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??
Not really, i have seen some success projects but they didn't raised too much funds, only about 1 million USD.
to starting a project, of course funds are needed to build it. But if you already have enough funds, it won't be necessary to raise more funds.
I think Ethereum was running ICO, selling their ETH at certain rate.
