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 preparing for the worst in any investment is one of the reasons why people do not usually have a set out plan even before investing. However, to me, it is not even about expecting the worst; it is about trying to minimize the risk by investing in a quality ICO, but at the same time not investing what you cannot afford to lose.
That is always a smart way to go about any investment and even if the worst happens, you will know it must have been as a result of some factors beyond what one could have imagined, but would not shake you much since you did not get greedy in the first place.
