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.
This is what I also imparted to my friend whom I influenced into investing in ICO. The very first thing I told them is the worst thing that can happen when investing in an ICO or even in coins already listed in the market. But really, ICOs today are so risky you have very small chance of not getting scammed or the ICO being a failure.
