USDT vs USDC: Which Stablecoin is Best for Investors? (2025)

USDT vs USDC comparison has always been on, and for understandable reasons.

Cryptocurrencies are often criticized for their volatility. 

Prices swing rapidly, and while that brings profit opportunities, it also introduces risk. Stablecoins solve this challenge by pegging their value to stable assets, mostly fiat currencies like the U.S. dollar.

In 2025, stablecoins are no longer just trading tools.

They power remittances, decentralized finance (DeFi) protocols, e-commerce payments, and cross-border settlements.

Out of all stablecoins in circulation, USD Coin (USDC) and TetherUSD (USDT)  dominate, controlling over 80% of the stablecoin market share.

This raises a crucial question of which stablecoin is better for crypto users in 2025 between USDT vs USDC.

USDT vs USDC: Background and Issuers

Launched in 2018 by Circle, in partnership with Coinbase under the Centre Consortium, USDC is a regulated stablecoin digital currency.

It was managed by the Centre Consortium until 2023, but is now primarily overseen by Circle.

Known for being fully backed by U.S. dollar reserves and U.S. Treasury bonds, USDC has built a strong reputation as a transparent and regulation-friendly stablecoin.

On the other hand, USDT was launched in 2014 by Tether Limited.

Standing as the oldest and largest stablecoin in terms of market cap, USDT is widely used for trading and payments.

However, its history is clouded with controversies around transparency and reserve audits.

Despite that, it still dominates crypto markets in terms of liquidity and daily trading volume.

USDT vs USDC: Key Differences; Transparency, Regulation, and Backing

Transparency

USDC

According to the company, all USDC tokens are backed by a US dollar or cash equivalent asset.

These assets are held by Circle in its publicly visible reserves, with assurances issued monthly by a Big Four accounting firm. Particularly, the issuing company, Circle, publishes monthly USDC reserve reports, making it easier for users to trust its 1:1 peg with the dollar. 

USDT

Likewise, all USDT tokens are pegged at 1-to-1 with a matching fiat currency and are backed 100% by Tether’s Reserves, according to Tether.

As part of Tether’s commitment to transparency, the company publishes Reserves reports quarterly  while information about USDT in circulation is typically published daily.

In addition, an independent third-party accounting firm BDO Italia executes Independent Auditors’ Reports on Tether’s Reserves reports quarterly. 

These reports aim to demonstrate that Tether’s Reserves are greater than the redemption value of USDT in circulation on the dates reported. However, while claiming to be fully backed, Tether has often been criticized for lack of consistent independent audits. 

Regulation

USDC is issued by Circle, a regulated financial service business that follows strict US laws and standards.

Accordingly, USDC aligns closely with U.S. regulators and financial standards, making it a regulatory-compliant stablecoin. 

USDT, on the other hand, operates with fewer regulatory ties, which makes it more accessible globally but raises trust concerns. 

Backing

USDC is fully backed by U.S. dollar–denominated assets of corresponding value, which are maintained as reserves for the benefit of its holders. Notably, cash reserves are deposited with regulated financial institutions.

Meanwhile, the Circle Reserve Fund, which may comprise short-dated U.S. Treasuries, overnight Treasury repurchase agreements, and cash, is held in custody by The Bank of New York Mellon and managed by BlackRock. 

On the other hand, USDT is primarily backed by U.S. Treasury Bills.

Data shows that Tether reached an all-time high of total exposure in U.S. Treasuries approaching $127 billion in Q2 2025.
