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?
