And the 2400 US bitcoin nodes would go offline.
What would happen to price?
What would happen to hash power?
How long would it take to recover?
Let's speculate!
I am not sure what happened to the price because the bitcoin price does not just move because of one action. It will move from what traders demand and supply. I think that will happen too with the hash power, maybe it will reduce for a while, but that will not affect to the most hash power because we know that the mining process is not just come from the US. There are many other countries will still mining bitcoin, and if the US make bitcoin illegal, we don't have to worry about that. The recover will always happen, but we don't know how long it will recover, and bitcoin does not depend on one or two countries but it depends on how people use bitcoin itself.
