This is so obvious, in my opinion it seems China are just using this time or reason to re enter with a lower price. Its always business matter. Of course they knew that bull season and crypto market still on good mood, and they decided to jump in. Why? Very simple create fud and let the price go down, of course they will wanted to buy a cheap price rather than jump in with an expensive value now.
Michael Saylor is honest and announced they bought at 43k level. But China is not playing fair, needed to exploit the market through banning crypto and probably will unban once they already bought back their bags.
