Remember the dumpers are saying about he was aiming to get a high price to sell them all as soon as possible. That means he will be trying to make a regular dump to the market. I think that he sold a lot of amount of bitcoin when bitcoin reaches its peak around 20k. But i gonna thinking if he will be waiting for another recover again. 166k bitcoin and that a really huge amount. I'm not sure about the dump is over. But just waiting for the final result what will be happening with the rest.
