I do not know what you're talking about. I like the exchange HitBtc and I have never been problems with her. The only one thing I do not like it's the bigger commission
I could say the same thing. I've been working with this stock exchange.
I conducted research there, from 2017 to 2018 the number of stock exchanges according to the crypt increased.
This means only one thing - the reduction of commissions is not far off.
Of course, some of the new exchangers will soon burst and exit the game.
