Every country are starting to ban. What if USA ban? how will it go?
The United States are very liberal so I doubt that will ever happen. It's the land of opportunities or so they say, so it would be very strange if they attempt to ban bitcoin. I think that their vision on crypto stayed a lot more clear after the SEC hearing, and things look good. Crypto will get regulated, and will probably find it's way as a payment system in the US, and the rest of the world, and I doubt it will ever get banned.
Bans are for countries like China, not the US. Talking about China and bans, I'm curious to see how their last attempt to shut own BTC access through exchanges to their citizens, by using their firewall will turn out. They will probably fail, and it will be even more clear that BTC can't be banned.
