Lot of coins even went to zero at the bearish trend but still people holding those coisn with the hope of they can make lot of profits when they bump.There are some altcoins are worth to invest but we have 2000+ altcoins just to make more richer the people who were created those shitcoin not for ourselves so the people need to wakeup and start investing on the bitcoin.
if the coin reaches to zero then that is already considered dead and theres no point of keeping them . but if the coin do not have a value then we should hodl them because they might not be listed yet . your also right , there are many alts out there but they are only built for pump and dump business without real world usage at all . we must not support those kind of coins because they are not benificial in the long run . we'd better go on bitcoins and other well known alts like eth , bch , xrp and so on ...
I am just holding some of the coins with no value yet for almost a year now,and lost every hope had on those coins even they are released by the good project members so which means when the project team had enough profits they are not going to care much about the investors so the people investing on the ICOs are really just doing gambling with odds of winning very less.
