This is why managing your time of hold is far more important than just holding on for the ride, for example:

$5000 in, coin goes up 2x, you cash out you now have $10,000, reinvest this, coin goes up 2x you now have $20,000, you are more likely to get 2x twice in a year than you are 4x over a whole year just holding for 12 months.

Sure you could get unlucky, sell for 2x then 1 month later it's up 3-4x, but it's a bit optimistic to hope something will just keep on going up, also how quickly they go up gives an idea too, 100% in a week is viewed a lot different compared to 100% in 2 months for me, the quicker it goes up, the quicker it comes down.

It's better to compound multiple growths over and over than to just hold for 1 large growth, safer in my eyes too.
