This may sound funny but that is the reality. why?
Though the title says it all, you know China was the once the safe haven for bitcoin and bitcoiners.
Well, China is still safe for Bitcoin and Bit-coiners, but unfortunately it can be unsafe for them anytime in future. The Chinese government officials might did that to alarm the crypto users that anything could happen in their country.
Then, China started doing something to hurt the bitcoin and cryptocurrency in-general from banning ICOs to cryptocurrency exchanges and now they are after bitcoin miners, again.
Yeah, that banning of some well-known cryptocurrency exchanges was a really bad decision by Chinese government as that affected the whole crypto-world to some extent, but I highly doubt that was a drama to make whale investors and holders sell their Bitcoins for cheaper.
Although, I am not really sure that they're good or bad for Bitcoins, but I think that what they did was a really amazing thing at that time, and just because of their ban the Bitcoin's value increased to a new level. It went from $2200 to $18000 under 3 months and many of the investors made huge profits in that period.
