The cryptocurrency market offers a wide array of stablecoins, but the most prominent by market capitalization are BUSD, USDT, USDC, and DAI. These digital assets have gained popularity due to their unique combination of cryptocurrency benefits—such as fast processing, enhanced privacy, and robust security—coupled with the price stability of traditional fiat currencies.
Understanding USD-Backed Stablecoins
Stablecoins pegged to the US dollar serve as a bridge between the volatile crypto market and the stability of traditional finance. They enable seamless trading, lending, and borrowing while minimizing exposure to price fluctuations.
Why Multiple Stablecoins Exist
Despite sharing a common peg to the US dollar, stablecoins like BUSD, USDT, USDC, and DAI operate on different blockchains and cater to diverse ecosystem needs. Each token maintains a 1:1 value with the USD but varies in liquidity, underlying technology, transparency, and governance models. This diversity allows users to access various decentralized applications and crypto assets across multiple platforms.
An Overview of USD Coin (USDC)
USD Coin (USDC) was launched in 2018 by the Centre Consortium, a joint venture between Circle Internet Financial and Coinbase. It is the exclusive stablecoin supported on the Coinbase exchange and is primarily built on the Ethereum blockchain as an ERC-20 token.
As of recent data, USDC has grown significantly, with a circulating supply exceeding $26 billion and capturing over 23% of the stablecoin market share. Its expansion continues as it gains adoption across multiple blockchain networks.
How USDC Functions
USDC operates on Ethereum and is also supported on other blockchains, including Solana, Algorand, Tron, and Stellar. It is an open-source project, ensuring verifiability and transparency. Regular audits are conducted to confirm that the circulating supply of USDC is fully backed by an equivalent amount of US dollars held in reserved bank accounts.
The issuance process involves users depositing USD, which triggers a smart contract to mint an equivalent amount of USDC. This mechanism ensures a 1:1 backing and maintains trust in the stablecoin’s value.

Understanding Tether (USDT)
Tether (USDT), initially known as MasterCoin, was conceptualized in 2012 and launched by Bitfinex in 2014. It is a fiat-collateralized stablecoin designed to maintain a 1:1 value with the US dollar.
With a circulating supply of over $54 billion, USDT dominates the stablecoin market, accounting for approximately 58% of the total supply. It ranks among the top cryptocurrencies by market capitalization and is widely used for trading and liquidity purposes.
How USDT Operates
USDT is managed by Tether Limited, making it a centralized stablecoin. While it has faced scrutiny regarding transparency and reserve backing, recent developments have aimed to address these concerns.
Following a legal settlement with the New York Attorney General in 2019, Tether began publishing attestation reports detailing the composition of its reserves. These reserves include commercial paper, fiduciary deposits, reverse repo notes, cash, and treasury bills. Tether asserts that USDT is fully backed and provides regular updates on its circulation via the Omni Layer protocol on the Bitcoin blockchain.
Comparing BUSD, USDT, and USDC
When choosing a stablecoin, factors such as transparency, liquidity, and trust play crucial roles. Below is a comparative analysis:
- Transparency: USDC and BUSD generally offer higher transparency through regular audits and public reports. USDT has improved its disclosure practices but historically faced more skepticism.
- Liquidity: USDT boasts the highest liquidity and trading volume, making it ideal for high-frequency traders and arbitrage opportunities.
- Trustworthiness: USDC and BUSD are often preferred by users prioritizing verified backing and regulatory compliance, while USDT remains popular due to its extensive market presence.
Which Stablecoin Should You Choose?
Your choice depends on your priorities:
- Opt for USDT if you value high liquidity and widespread acceptance across exchanges.
- Choose USDC or BUSD if you prefer greater transparency, regular audits, and regulatory clarity.
