TRC-20 is the people's USDT: TRON settlement in ~3 seconds with fees usually under a dollar, which is why it dominates real-world stablecoin transfers. For a dollar-stable bankroll with minimal friction it's our default recommendation at Duel — deposit from $5, play with zero volatility, cash out instantly. Just double-check you've selected the TRC-20 network on your exchange before sending.
