Understand what's going on, and hit them where it hurts.

This is (obviously) a coordinated dump. This is not retail investors selling a bit of BTC, but an enormous amount of Bitcoin flowing from coordinating institutions. The BTC is likely borrowed and immediately sold to cause a panic.

But they have to get that BTC back in order to cover their asses. Buy now, and disrupt the strategy.

The price will rebound, and the institutions are going to have even more BTC if you capitulate now.
