Interesting paper, but whether the early cooperation was necessarily altruistic in nature remains a mystery to me. The highly centralized structure which transpired to make Bitcoin popular and regarded as secure raises suspicion about its legitimacy and true intentions, in my mind. Over a decade later, digital currencies have become much more palatable and even attractive to people, that there's even talk of government-backed DC's, and this resulting Overton window shift has significant implications for individual freedom and society.
