Bitcoin (BTC)

“Bitcoin is the original cryptocurrency—a purely digital cash system launched in 2009 by the pseudonymous creator Satoshi Nakamoto. Instead of relying on banks or payment processors, it uses a global, peer‑to‑peer network where anyone can send value directly to anyone else. Every transaction is broadcast to thousands of independent computers (nodes), giving Bitcoin its famous resistance to censorship and single‑point failures.

At the heart of Bitcoin lies its public ledger, the blockchain. Specialized participants, called miners, bundle pending transactions into “blocks” and compete to solve a cryptographic puzzle; the winner adds the new block to the chain and earns newly minted bitcoin, plus transaction fees. This proof‑of‑work process issues coins on a predictable schedule that halves roughly every four years, enforcing a hard cap of 21 million BTC and underpinning Bitcoin’s scarcity narrative.

Today, Bitcoin functions as both a borderless payment rail and a digital store of value.

Exchanges quote thousands of crypto‑assets against BTC, and the coin’s eight‑decimal divisibility (the smallest unit is one satoshi, or 0.00000001 BTC) makes micro‑payments feasible even as headline prices rise. From remittances to portfolio diversification, Bitcoin continues to inspire innovation across finance and beyond.
