Because people is now making ridiculous projects over the blockchain, and they do not even understand why blockchain means, they are just using that word because it has a lot of potential to do marketing.
There are some projects like Sex on the blockchain from a sexshop ico, i do know what has been about that ico, i thought that they rised more than one million dollars from this ridiculous idea.
And there would still be some more projects like this, they are like a plague . But if they are really good projects, then i dont see why they can not develop an idea over the blockchain, it is helping everybody in here at any way.
