of all the listed suggestions I most confess having a solid use-case is the most important feature in a project. It beats me hollow when I see projects with zero or no use-case propagating in the crypto space. No use case equals to know the demand and this further implies no value. Hence its pivotal for a project to have a good usecase in order to ensure value.
Couldn't possibly agree with you more. There are tons of useless projects out there with 0 use cases at all. They simply steal code from other projects, and claim it as their own under some kind of disguise, some don't hide it at all.
One of the few projects I know who's been working their asses off is Blocknet. These guys made the first DEX, coded everything from scratch, yet it seems like nobody cares? I don't get it.
Look at TRON, just as an example. Did an ICO with empty promises, recieved millions in funding, pumped like crazy, and dumped back down again, yet it's STILL a top 20 coin, based on what? NOTHING.
As an investor it's really hard to know which projects is worth your time, and which aren't. Blocknet is pretty solid though, among other old projects who had the time to develop their own products.
