This is the only thing I can say. If you see that Shiba Inu is still trending and you want to follow the trend then I would say that it's worth it but if you see or think that it is no longer in trend then I it's not worth it. Anyway, Up to you to decide and I think it's better of you prefer altcoins that are used by many people like or try ETH for example. Shiba Inu may be worth it but I think you have to wait for Bull run and the disadvantage of it is because it is a meme coin.
trend has switched over to L2 of ethereum, it's no more meme coin and meme coin in general are rarely having rally anyway. so I think it's can be said that these meme coins are done for, in term of having some massive rally. none one care about meme coin any more, utility are now essential that's the reason L2 become so popular.
