I invest in ICO because the world is rule by idea. Old idea has already been max out in terms of their potential. If we are going to enjoy better living we must do away with the old and embrace the new.
But not all good ideas will be done by honest people. The chance to lose your money with ICO is higher since there is no way to protect investors money. It's based on trust only!
To define all this maybe we should look for the background of the project and maybe we shouldn't hold there tokens for more longer days since ICO coins are not mean't to be holded unlike bitcoins since the some of the developer are just hyping and manipulating for their own gains.
