How do you ban this? It’s not part of swift or any us govt. backed global financial rails. If Iran(a sanctioned entity) supports this then this is more proof that the thing works.
China already bans crypto. If America and Europe followed suit, the market for crypto would quickly collapse
I’m not gonna comment on if it’s a good idea or not, but the US government could make it illegal for any financial institution that does business in America interacting with crypto.
They could also make it illegal for any US financial institution to do business with any financial institution that interacts with crypto.
They could probably also make it a crime to buy/sell crypto in America.
