You should build the project first and then community will form on its own if the project is worthy. Otherwise, if you're building community before project, that's just a scam, you are making promises to people so that they would invest in your token, and then you fail to fulfill your promises yet take the money.

Satoshi didn't build community and ask for money to make Bitcoin. Why crypto devs think that they are better than Satoshi and ask for money for development in the form of ICO?
