After 2017 max ICO profits, ICO has since then been a high target for scammers but alas ICO will still survive on the long run ,bitorrent and fetch.ai has proven that, many investors are now getting smart and extremely more careful ,its really a good thing ,before we know it the scam rate will get lower and scammers won't make a dime from ICO anymore. I think action speaks more than words,no one wants to lose money to scam projects anymore so they are forced to learn how to spot good projects to invest in. Warning doesn't work but investors losing money does makes them learn.
Most of the investors now are really wise so far, after all what happened in 2018 about the ICO projects.
Because of that incidents happened when 2019 came in, as time goes by IEO become popular little by little where most of
the investors and bounty hunters are awaken their hopes again and back their trust once more in participating in the new projects
