Does it have to do with server?
I know I might be answerings this question for myself, but it never hurts to ask.
1. Firstly, If they have a community like other exchanges like Binance, has other users reported
2. Secondly, have you written to their support and what was their reply?
3. Finally, dude...get your money out of that exchange after each day's trade. It only take some few dollars (less than $3) to send it over there again to trade so why go through this headache of having to think all day about the safety of your funds when you could have kept it safely on your wallet.
