What the world truly need is more empowered people and empowerment comes from knowledge. Knowledge are made of bits of information linked and accessed in a meaningful way. Cryptocurrencies are just that, information linked and accessed in a meaningful way.
People who mine cryptocurrencies are indirectly stating they want power to shift away from governments and back to the individuals. Not only are they stating it but they are making it happen whether they realize it or not.
People who are spreading empowering knowledge are doing the same as those who are mining cryptocurrencies but in a much more fundamental manner.
