I don't know if there are others that uses SHitcoin for long term holding ? what I do know is that others that keeps those shitcoins in their folio are the one who was being trapped and decided to keep them instead of selling in super low prices.
because instead of being complete loser they are praying that one day those coins will still have value(hoping really bad)
If someone buy certain shitcoins then obviously they will wait until next Bull run because if they sell these coins in less price then they will be in loss but they are in hope that one day their coins will increase in price and will show as a coin full of profit.
I think that selling at lower or no price is a bad choice because if your coins are useless and you keep it for longer time then there is a possibility of attaining higher worth in future but if you don't value shitcoins then you will loss your money forever.
There are numerous people who become moneyed by holding shitcoins because they don't loss loss hope but they still consider themselves lucky and finally they get what they deserve.
