One scam-ish thing to look out for with ICOs is their teams. I have a pretty respectable linkedin profile, and I have some items pertaining to Cryptocurrencies and Blockchain in my list of skills / interests. I have had random people add my linked in with what looks to be well made, but fake profiles, offering me a spot on their ICO development team just so they can paste my face on their whitepaper hosting site. I went to their site, and it had a bunch of other dumb saps they conned into it on there. These guys are going to get reamed so hard when government regulation (the good kind) comes down on them, and the guy who started it will be laughing all the way back to St. Petersburg National Bank lol.
