It's worth the investment at early inception but right now it's a scary thing to invest with. They may have a chain that is linked to them namely Shibarium but there's still no assurance it would increase the value of it. There's a chance it won't. Expect more from the burning that they do, when the total number of coins gets lower then it could be for the better of their investors who have put their trust since Day 1. Do remember, this is still a memecoin and I suggest to stay away from it, but due to it's popularity it became one of the good choice when we are talking about memecoins only.
But for me, Shiba Inu is different from other meme coins. I'd see this Shibarium is one of their developing strategy to help Siha Inu be recognized more but it was been receiving negative views which actually affect the trust of the investors. Because as we can imagine, if Shiba is another shitcoins, we are supposed not to see it now in the market having that value. But fortunately, it was still one of the top 20 in the CMC which means that the demand is still high and has strong support from the community.
Of course, invest in the project that we trust most, we can't put Shiba Inu on our list if we have doubts.
