Neither of these projects have a valid use-case. They are meme-coins. Speculative gambling at best.
I’d be lying if I said I never owned any. But just a few dollars here or there. These aren’t serious projects for real investors. And they probably won’t be around in the next 10 years.
Both are really meme coins, but I think SHIB is more better than Dogecoin in my own view only. Although, Dogecoin was one of the pioneering altcoins here in crypto space, but its price value goes up only when Elon Musk promoted it at twitter, same goes with Shiba but even is like that Shiba Inu I guess has a lot of use compared to Dogecoin.
