Isn't it fascinating that cryptocurrency is the only "thing" that is of equal value in entire world?
I think personally that it is the first step that will be remembered as movement that will ultimately lead to uniting the whole world without borders and boundaries.
And yes cryptography is the future and it couldn't be better GDPR - privacy and security written in alpha code back in 2009 by Satoshi Nakamoto.
In the future, blockchain will run all of the application, network infrastructures, grids and will lead to completely autonomous self-sustaining society in which will humans participate with very little or no labor at all.
It won't be run on "primitive" way - such as is today, because this is stone age of crypto epoch - and we're all proud pioneers of that age.
