I don't see too many good ICO's right now, also when you consider the market is going down I don't think it's a good time to invest in ICO's. Unless you don't find a very good one just wait for the right time/project to come.
The point is there are less ICo than a year ago just because the market is turning at the mature phase and you can't just create a silly ICO with stolen Whitepapers and get money
Nowadays you gotta work really hard
