In my personal ranking of currency converters, there aren't many participants, and FastChange holds one of the spots, although not the top one. This is because I don't use it very often. The commission isn't always lower than that of other services; sometimes it seems a bit high. Nevertheless, it offers all the directions I need. I regularly buy cryptocurrency for trading and storage, not limited to just BTC; I also prefer ETH, LTC, and more rare altcoins. On the FastChange site, I often exchange DASH and ZEC, and once I even exchanged USDT - Tether, which I hadn't encountered in online converters before. Users of the EXMO crypto exchange can exchange vouchers for three main currencies: rubles, dollars, and euros. I only withdrew them once when I decided to stop working with that exchange. The rate turned out to be excellent, almost at face value. There are no hidden pitfalls in the service. All rates and commissions are stated upfront, and before exchanging, you will need to enter a captcha several times and confirm your agreement to the transaction. You can't accidentally exchange something. If you made a mistake and didn't account for the commission, that's your responsibility. Everything is as transparent as possible; the main thing is to read carefully. The minimum and maximum exchange amounts are set specifically. There are no exact values for each payment system; it all depends on the direction. In some cases, this makes sense: when exchanging electronic money for cryptocurrency, the minimum amount is higher than when exchanging between electronic wallets. In other situations, the differences in minimums for Qiwi and Yandex can vary across all directions except for cryptocurrency exchanges.
