You won't be hurting yourself and won't make a loss if you never sell your Shiba Inu. But the question is how long will you be able to hold them? If the value won't eventually recover again, i think that will hurt you the most because there is no chance to make profits from them. If you are investing in those high risk coins, think of its consequences, and not just the luck that it will bring once it reaches an all time high. So to be more assured that you won't be losing in the end, invest in bitcoin and other established coins as they won't just depend on hype or let's say luck.
Basically the idea is that people are saying shiba will not be something you can profit, but you won't hurt to lose some money... Makes zero sense to me, why would I throw money at a wall and hope that it sticks? If I feel like it will not profit me then I will not invest in anything, that is the way I invest, if I kept on investing on things that rarely made sense and just throw money away then I wouldn't have profited at all.
Some people are just giving it a shot because they want to get rich quick, they want to retire early, they want a shortcut to being wealthy and we all know that none of that will ever happen in a regular world, maybe a few lucky people but not everybody.
