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.
Even with Dogecoin not having any use case, see how long it has survived the market ups and downs over the years and still here. I have never invested in Dogecoin though but I believe from what the subject question asked, Shiba Inu has a better advantage of investment than Dogecoin all you need to do is compare bot projects and see and I also believe it will be here for a longer time.
