Having done some amount of business in Ukraine, I can attest to how hard it is to move money into that country. Crypto really solves that use case, provided that there's some trading inside the country as well as flowing in.
There was some other thing with using US based debit cards over there, apparently it was an easier flow to fill up the US accounts and have them use it over there than to do a bank to bank transfer.
What about the crypto side of it?
