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.
Without a doubt investing in shiba inu on its earliest stages was a good idea, however there were so many meme coins being created each day that it was impossible for anyone to know that shiba inu was going to be one of the meme coins that skyrocketed, but since it happened once people are assuming that it can happen a second time, and I think there is a possibility this is the case, but with the market cap of shiba inu being so high the profits are not going to be as good as they were in the past.
