Crypto space is lacking real use case presently and devs are just repeating same old projects over and over, sooner or later no single investor will have interest in new projects, not until they come up with something fresh and new
I totally agree with this.
And I believe its not something devs are not aware of. At least not ones who work in superior projects like ethereum, eos and etc.
Their goal is to unite a lot of different (or quite similar) projects with one mainnet so they could together make something bigger, like a giant system of use cases and etc.
