Reason is simple:
It has been TWICE that china got burnt on BTC, selling as low as $3,900 last weekend, and as low at $4,100 today.
Every time, BTC showed strong resilience and systematically went back up in the $4,400
Lots of Chinese traders lots money, and WILL want to make this money back... spreading FUD and fake news on BTC.
Just be ready... hodl or trade... but it will happen again.
This happens when we heard humor that bitcoin banned in china,in order to discourage all chinese bitcoiner to not continue in trading,but this kind of critics and humor will not affected so much the current happen in the world of digital currency.co'z everything fake news they throw to bitcoin the more btc will popularize in the whole country and continue his legacy.
