^^ This. Looks like that big buy was no whale accumulator, but a/many shorter(s) closing their positions for low slippage.
Potentailly bearish in reality as 11k was waaay too high for the market to make any significant move down.
Now at 5.5k, there are not enough shorts to squeeze IMO.

EDIT : My numbers are wrong 9.2k shorts dropped to 5.8k. Misread chart
