This is one problem with crypto in general. You have people new to investing combined with somewhat unrealistic expectations. If all investments rose 10x within a year we'd all be rich (but then there'd be crazy inflation, but that's a different discussion).
If you can get a return over 10% you're doing OK. Could you have made more money elsewhere? Sure. But there's a difference between losing money and not making as much as you could have.
A safe investor won't keep all of their money in one crypto. In fact, they won't invest all their money in crypto. Sure, some people had overnight success because they did. But good portfolios are diversified so you have good performances to offset losses. Imagine that someone finds a better cheaper way of handing these ledgers and transactions that doesn't involve blockchain at all. Overnight, all crypto could crash. It could literally be worthless.
Hope for the best, plan for the worst.
