It won't hurt to have 100,000 shiba inu coin in your wallet you know, I'm saying this because I used to have 1,000,000 doge coin in my wallet but got tired of holding it and sold, we both know how much that it today so we can't say if shiba can make its way to where doge coin is right now, it won't hurt to have some in holding
Even you are making sense, there will be no guarantee for shiba inu to follow dogecoins after some years. It means the amount that I am investing right now into shiba inu my turn into zero over the years but if I invest that same money into bitcoin then it will definitely will grow at least 10x. That is the basic difference I am seeing right now even the money I am going to invest into shiba may not be hurting me.
Dogecoin was a first memecoin hence it became successful even after some years; this may not be true for all other memecoins including shiba inu.
Have nothing to expect much about this coin right now. It was their hypes getting over and only another hypes could help them out or else, they just remain in their position forever.
This is how to see about investing hyped projects, they are clearly not sustainable and it only appears shortly then just fall down. It is a need for OP to decide to sell them while it was still at a good price otherwise, regrets are to be coming next. They are not hopeless projects anyway, but their future seems uncertain.
