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.
Trading is those who have time to monitor their investments, unlike stock trading we can just wait when the company we invested with have news or development in crypto we need to take advantage the time they are popular since after that it may not going to set new high price, always monitor snd never be greedy in trading.
