Other people do that they hold they sell their bitcoin now and they waiting for another dumping which is a good idea that will gives you more profit. But it will also cause to you to lose profit let say you sell all your bitcoin and the price is rise so you lose it , what ever you do a decision they have consequences so make a research first before you do that like selling or holding this coin.
facts, i didn't really need money back in 2016-2017, and i had some bitcoin, and after a small profit, i exchanged it to FIAT, and bitcoin skyrocketed and i regret doing that, it's more than 30k now and i sold them at 2100$, now i would rather lose everything hoping for bitcoin to go up than sell and just take that small profit people are searching for.
