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.
