So they've started pulling this off now? I think this is probably the first time I'm getting to see an exchange threaten to pull things like this off but seriously it's alarming. To start with I've never been a fan of bitget and most CEX.
Anyways I thought the OP would be moving his usdt off the exchange but he wants BTC instead that's why I suggested a DEX so he can change directly to BTC from his USDT since moving across multiple wallets could bring some security threats.
