1) Personally, I really like the idea of a Cryptonator. Minimalistic design, nothing more, all completely in Russian and online. Access to a personal multi-currency account is carried out around the clock, from anywhere in the world where there is Internet, both from a computer and from a smartphone.
2) the Service allows you to replenish a multi-currency online account in rubles or dollars, after which the user can instantly exchange Fiat currencies (the service supports: dollar, Euro, ruble, hryvnia) for cryptocurrencies.
3) Separate positive moment — support Ripple.
4) the exchange Rate is more profitable than in popular exchangers.
5) the Service maintains high safety standards. Encrypted SSL connection via HTTPS Protocol, two-factor authentication, trusted IP addresses. After registration, you must configure the security to the maximum.
6) Some exchanges (for example, Binance) do not replenish the account with Fiat currencies. With the help of a Cryptonator, you can make rubles to a multi-currency account, exchange it for a cryptocurrency and send it to a stock account. Similarly, you can make a withdrawal in the opposite direction.
7) the Interface is so intuitive, simple and convenient that I do not see the point to describe the registration procedure and the main working functions.
8) Referral program. By registering at this link and making exchange transactions in the amount of $ 1000 You will receive $ 10.
