I agree with your idea that trading crypto is not certain but it is very volatile and volatile fluctuations are very unpredictable, not to mention pumping, dump, and FOMO because if we are swept away In this crypto we will not have a chance to sell it to others and we will lose more money.
Even in Bitcoin it's also unpredictable no one even expected that we will go in this place in just short period of time. For investing in altcoin DYOR is very important if you want to make a sure entry buy coins only if there are events that can help the price up . Buy it as early as possible before the event come so you can sell it with profit I know many people already doing that kind of startegy use for trading they are searching for different source to check if there is event will happen and how big it is.
