Bitcoin is so powerful that the very word actually refers to two things.
Bitcoin with a capital ‘B’ refers to a distributed ledger, or blockchain, on which everyone’s transactions are recorded. Decentralized means that no single entity is in control, giving rise to a peer-to-peer electronic cash system that is secure, transparent and truly global.
bitcoin with a small ‘b’ refers to the digital asset, the one that is fast replacing gold as the world’s favourite store of value. And it isn’t hard to see why. Bitcoin’s superior monetary policy means that new coins come into existence at a fixed, predictable rate, and there’ll only ever be 21 million bitcoins. As for as a scarce, inflation-resistant assets go, Bitcoin tops the chart with ease.
