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?
To avoid ICO scam, I chose an ICO that gets a good rating on some ICO Rating Portal like icobench, icotracker, tokenmarket etc. Also, see from partnership and media publication.
It's just my opinion. CMIIW
