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.
I think this warning is really important. In addition to these, I can clearly say that, people should hope for the best but prepare for the best for also their all kind of bitcoin and altcoin investments too.
