You want to organize the worlds information and build a search engine. Okay, you create a google coin. You issue 21 Million coins.
As soon as you announce it people are going to buy in and you will in a period of a few months become a billionaire. With no product. Just an idea.
And then you get to dump your shares on the "investors" and you get to be a billionaire.
There is no incentive to further develop your idea.
Look at what happened to ICP. The VCs got in at 3 cents a coin. Each coin shot up to $750 per coin. Then the VCs dumped it on the retail noobs making a lot of money with absolutely no working product.
