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.
Many investors of ICO who fell victims with scam ICO has learned their lesson but this does not mean they lost faith in any ICOs. ICO will survive because not all of them are scams anyway. Legitimate projects or ICO companies have been tagged because of these unscrupolous scammers. The beat thing to do now is just being careful and study your bet. Research first the company you want to trust your investment. Anyway it is your responsibility and mistake if you fell victim to them.
