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.
Yeah invest only to the amount that you can afford to loose and don't be greedy. Let's all remember that at any time price can go to zero and we had no guarantee that we can get profits in here. This is a full of speculation about the price with no real identity.
