The functionality is really interesting, and the multifunctionality is even a bit concerning. I’ve already registered and tried the service. I deposited rubles and bought a bit of Bitcoin and Ethereum. Everything is stored in the wallet, sometimes it grows, sometimes it falls. I haven't made a withdrawal yet, but I plan to check how it works. If everything goes smoothly, I will invest a larger amount. I read news and forums — it seems that people are mostly satisfied, it doesn't look like a scam.
