USDT vs USDC: Stablecoin Showdown at Online Casinos

When it comes to online casinos, two stablecoins stand out: USDT and USDC. Both are asset-backed coins that mirror the value of the U.S. dollar, making them a safe choice for those who want to avoid cryptocurrency volatility.

USDT, launched in 2014, is the largest U.S.-based stablecoin with approximately $191 billion in value as of 2026 and $141 billion held in U.S. Treasuries. It's widely accepted at crypto casinos worldwide. In contrast, USDC, introduced by Circle in 2018, has a smaller market capitalization but also maintains a one-to-one value with the dollar.

The main difference between these two stablecoins lies in their reserve transparency. USDT publishes quarterly attestations, while USDC provides more frequent updates through monthly attestations from Deloitte and audited financials with the SEC. This disparity affects users' confidence in each coin's underlying value.
