by 2009 it was clear - not only letting a single nation control the reserve currency afforded them tremendous advantage, it also put the global monetary system at great peril. The obvious choice was to either go back to gold standard; or to have a ledger NOT controlled by a single nation - an entity or not even an individual. While many attempted to solve this hard problem, the best design came from Satoshi aka bitcoin. The revelation, however, was - that simple ledger needed more energy to maintain itself than digging out all the gold. At the end - humans realized it wasn't about bitcoin or gold. It was the simple truth that if we build something - same amount of energy must be put aside to hold its value - value is half of everything
