I share your concerns about governments wanting to control cryptocurrencies, but I have to disagree that they ever will. Too many crypto's are based on anonymity and decentralization principles. It maybe possible to control some, but never all.
Thanks for the article! I always love to read about automation and it's potential for the future.
But if they introduce a world crypto token that you have to use to purchase anything with they will still control the wealth as you will have to convert your currency into their banking token so in the end the banks will win.
