Description
An ICO is nowadays seen as a valuable option to raise funds for a certain endeavor. In addition, is it seen as an alternative for crowdfunding / crowdinvesting. You think that won't work? Just remind yourself of stupid use cases like dogecoin that got funded heavily. http://dogecoin.com So why not try it and raise 100 million €, it seems to be easier as it sounds.
