I have been using Yobit since 2017, and it is the 1st real exchange that I use because I am in Russia. The transaction cost there is not very high, 0.2%, however here there are a lot of tokens with tickers that confuse traders. For example on Binance has COMP = $430.48 (Compound), but on Yobit there is 1 other token: 1 COMP = $ 0.00006703 (Compound Coin), I absolutely cannot distinguish them. It is interesting!
Currently my account on Yobit is working properly, I like their InvestBox, with profit of about 1% per day. I'm not sure about its reliability, but it's pretty fun.
