Always bear in your mind if you invest in ICO today, "HOPE FOR THE BEST BUT ALWAYS PREPARE FOR WORST", to expect best result of your investment in ICO all the while being prepared with options in case it is the worst one possible, there is a few investor in ICO today being fooled, beacause they don't prepare for the worst.
Not that few investors only but there were many of it. This is why I never invested to an ICO because they can't fulfill their promises in the long run and besides supporting bitcoin with few alts that are legit in the circulation would be for the best. ICOs today are just money makers and including the investors it's hard to choose what will be the legit ones and the fake ones but even the most legit one with your first impression starts to become weird if you don't really have full knowledge on the developers.
