So thinking about it that way encourages me that there is hope for a better tomorrow, for improvement of the human condition and societal organization. Perhaps cryptocurrencies will be the sword that finally strikes a mighty blow at the root of centralized power: control over money....
Yes, it could certainly be.
For sure, in numerous third world counties in which such dire straits and corruption exist that there is no way Paypal could get established there, and hence, Amazon or Ebay cannot exist there.
Beyond those situations, where a separate private currency has obvious advantages (yes I am talking about someone in the US trading directly with someone in Kenya, etc) it is not so clear.
Would the emergence of a crypto currency in the USA say to the extent of 10% of paypal transactions cause fundamental social or political change? If so, how and what?
