If you need a quick buck, dump them. You can always buy more when you recover financially.
But i always kept my shitcoins in the past. 9 out of 10 would plummet to death, but that 1 that made it, made it big
he said a few years, and maybe he has been holding it back from 2017, I looked at the list of coins in 2017 when the price was very high, so it would be difficult to recover the loss some coins lost more than 90%. its a hard decision too sell or hold it.
In the next altcoin bull run like we had in 2017 you think these alts wont recover to ATH's? Not even 25 to 50% recovery in the next bull run?
