I don't mean to be rude or anything of course, but I am really curious to know... How can bitcoin be banned ? I mean, in general, let's say that you wanted to ban bitcoin, what would you need to do ?
Basically, you can't ban something that you cannot control. The government nor any private establishments don't have control over Bitcoin. That is what explains why some governments are so afraid and hate Bitcoin.
They can prohibit Bitcoin exchanges and local custodial wallets in an effort to prevent Bitcoin, but still people can transact online using the international platform and store Btc in their cold wallets.
