Yes I have everything i get it submitted all documents. Anyway I don’t offer crypto. Just sell buy exchange other all payment method Skrill Neteller pm Payoneer etc. and sorry for that writing about crypto
I am not sure about the trading of skrill, neteller, perfect money and payoneer are legal in Bangladesh or not. But to get licence of trading I think you should have money exchange licence, which is not easy to get. That should be costly, anyway, best wish of your business.
