Are you kidding me ?
45 USD for Fee

thier support center is really shit
I will emigrate to binance or bittrex.

Wow is that real? 45 USDT withdrawal fee for USDT?
That is ridiculous. You should move all your crypto out to another exchange and withdraw FIAT from there. Never return to HitBTC again because of the over-inflated fees they want to charge you.
