Use cryptox.pl, no KYC, imediate withdrawals, best price, lowest fee.
I used the cryptox.pl exchange around 4 months ago when I could not verify my account on Bittrex.
After succesfully verified, I switched back to Bittrex till now.
My experience with Cryptox.pl was good, but the problem is daily volume on the one is too low.
It's hard to sell or buy coins at your expected price.
Volume raised since then, now it is about 20% total GBYTE volume.
coinlib shows fake volume for Bittrex and Upbit as both exchanges show the same volume as their.
