When the enigmatic, possibly nonexistent Satoshi Nakamoto minted the world’s first cryptocurrency in 2009, the plan was to create a decentralized payments platform that would revolutionize the way we buy and sell everything.

The point of Bitcoin, according to Nakamoto’s founding white paper, was to enable instantaneous, borderless transactions without the high fees or foreign exchange barriers that exist today.
