The problem is that many ICO are made not qualitatively! Even if they do not scam. And when many do not think about quality, it is difficult to determine which product is a scam and which one is not.
Well I think it is getting easier by the day to discover scam ico's. There are so many scams around I stopped investing money in them since last summer (which was an excellent choice since last summer was ico heaven
). IF I'd actually buy anything now (I still do bounties but I'm not investing money/eth/btc) it would be ONLY when these things are ALL turned to green:- Low profile ICO (more room to growth) with a good plan.
- Low profile team that can be TRACED, that has actually proven something and doing something else but keeping their telegram alive
OR
- Low profile tech project with killer devs (they don't even need to be known/public/traceable) who are obviously producing at a high pace but don't care about marketing (yet).
You WANT to be part of the next XEM/PRL/ADA/... from day one and you don't want to be part of some 'revolutionizing some field with 40% pre-sale discount, ico will end after 6 stages with 80 million marketcap blah blah' ico/scam that MIGHT be pumped to x2-x5 once before it dies IF it even ever hits the exchanges...
