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.
