This technology being bitcoin or something else is here to stay, it won't go away, and it will change the world.
In 5 years, people will wonder how the hell were they living before block-chain, just like they do now with the internet and the smartphone.
Facebook, google, and many more centralized solutions in the form they exist now will, in time, seem so absurd, outdated, and illogical...
This tech will change finance, internet, the way we pay, communicate, do business, consume art and entertainment, travel, and even change the way governments operate.
