We have answered to all the support tickets. Our ETH node issue is now resolved, and the transactions still pending will be processed as soon as possible. We apologize for any inconvenience caused.
I encountered some problems. Yesterday, I exchanged bitcoin for eth through exch and sent it to my own uniswapAPP wallet. Then I exchanged eth and sent it to my own bitget exchange. But my account was frozen today and I can’t withdraw USDT. What should I do?
exch has been identified as the cleaning party for the currency theft incident in February. The ETH you exchanged from here is naturally considered to be stolen funds, so your transfer to the exchange will naturally be frozen.

This is not correct.
Funds are not "naturally co sidereal stolen".
I have sent funds from eXch straight to binance without any problems just about 2 weeks ago.
Those are not necessary the same coins from bybit. EXch created new addresses, received and send coins, there is a lot of volume in eXch.
