This exchange turned out to be very understandable for me, and most importantly, it works without failures. Not so long ago I bought cryptocurrencies at my disposal there, and this is the case when even such incomprehensible matters worked quite smoothly and without failures. Most of the concerns were about the withdrawal of coins from the account, but hitbtc should be commended, as it went well with it. In addition to bitcoin, I also bought ZEC and LTC. Very commendable service.
I didn't find any significant shortcomings, since everything I did worked well. However I'll see how the exchange performs in the long run, but for now I am happy with that.
