Global Overview of the Cryptocurrency Exchange Market
The global cryptocurrency exchange market has shown strong growth momentum. According to market analysis, the market was valued at approximately $27 billion in 2024, and is forecast to reach $84.8 billion by 2034, with a compound annual growth rate (CAGR) of 12.6% projected for 2025-2034. This growth is mainly driven by rising crypto adoption, increasing demand for crypto derivatives and advanced trading tools, continued growth in the number of retail investors, and the gradual clarification of global regulatory policies.
Cryptocurrency exchanges are mainly divided into two categories:
- Centralized Exchanges (CEX): Operated by companies or institutions, responsible for user asset custody, account management, and compliance matters. Well-known CEXs include Binance, OKX, Coinbase, and others. Security is a key focus for CEXs, which typically employ technologies such as two-factor authentication (2FA) and cold wallet storage to protect user assets.
- Decentralized Exchanges (DEX): Run on blockchain smart contracts, allowing users to trade directly through their wallets, with assets held by the users themselves, eliminating the need to trust third parties.
Notably, Coinbase, an important player in the industry, became the first cryptocurrency exchange to go public in the United States via a direct listing in April 2021. By May 2025, it further became the first crypto-related stock to be added to the S&P 500 Index.
However, risks also exist in the market. For example, in September 2026, reports indicated that some platforms (such as FTR and the BOT public chain CA supercomputing protocol) were accused of being Ponzi schemes, with users encountering situations where they were unable to withdraw funds and were lured into making deposits to "unlock" their funds. Investors must remain vigilant and exercise careful due diligence when choosing exchange platforms.
USDT: The Cornerstone of Stablecoins and Its Challenges
USDT (Tether) is a stablecoin pegged 1:1 to the US dollar, first launched in 2014 (originally named Realcoin). Its core goal is to provide a crypto asset with stable pricing and low volatility, while retaining the advantages of fast, borderless cryptocurrency transactions.
USDT's Core Functions and Mechanisms
- Trading Quote Unit: USDT has become the universal quote unit in the cryptocurrency trading market, with most mainstream and non-mainstream cryptocurrencies using USDT as their pricing benchmark, such as BTC/USDT, ETH/USDT, and others.
- Store of Value and Hedging: During periods of severe volatility in the cryptocurrency market, many traders temporarily convert their assets into USDT to hedge risk, making it an important tool for storing value and hedging.
- Cross-Border Payments and DeFi: USDT plays a key role in cross-border payments and decentralized finance (DeFi), owing to its fast transfer speed and low cost.
USDT's stability is maintained by the following three pillars:
- 1:1 US Dollar Asset Reserves: Issuer Tether claims that every USDT it issues is backed by an equivalent amount of US dollar assets held in reserve, primarily consisting of US Treasury bills, along with some Bitcoin, gold, and other assets.
- Minting/Burning Mechanism: Tether adjusts the circulating supply of USDT by minting new tokens and burning old ones, in order to maintain its peg to the US dollar.
- Market Arbitrage Mechanism: Market participants engage in arbitrage, buying or selling when USDT's price deviates from $1, helping it return to its peg.
As of September 2026, the price of USDT has generally remained between $0.9997 and $1.00, with a market capitalization of approximately $186 billion, a circulating supply of roughly 186 billion tokens, and daily trading volume as high as approximately $128 billion, accounting for about 60% of the stablecoin market share. USDT is natively deployed on more than 10 mainstream blockchains and, through bridging technology, can be used across more than 80 networks.
Risks and Regulatory Challenges Facing USDT
Although USDT plays an important role in the crypto market, it also faces multiple risks:
- Credit Risk: The transparency of Tether's reserve assets has long been questioned. Critics argue that a large portion of its reserves are not held in cash, which could mean they cannot be fully honored in the event of mass redemptions, potentially causing it to lose its peg.
- Regulatory Risk: Global regulatory policies on cryptocurrencies and stablecoins are increasingly tightening. For instance, the EU's MiCA regulation will take effect in July 2025, and Tether may currently fail to meet the regulation's requirements, which could limit its use in the European market. The US is also considering legislation that would require stablecoins to be 100% backed by cash and short-term US Treasuries.
- Liquidity Risk: Under extreme market conditions, such as mass redemptions or market panic, USDT's liquidity may be insufficient; there have been instances of brief de-pegging to $0.95 (for example, during the 2023 Silicon Valley Bank crisis).
- Legal and Compliance Risk: Tether and its affiliated exchange Bitfinex have previously been accused of misappropriating funds. USDT has also been widely used for illicit fund transfers, such as money laundering. In order to comply with anti-money laundering (AML) regulations, the issuer has the authority to freeze USDT addresses involved in illegal activities.
- Platform and Operational Risk: Choosing an unsafe or non-compliant exchange platform may lead to loss of funds. Over-the-counter (OTC) trading carries extremely high risk due to the lack of regulation and third-party safeguards. In addition, on-chain operational risks such as phishing websites, fake apps, malicious contracts, and lost private keys also warrant caution.
Global Regulatory Developments and China's Policy
Regulators around the world are taking an increasingly cautious stance toward the cryptocurrency market. For example, Chinese regulators have explicitly stated that virtual currencies do not have a legal status equivalent to fiat currency, and that conducting virtual currency-related business activities within China constitutes illegal financial activity, which is strictly prohibited across the board. Overseas virtual currency exchanges providing services to residents within China via the internet are likewise considered illegal financial activity. China will continue to crack down on virtual currency "mining" activities and related illegal and criminal activities.
Internationally, institutions such as the US Securities and Exchange Commission (SEC), the EU's MiCA regulation, the Hong Kong SFC, and the Monetary Authority of Singapore (MAS) are all actively formulating and implementing cryptocurrency regulatory frameworks, aiming to strike a balance between protecting investors, preventing financial risks, and fostering innovation.
Given the complexity and high risk of the cryptocurrency market, investors must fully understand the associated risks and strictly comply with the laws and regulations of their jurisdiction before engaging in any trading activities.
