Does the amount of money raised in an ico determine the success of the project??
Is a necessity to do a fund raiser in order to start up a project??
Did satoshi nakamoto and vitalik also started a fund raised??
It does not necessarily determine the succes of the project but it can be a starting point for it.
it's not a necessity to raise funds in order to start up a project. Some projects already had the financial resources to start their project without needing to raise funds
Indeed there are those, projects that already have funds can usually start their projects quickly. But if the project does not have funds, of course they will do fundraising, namely ICO so that the projects they run can develop.
