I guess this is a strange thing to question. Neblio is a platform, similar to quite a few other platforms. They all share the same utility. Are you questioning the use cases for Lisk, Stratis, Neo, ethereum? Yes, there are a lot of them, but im not so sure that's a bad thing. We are talking about technology that is about to rapidly spread across the globe. If you think there isnt enough room for the existing platforms to all thrive and carve out their own users and markets then I disagree. Quite frankly, I think there's room for a few more. Just look at any industry and see how many successful multimillion/multibillion different companies exist within them. This is just the beginning and still and I dont think the market is oversaturated.
Also, I think Neblio is smart in targeting existing businesses and their jump to blockchain. While all platforms are more than receptive to this, there is definitely going to be a huge market for these types of projects. A lot of companies will begin to find use cases for blockchains within their business. Platforms which help the development of these applications in the most seamless way possible will thrive.
I was little wary of another platform project back when Neblio started its original rise in popularity, but I have become much more open to the idea that we are seeing just the beginning here.
So tl;dr "because blockchain hype". Problem is that there's a ton of new blockchains in development.
