I have been trading on the stock exchange for more than a year, of the obvious problems I can mention the design of the site, or rather, its absolute inability to adapt to mobile devices.
In general, I have a very positive attitude to the exchange, because I use it as an exchanger for buying cryptocurrencies for rubles and transferring them to other exchanges (via litecoin).
The Yobit exchange is a very good choice as an exchanger, because 1) can be replenished in rubles 2) does not require KYC 3) 0% commission for replenishment 4) the rate for the top crypt may differ by 3-5% with the main exchanges.
Another drawback of the exchange is dead coins, there are a lot of them here. There are almost no transactions for such coins, and some of the coins have only empty glasses. More than 50% of such coins! But nevertheless, I am satisfied with the exchange and am ready to recommend it.
