You invested in a ICO or IEO project at 1$ per token or coin and the price surge up to 3$ but because you see potential in the project you decide to hold and after few months the price goes down to 0.45$ and after four years and the token surge back to 3$, my question is why the wait? You hold a coin for years just to go back to it's ATH (All Time High) ? And most times majority of coins don't go back to their ATH ever again, what could you learn from this? Never ever hesitate to take profits, even if the project is the best ever, take profits, invest again when price is down because believe me, the price will surely go down
if humans are programmed to see the future won't we all be rich?
I think that this is due to the greed of some people to obtain greater profits, and that is why you find these people wasting a lot of selling opportunities for months and years in the hope that the price of the coin will increase for more than this, and in the end they found that the coin has dump, because the crypto market is volatile and you can't control it, everyone should set the goal of selling and when the coin reaches this goal, then does not hesitate to sell.
Developers of the cryptocurrency projects offer big profit because people want to have a big profit.
People want to do nothing and have a big profit

That is why now staking system is so popular when people receive reward just for holding tokens.
But different projects use different staking systems. Here is an article about different staking systems to know more about staking
