Many people have become greedy lately. That's why ICO price often don't make sense. I see some ICO projects are seeking only quick profit. I am glad that Mr Butterin said that, it's good call for us.
Greedy to the point that they risk all their life savings just because they want to make quick bucks and this is the main reason why so many of them panic easily and sell for loss once it starts dropping hard. It is really good he mentioned something like this, and if people are very smart enough, investing what they cannot afford to lose is like playing with the Tiger's tail. Hopefully, people get to listen.
