its not risky to hold a sh*tcoin as long as you dont invest money to obtain it . i myself have a lot of shitcoin and i only got them on airdrops and bounties but i will still continue to hodl them even thier prices right now are dumping and seem to be dying .
What you wrote indicates that you do not know what you have. In other words, it is a lottery for you and you have no idea what these projects can achieve.
yes holding them will not make you rich but atleast you can earn something whenever thier prices will sky rocket . if you are lucky enough , you can possibly get rich on them as long as you constantly join tons of bounties and airdrops .
Keeping coins will never make you rich - it's how to win the lottery. First of all, you have to learn how to invest and, above all, learn how to invest in what you understand!
When you understand what you are getting into - you will be close to victory.
