Lol. Hashrate will move, regardless. Their may be pain during transition but the net result will be even more decentralized mining as the non-“public” miners move to other locations/pools with better conditions. Either the economics of bitcoin work, or they don’t. They are based on allowing the free market to do its thing. I don’t believe this can be stopped. If authorites squash/capture one market, two free ones will pop up to replace it due to incentives alone. Nah, if there is any brains at all with the authorities, best to keep a quiet eye on it as-is less they force it adapt and decentralize even further. China made a big mistake. I suspect the IS may learn from that.
