1. Lethargy during a sideways market
2. Disregarding your strategy
3. Chasing somebody elses dream
4. Believing somebody elses FUD
5. Using money that you shouldnt be
6. Failing to properly do a self risk analysis before investing
If you can cope with these dangers then this type of investment will do well for you. This is a hands-off, long term method of investing. DYOR, find good coins with bright futures, buy and hold. Dont worry about the daily percentages
what you say is true, the danger of trading always focuses on the percentage of daily ups and downs, in my opinion it fosters tension in the brain (panic), then invests that we don't know in the future with using money that you shouldn't be? but if the money belongs to him then it is fine in my opinion.
