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
It is not going to hurt if you keep holding your shiba inu, anything is possible within the crypto space. Tomorrow it is possible that shiba inu ATH can go over that of doge, but also keep in mind that it can also not go well. But, patients is what you need because you may invest with shiba inu the only amount which is affordable to you on the event of shiba inu gets dumped and delisted from exchanges, so you need to be patience until something happens with shiba inu.
I agree about investing the amount which will not hurt you on losing it but the question is why shiba inu and not any other coin. Because, like shiba inu, we are having at least 100s of similar coins with potential to rise in future. Now, if I invest my small amount into all 100 coins then that will definitely hurt me if I happen to lose 50% of them.
