The main word in your sentence is "if". Let me put it to you this way: if you went to 100 angel investors and pitched them this idea, how much money do you think you would raise? Probably 0, or if some of them liked you, they would take a 50-100k punt. But you would never ever get 35M... without anything but a 350 dollars site. If they manage to build the platform, if it works, if it gets adopted, if it generates revenue for everybody involved, then you have a business. But, as you can see, there are alot of iffs.
Think about it, in the real world you first have to build something before it has any real value. An ideea is worth nothing...
Let me give you annother one: TokenCard TKN has a market cap of 65M and, not only have they done nothing, not only have they not delivered on their roadmap, but there are currently other similar products that work perfect and therefore nobody even needs it at this point. Yes, they promise some really nice tech, but it's just promises. So, I ask you, what is going on?
