It has been 48 hours now my 2.10BTC is blocked. I am aware about recent problems with cashout and BTC but BINANCE did my cashout in 2 hours today. Does liqui put the minimum of fees in their withdrawals?
I have issued 3 tickets, no response yet.
I m loosing confidence in Liqui, the more hours i wait to receive my BTC, the more i think about not trading overthere anymore.
