Normally I do not invest into stuff that I can't understand the concept myself, I do not like the features that looks like they are not needed in crypto world right now, however I just did a silly investment myself. I bought a cryptokitty. It is not an ICO I know but it showed my flaw that if I like something enough, I can invest into it without even caring about whitepapers or team behind it and all that.
I didn't even know who was the team behind it, I just know the company name dapper labs or something. Which can translate into ICO and the new coins that's coming up, I can literally invest into something that I want, all great inventions come from a need, if I want something, if I need something and I go out and build a platform for that need, if that's needed by enough other people than you can apparently get your ICO to the top. Just work towards what people need.
