Ethereum has yet to prove itself !! ICO's are using ETH blockchain the cryptokitties have boomed it and think of it as a warm up rather than the end of it . Smart Contracts can and will be used in different industries such as housing and anything related to economics.Then imagine what happens when businesses start to use blockchain as a way of enhanced security . No more censorship and authority regulations could hold people down , well for many it would easen their lives and give them space to grow as these laws make it very hard to do something at all .
