Tether (USDT)

Tether (USDT) holds at $0.9995, losing a trivial 0.03% daily, underlining its role as the go-to haven as altcoins bleed. With a market cap of $142 billion, it is 30% larger than the runner-up stablecoin, USDC, which saw its market share slip to 18%. This stability outperforms #3 BNB's 2.9% daily drop, making Tether the top performer on this list by price resilience. Its 24-hour trading volume of $95 billion dwarfs Bitcoin's $28 billion, proving that traders flock to USDT during volatility, a pattern confirmed by a 14% volume spike in the last six hours alone.
