Quite funny to read comments from people asking what use is crypto. Can tell they have probably never left West Virgina.
Don't think it would be that useful for Iran though as they are already RMB earners, and RMB financial markets are still a bit questionable (there is depth, I don't think anyone knows why this depth exists or what it is actually for, just state-linked banks moving paper between themselves furiously).
Not only that the Chinese Yuan is probably more interesting given they can buy more things with it from China things like consumer tech/products, chemicals and rare earths for weapon systems etc.
China has probably one on another blockchain but I am not sure how easy it is to exit their ecosystem or convert it to anything else...
