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 know that with the appearance of the IEO, investors will be more secure when buying token of the project. This will also be a new trend for 2019 and ICO will soon be removed from the crypto market because the system is not transparent and accused of negative news.
The IEO will help us have a new playground and investors will have a great source of income coming from successful IEO projects.
