The high rate of worthless coins are now at alarming rate as we have experience a very difficult time in distinguishing between Good coins and shit coins. Getting into Campaigns with the aims of getting a good coin for the future, all we can get is some worthless coins into the wallet. Those worthless coins or as i called them valueless Altcoins.
What will you do to your worthless Altcoins in your wallet?
I think there could be some kind of probability that any of these worthless or valueless coin/token as you put, may bounce back, because most of these coins/token you termed worthlessness or valueless, has every tendency to join the meanstream altcoins especially if the project team decide to do some kind of remarking or may be rebranding of these coin/token.
Obviously, it is important to maintain a "Hold" on these coin/token for some time and see how it goes on the long run.
I agree with your viewpoint, I do the same. I also think that if a project fails completely or is a scam, those coins will never recover and acquire some value.
