I don't see much of a need for USDT or any stable coin to be on centralized exchanges for much longer. Its useful as a place to park value on-chain via DEXs in between trades, kind of like Treasuries IRL. Even for Bitcoin its actually easier to trade WBTC on an EVM chain with stable coins. IMO It's silly to hold anything on a central exchange, they should go away for everything but fiat on/off ramps.
