I exchanged bitcoins for rubles at Sberbank through Payget. The payment went through quite quickly, in just 10 minutes, but of course, I was lucky since the network wasn't busy. No extra information is needed for the transaction; the process is similar to other exchangers: you enter the payment details, confirm, and receive the funds. Everything is done on the website, which immediately warns about the two confirmations in the Bitcoin network and shows the current exchange rate. The service takes a small percentage for the conversion, and at least in this direction, the fee is lower than many other exchangers.
