The exchange has a specific working schedule and rates, not much more to say. It's not available for exchanges at night (although there's a chance someone might be online, I've seen it happen once), but overall the working hours are quite convenient. What annoys me the most is the need for verification. I use cryptocurrency precisely for its anonymity, and here they ask you to identify yourself in order to sell that crypto. And the most frustrating part is that there are many such exchanges, and completely anonymous ones offer inflated rates, which forces you to use services like this. The rates here are good since they are tied to the top ones on monitoring sites and are updated every minute. It's not profitable to exchange at market rates here. So far, I've only exchanged BTC for Qiwi on Bitbit. Overall, I have no complaints. During working hours, the exchange processes transactions within a few minutes. The money arrives in the wallet quickly and without extra fees.
