Hi,
1. The project receives the necessary amount of investment at the beginning, when the team's enthusiasm is still in full swing, and they are ready to tear and throw.
2.Startup is no longer required to actively seek out investors, conduct numerous rounds and presentations of the project in order to interest - it is enough to organize ICO.
3.Investors are interested in participating in ICO, as according to statistics 80% of projects give growth of 2x or more. As a rule, when a coin / token hits the exchange, it trades at a higher price.
4. High collection speed (some examples: BAT - 35 million dollars for 30 seconds, Bancor - 150 million dollars for 6 hours).
5. Automatical process of collecting funds and sending tokens in response.

Something like that.
