Hi. I'm going to open crypto exchange. Who knows about that: Are there any laws which is connected with crypto currency? What about taxes for this project? I am interested in such countries as Russia, England, USA. In which country are crypto exchange transactions legal?
As long as you plan to have AML and KYC compliant exchange you are safe.
But you should really ask for financial advice based both on your location and citizenship not only where you plan to run the exchange. Especially if you're from the US.
Anyhow stay away from Russia, not that the us and the uk are the best choices.
If you look at the eu go for Cyprus or Malta or Gibraltar.
