As physical currency around the world is increasingly phased out, the era where "cash is king" seems to be coming to an end. Countries like India and South Korea have chosen to limit access to physical money by law, and others are beginning to test digital blockchains for their central banks.

Although this transition may feel like a natural progression into the digital age, the real motivation to go cashless is downright sinister.

The unprecedented collusion between governments and central banks that occurred in 2008 led to bailouts, zero percent interest rates and quantitative easing on a scale never before seen in history. Those decisions, which were made under duress and in closed-door meetings, set the stage for this inevitable demise of paper money.
