The question is, what happens when a coin skyrockets to a price satisfactory to every investor? Definitely, more than 90% of the investors will begin to withdraw in order to make profit. This is one of the factors that has caused the drop in price of Bitcoin. It is called the correction period and until the investors reduce the withdrawal and reach a stage where another set of investments are made which surpasses the withdrawal, the bear market will continue.
I would argue that 90% of the investors would begin to withdraw in the case you described in the first sentence. Most of the current investors are not traders and they are not looking for profits in a short term. The main factor which caused the drop in price was not the selling by most investors, but rather the selling by a few but very wealthy ones, who are called whales. And we will continue seeing the bearish trends every time the price rises significantly until they will run out of their stashes, in other words, until all the coins they have will be distributed among millions of long-term investors.
it seems they know very well what to do, with the current conditions, indeed i think the whales are planning something to get big profits. technically the bearish trend still continues
