Right now ICO's are so hot that I am just jumping from one to the other. My goal is to accumulate as much Bitcoin as I can because it will be $13800 by March 2018 and this summer is the summer of ICO's according to Clif.
Also these ICO's can still fail because all they are only a white paper and a website as far as anyone knows. I prefer to hold my wealth longterm in Bitcoin.
