I recommend the Belarusian exchange Bynex. It offers over 250 currency pairs, including Bitcoin and new coins. The main feature is that direct payments from Russian and Belarusian bank cards are accepted. You can not only top up your ruble account from the card but also immediately purchase cryptocurrency. Verification is quick, taking a maximum of half an hour. The withdrawal fee is only 0.25%, which is one of the lowest rates in this field.
