CoinDesk reported that USDC accounted for about 70 percent of adjusted stablecoin transaction volume in the first half of 2026, while USDT held roughly 25 percent by that measure. The same report said adjusted stablecoin transaction volume reached a record 1.79 trillion dollars in June.
That does not mean every trader should treat one stablecoin as universally better. USDC and USDT solve overlapping but different workflow problems. A trader should compare where the coin has the deepest pairs, how redemptions work, whether the exchange charges different fees, and how the asset behaves during stress.
Regulation also matters. Stablecoins are moving closer to mainstream payment and market infrastructure, but legal frameworks differ across jurisdictions. The useful due-diligence question is not only whether a token is widely used, but whether the trader understands issuer risk, reserve transparency, freeze powers, depeg history and on-chain network risk.
For platform selection, stablecoin choice belongs in the same checklist as liquidity, withdrawal rails, proof of reserves and account security. The strongest setup is usually one that gives traders more than one settlement route before a market outage or redemption queue appears.
