Many people look at them as coins, while we should see it as our future technology. The technology of the .com not only stayed, but controls our lives today. The blockchain will do to banks, social media, entertainment, aviation, and global shipping similar to what the internet did to newspapers/phone book, what the email did to the letter, Netflix did to blockbuster, and what amazon is doing to big box stores.
However, there are too many useless of them that eventually will die away and only some with real applications will survive, and hope #steemit will be one! It just already feels so good when you see nobody runs your social media platform, have full authority to your contents, or feeds you as they wish! We need the same decentralized technologies in other areas to be implemented!
