I still very much beleieve in ICO, and my best pick for 2018 would be Typerium, it has showed great commitment so far and their bounty is amazing, i would still reccomend it to people as they just started their pre sale 2 days back. www.typerium.io
What i believe in is more of spreading risks, i do multiple bounties just so to gain and eliminate the risk of the scams out there, it really all comes down to how well the project is build up, the product and good bounty manager. I have down a project i thought was worthwhile but after ICO,it all came crumbling down, good example is Cibus.
