This exchange service doesn't have anything outstanding regarding the price ratio – there are both better and worse options available. However, transactions here are always quick, and the transfer amount matches what was stated; I haven't noticed any tricks or attempts at deception on their part so far. It's also worth noting that transfers are available 24/7 without delays, even at night and on holidays (the transfer time does not exceed 20 minutes). As for payment systems, the most popular ones are represented here (I usually use Yandex Money, QIWI, and Payeer for transfers to Sberbank, and the fees are reasonable – when transferring directly from Yandex Money, I lose the same amount). I also keep an eye on the rates through an app on my smartphone (for Android) – it's convenient to track changes in real time. Overall, this is a standard exchange service that has earned my trust.
