Well, it is because some people are afraid to gamble. Those who buys when the price of crypto is increasing, are those who cannot afford investing and waiting for years. There do tend to wait for the movement before investing to something because in such way, the direction will lessen the risk. But ofcourse, the profit will still be bigger if you invested at the "bottom" but these people are more concerned of lesser risk than bigger profit, which I think is not wrong. We just have our own ways in order to come up with profit in this industry.
