Most banks except one or two (which not accept non-EU citizens) will reject and close your account when you will try to fund the account with money, which is connected with
crypto.
So you need crypto-friendly
EMI - Mistertango, Bilderlings, ePayments (all of them accept non-EU citizens and don't care about your place of residence, of course, if this is not North Korea).
You will fund these accounts by money revived from crypto-trading or something else. This EMIs provides possibility only SEPA transfers with your name in bank details (no SWIFT).
Also, personally I don't like to hold my funds at
EMI. I prefer banks. So you need to open a bank at SEPA (
Bulgaria and Romania are not so far from Serbia). When you will open accounts at these banks you will be able to fund then through your account at Mistertango via SEPA payments (this is very cheap) and the most important your money will be "clean" from crypto-relation.
I proposed Ameria for diversifying funds and they propose remote open of account. So why not? The best decision to take your money in two or three baskets.
