First, some background. Bitcoin is often (falsely I might add) criticized for being centralized in China. This criticism includes the fact that China "owns" most of the hashrate (often cited at 70%+) and therefore controls bitcoin with the threat of shutting down the network or confiscation of coins. While this FUD is easily disputed if you put in the time to do the research, the reality is that it is 10x easier to simply spread fake news.
Presently, Mining moving out of China is now being labelled as bad for Bitcoin even though it was previously used to accuse bitcoin of being a China coin. As usual, FUD and short term price are often noise. Focus on the signal, Bitcoin is distributed ledger that ensures 21 million coins, immutability and uncensorship resistance. As long as the fundamentals continue to grow, Bitcoin is provably stronger.
