I don’t think Satoshi Nakamoto and vitalik did any fund raising for bitcoin, cause if they did,  then he will have to show himself off. And I’ve never heard any story that says they did any fundraising. And his main intention was just to create a tool for peer-to-peer transaction. The ones you see now are just doing business, that’s why they will abandon their projects.

Majority of them are just looking for money and not after building the project. That’s why you will hardly see any unique project these days, they just copy what others have done already. Most of them wants to make money and that’s all they after, and nothing else. When it is not working they will run away with the little they have got.
