I just started with this so maybe it turns out I'm completely wrong here... but what I looked for was the following:
*Good project idea
*Enough people intrested in the project
*Good team
*Good bounty manager
*Enough funds distrubuted to bounty hunters
So basicly the same stuff I look for in an ICO except for the bounty part.
I agree with you. If the ICO are good, of course usually have a good bounty program too. The most important thing is to make sure the project is not a SCAM
