We all are well aware of ICO
frauds.
I use the strategy to start with a whitepaper, see team member details and the roadmap.
What strategy you adopt to make sure the ICO is not a scam/fraud?
In my opinion that should be the minimum necessary to invest in an ico, but most people do not even bother to do that much which is one of the reasons of why we see so many people getting scammed all the time in the forum, people only care about getting profits and in their search for profits they ignore all the warning sings that a coin is not what it looks like.
