Well, because in crypto there are two types of people who want investments.
Those are crypto holders, they want the price will pump up to see their profit and immediately cut it off once they had. On the other hand, those who want to invest, are waiting when there is a correction in the market or when it will dump. Not all are happy to see that there is an always all-time high in the market, that is why there is no continuous growth of the crypto price, it should be volatile by its nature.
