I am in the same shoes. The company formed my belize corp trying to sort out a bank account for 6 months and absolutely no luck. Polish, German banks would not touch crypto either.
I have no idea how big ICO firms doing it, but I would need an answer ASAP too.
Have you tried to form a new company in a better jurisdiction? Maybe the issue is Belize?
or have you tried to buy already established company with bank account? I know its around 10-15k, but already formed and apparently established.
I saw a website advertising such companies.
