.

Overall, EOS is an open blockchain platform designed to support high-performance decentralized application development and attract developers and users by providing democratic governance and scalability solutions.
