The US and China regions control the vast majority of the hashrate.
Two observations:
1. Wtf is the rest of the world waiting on?
2. The American culture is one of individuality and the Chinese is collectivism. The battle over hashrate will be the first time in history such competition can take place overtly and digitally.
For the American model to continue it will require many individuals to agree to row in the same direction for a common cause. We have a common cause worth uniting for.
