If there are any Ukraine member here i would like to recommend this Ukraine based Exchange to them. Kuna Exchange currently using  https://kuna.io for their services. It has a market cap of 300K, its not much? Well as a lone country serving Exchange it sure is a very good amount. They have about 33 pairs of crypto market and 8 of Fiat. BTC, ETH, XRP, NEM, EOS are supported and so is the like of BNB, Tether. I personally use this exchange, and it has a positive review all over the web
