Greetings
I am aware of a bank with a similar business structure as you suggested in your post, operating in Dominica with a company in St.Vincent and the grenadines. Internationaloff is correct about knowing your customer base.
I have exchanged my US dollars for Bitcoin and vice versa
2) wired the bitcoin to coinbase/ then from coinbase credited my bOa account, you could send from coin base to your leupay account
