Bitcoin

Bitcoin is a decentralized digital currency launched in January 2009 by the pseudonymous Satoshi Nakamoto. It runs on a peer-to-peer network of computers that settles transactions in blocks roughly every 10 minutes, without banks, payment processors, or governments. Its supply is capped at 21 million coins, a limit enforced by every node that validates the network's rules.

Why it matters

Bitcoin is the first asset in history whose scarcity is enforced by software rather than by geology or government policy. New coins enter circulation through mining, and the issuance rate is cut in half every 210,000 blocks, roughly every four years. This schedule is public, auditable, and has never been altered since launch.

Over 16 years the network has grown from a cryptography mailing list experiment into an asset held by public companies, exchange-traded funds, and at least one nation state. Its security budget, the electricity and hardware miners commit to proof of work, now represents one of the largest distributed computing efforts in the world.

In the gold vs bitcoin debate

Bitcoin is frequently called digital gold because both assets derive value from scarcity and neutrality rather than from a counterparty's promise. Gold's above-ground supply grows about 1 to 2 percent per year through mining, while bitcoin's issuance declines on a fixed schedule and stops entirely near the year 2140. Gold offers millennia of history and zero technological risk. Bitcoin offers verifiable supply, borderless settlement, and custody that can be as simple as memorizing 12 words. The debate between them is, at its core, a debate about which properties of money matter most.
