To be honest I am not a big fan of ICO because what I have seen and experienced is that people start a venture with lot of energy and positive outlook. They even offer Airdrops and Bounties. After sometime when token/coin sale goal is reached, they would either slow stop responding to queries or will wind up and go away. What's left behind are frustrations and loss of a common man. However there are some good one out there too which deliver as promised, we just got to be careful dealing with ICO's.
