Just take this as a learning experience. You should always bear in your mind that most probably 90 percent of ICOs will fail. If you are to invest in an ICO have some thorough research first. When I participate in a bounty campaign, I'll make sure to check first the developing team behind the project and how much funding they have already received and of course, ratings on ICO websites somehow matter. We are definitely well past the point of gaining through randomly throwing our money from the bag for these crowdsales.
