Comparing Tether to Other Major Stablecoins like USDC and DAI

Stablecoins have become an integral part of the cryptocurrency ecosystem in recent years. As their name suggests, stablecoins are designed to have a stable value and not be as volatile as other cryptocurrencies like Bitcoin and Ethereum. Tether (USDT) was one of the first stablecoins ever created and remains the most widely used. However, other stablecoins like USD Coin (USDC) and Dai have emerged as popular alternatives. This article will compare Tether to these other major stablecoins across several key factors.


Stablecoins attempt to tackle one of the main criticisms against cryptocurrencies - their extreme volatility. Cryptocurrencies like Bitcoin regularly see double digit percentage moves in a single day, making them difficult to use as a reliable store of value or medium of exchange. Stablecoins aim to solve this by pegging their value to an external asset like the US dollar. This allows them to maintain a steady value and achieve price stability. Tether has dominated the stablecoin market since its creation in 2014. However, rising concerns around transparency and centralized control have led to the growth of alternative decentralized options like USDC and Dai. This article will analyze how Tether stacks up against these stablecoins across criteria like market capitalization, backing reserves, decentralization, and adoption.

Market Capitalization and Trading Volume

Tether has a commanding lead in terms of market capitalization, which refers to the total value of coins in circulation. Tether's market cap stands at around $65 billion, dwarfing that of USDC at $43 billion and Dai at just over $6 billion (CoinMarketCap). Tether also leads decentralized stablecoins by a wide margin in 24-hour trading volume at $48 billion. However, USDC and Dai have been gaining ground steadily. USDC's trading volume is now over $3.5 billion compared to Dai's $285 million. Tether's first mover advantage has provided it unparalleled liquidity and network effects. But questions linger on whether alternative stablecoins can challenge its dominance in the coming years.

Backing Reserves and Stability Mechanisms

A key aspect of stablecoins is how they maintain a peg to the underlying asset, usually the US dollar. Tether controversially relied on a fractional reserve model for years where all coins were not backed 1:1 with dollars. It has now abandoned this approach and claims to be fully backed with cash and cash equivalents. USDC and Dai take a more conservative approach. USDC maintains a 1:1 reserve ratio with US dollar holdings and attestations validating this. Dai uses overcollateralization to maintain its peg whereby users deposit crypto assets valued higher than the Dai they generate. This model has allowed both USDC and Dai to better maintain stability around their $1 pegs compared to periods of deviation by Tether.

Decentralization and Transparency

Tether is operated by the private company Tether Limited. This centralized control has led to opacity in its operations and concerns around manipulation. USDC is also managed by a consortium of private entities in Centre but offers regular attestations on reserves. Meanwhile, Dai is considered the most decentralized stablecoin. It is issued by the MakerDAO protocol which uses smart contracts on Ethereum. Anyone can monitor Dai's monetary policy and collateral backing on chain. While Tether remains the dominant player, USDC and Dai offer greater decentralization and financial transparency for those who prioritize these factors.

Adoption and Use Cases

Being the first mover, Tether is accepted at virtually every major exchange and DeFi platform. It accounts for over 50% of Bitcoin trading volume due to its liquidity. USDC also has wide support across DeFi applications and exchanges, partly due to Coinbase's influence. Dai has an advantage on Ethereum-based protocols but lacks the network effects of Tether and USDC currently. In terms of remittances, Tether and USDC can move faster and cheaper compared to traditional finance. Dai's decentralized nature provides censorship resistance but makes it harder to integrate into existing fintech. Tether is also making a push into the payments space with a Tether-based USDT card. But high fees and limited merchant acceptance remains a roadblock for crypto-based payments currently.

"As the first major stablecoin, Tether will always hold an important place in crypto history. However, concerns around its reserves and centralization have opened the door for more transparent competitors like USDC and Dai to gain market share over time," says Michael Peterson, a long-time cryptocurrency analyst. "But Tether retains enormous liquidity advantages that will make it very difficult for another stablecoin to overtake it anytime soon."

Potential Risks and Challenges Facing Tether

Tether faces ongoing regulatory uncertainty and legal issues due to its leadership and past lack of transparency. Any disruption to its operation could have a severe impact on the broader crypto market given its importance. Tether also needs to manage its backing reserves carefully to maintain stability. A potential mass redemption event could put heavy strain on its available assets. These tail risks, although unlikely, do remain and make some wary of Tether's continued dominance.

Can a Stablecoin Truly Decouple from the Broader Crypto Market?

Stablecoins are closely tied to the crypto market outlook even though they aim for price stability. For example, periods of severe crypto downturns often lead to stablecoin weakness relative to the dollar. They are also tied into broader crypto adoption. As we've seen, stablecoins are heavily utilized in crypto trading and DeFi. As these use cases grow, stablecoin demand rises. But setbacks in the crypto industry can dampen stablecoin momentum. Truly standing alone from crypto market cycles may be difficult. For now, the success of leading stablecoins remains linked to that of the broader crypto and blockchain space.

Which Stablecoin Is Best for Payments and Remittances?

While Tether, USDC and Dai can all be used for payments, Tether and USDC may have some advantages currently. They have wider acceptance and integration with payments infrastructure. Their backing by large centralized entities provides greater connectivity with existing financial and fintech systems. This allows for faster on-ramps and off-ramps with traditional currencies necessary for payments. Dai has benefits like censorship resistance but needs better UX and real world integration before becoming viable for mainstream remittances and payments.


Tether remains the dominant stablecoin thanks to its first mover advantage and deep liquidity. However, stablecoins like USDC and Dai are rapidly gaining ground with their improved transparency and decentralized models. All three have roles to play in the growth of DeFi and the wider blockchain ecosystem. As regulations evolve, stablecoins may need to transition to being fully backed and licensed like USDC if they want to maintain regulatory compliance. But for now, Tether retains its leadership position and will likely continue as the most traded and used stablecoin asset. Yet its market share will gradually decline as alternatives like USDC and Dai address concerns around Tether's centralization and transparency.
