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.
I don't think ico scam will ever go away.. as people or investors get smarter you should be aware that there are also new investors coming into the market daily.. plus scammers are also working on new formats to defraud investors
