The Shiba still have a lot of supporters and have a good team that still develop the project, if they can find more use of the Shiba or if some company starts accepting Shiba I think it will pump more. In regards with Elon Musk, we shouldn't be surprise that he doesn't own Shiba since he supports Doge it's like supporting your enemy and he is really focusing on improving Dogecoin.
Shiba inu is a parody of dogecoin but i think this meme coin is way better than dogecoin itself. And to think that Elon does not owned it, its definitely a good thing as its less likely to have the same future with dogecoin.
However, considering that they started as meme coins would not be a good option to invest in Shiba inu because its future is still very uncertain. It might be very profitable at this moment, but who knows if a heavy price correction will soon to hit the market, its value will not recover anymore. So investing in Shiba inu needs to be more cautious as its only good for nothing in the end. I suggest to focus more on solid coins like bitcoin and ethereum as they have brighter future than Shiba inu.
