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
exactly how it is in real world
moreover, if you are already invested in like 100 different shitcoins you are much more likely to be aware if one of any shitcoins is blowing up right now (just because you will be monitoring all social media and stuff)
