Is it easy to withdraw money off this platform. Are any problems with it exist. I am interested first of all about how to withdraw NEO from Bittrex. Because these coins I have the most and operate them very often. Is it possible to convert NEO coins into dollars or euro or just withdraw coins on USB wallet.
