A little late to this one. Is it 100% sure/proven that Visa is going to play ball with these guys? I remember a few months ago Visa pulled support from some crypto cards (wavecrest). It doesn't seem like Visa wants to be used with anything crypto related.
Get your facts right. Visa suspended Wavecrest not because Visa doesn't want to have anything to do with crypto related but because Wavecrest violated Visa's policy. Visa has other approved card programmes that use fiat funds converted from cryptocurrency in a number of jurisdictions. You need to do more due diligence instead of just dishing it out there.
