If I am asked about the winner of this year's crypto currency then I will see the winner of this crypto currency technologically. Technology means ethereum wins. Although ethereum does not occupy the top position but ethereum is technologically superior. Ethereum does not occupy a top position because it loses populatity and public trust in bitcoin. But I am sure that for the long term this ethereum will be very potential and can become a crypto currency leader. All just waiting for the right time. Technologically, ethereum is almost perfect because it has almost no defects in blockchain technology. And ethereum proved its benefits significantly. Ethereum is now nicknamed the king of ICO.
