I do not think a whale selling would crash that much. 2.4 billion dollars is nothing in the daily volume of bitcoin, while it would definitely drop it a bit, we do have enough buyers to cover that in normal days. It was just a bad period where the rates weren't cut, so it was normal for the price to crash.

Let's see that whale try to sell all 150k bitcoins in a single day during the bull market, I guarantee you that it would be all sold in a day and we would not drop much, because during bull periods , we go up by 10-20%+ anyways, it would just level that and not more. That is why these news never make sense to me, it's just a normal situation without any big problems ever, it is not that complicated and never was.
