Under sanctions, it is already very difficult to conduct cryptocurrency transactions with foreign companies. The state does not want money to leave the country and enter citizens' accounts from unknown sources. So far, all these restrictions have been successfully circumvented.
I used to frequently use one Russian international money transfer service. Then that service came under sanctions, and it became impossible to receive transfers in the country where I usually collected them. So I stopped using it. About two years later, I got a marketing phone call from this service, during which they asked me, among other things, whether I would be interested in receiving transfers from Russia abroad in cryptocurrency.
