What percent of ICO's are scam, on your opinion?

Apparently more than half of ICOs fail within 4 months.

Just came across this in my Twitter feed: https://www.coindesk.com/over-half-of-icos-fail-within-4-months-suggests-us-study/

Basically, they use social network activity as a metric. Those ICOs that don't have any activity after 4 months are considered dead.

I think scammers have just become bigger at the moment. So, I'd like to wish everyone better look and do not rush. No one is immune, but still. Warning, never will be superfluous. Good luck to all

We need to differentiate between genuine failures (due to market conditions.etc) and pure scams. My guess is that the latter category may account for anywhere from 20% to 30% of the recent ICOs.

About 80% of ICO is a scam. So do your research before you invest in an ICO!
There is an ICO called MediBit. I liked their concept and how they are differentiating themselves from other similar ICOs by working on forming the alliance with hospitals, clinics, and pharmacies. While others focus only on their platform development, they seem to consider the feasibility in real life situation and field test.
