If bitcoin decreases, I have to keep holding it for a long time so I can get it. Because if I will not keep it for a long time, then it is useless because you can not profit well if you buy bitcoin at a high price and then if it will decrease, I can not sell it at a high price of course. Buy bitcoin is cheaper because by doing this you can make more money and I'm sure a lot of whales do it also riding it and generating buying flow.
