I use CEX.io for crypto-fiat gateway as they accept cards from Serbia an I never had a problem with making my money crypto-clean. I've withdrawn as much as 2000$ in one go and I didn't experience any problems ever, meanwhile, the transactions are instant. I never thought using SEPA banks would be important and I still don't. If I have a debit card associated with my banking account I can use that or a wire transfer, so I would just need a sound bank account for non EU/USD citizen, multicurrency or at least three major once: EUR, USD, and GBP with an ATM withdrawal method︀ with low fees. Do you think that Ameria bank could offer me this service, do︁ you have an account there?
