There's no need to waste time looking for all of them. I can tell it just by looking at the website and its presentation. If the website looks like it is made by a 5 year old with tweaked WordPress themes, then you know what that means. But if its quite good then I dug deeper into each of the member's profile for red flags. If there's none getting caught red handed, I still don't invest in their ICOs without getting enlisted in exchanges first.

I am a simple dude. I find any legitimate tokens on exchanges, I trade.
