Please, no China conspiracy theories.  Everyone knows China is not a long term threat to Bitcoin due to commoditization of ASIC occurring.  Having lots of hash power in China right now is only a symptom of everything on earth being manufactured there - people using their slaves as global labor arbitrage.  This is something that will end by tariffs or war, or both, and it's going to happen soon.  The US already put enormous tariffs on China steel to protect that industry.  Tariffs on everything else from China by every nation on earth is what comes next.  China knows this is coming, this is why they're trying to prop up domestic spending.
