I periodically buy bitcoins on Matbi, then transfer them to an exchange where there is no option to use fiat, and cash out. However, it's not always profitable, as sometimes there are exchanges with better rates. The fees here are quite high, so it's not worth buying or converting crypto in small amounts. It's much more advantageous to do it in larger batches (from 10,000 rubles). As for the transfer time, it varies: sometimes the money arrives in 40 minutes, and other times you have to wait up to 2 hours. However, this depends not on the exchange but on the network's performance, as everything happens automatically, and requests are processed immediately after they are created. I haven't encountered any reliability issues; all transactions went smoothly. If I were to evaluate it objectively, the exchange is generally good because: 1) automatic operation – the absence of operators eliminates manual checks and delays in processing requests; 2) many exchange directions. I mainly use bitcoins and Sber-online, but other Russian banks, e-wallets, and various tokens are also available; 3) low limits. You can buy crypto from 750 rubles, and withdraw from 600 rubles. But for transactions less than 10,000 rubles, fixed fees apply. Percentage fees depend on the transfer method and range from 0% (usually for purchases) to 4.5% for withdrawals.
