Bitcoin (BTC)

Bitcoin is the asset every other crypto is measured against. It launched in January 2009 as a fixed-supply digital currency with no issuer and no central operator — 21 million coins, and no mechanism to create more. This hub collects MEXC Learn's Bitcoin coverage, from how the supply schedule works to what actually moves the price. New to it? Start with what makes Bitcoin scarce, how a transaction settles, and why BTC gets described as a store of value rather than a payments network. From there the coverage splits three ways. Supply and monetary design. Roughly every four years the reward paid to miners halves, cutting the rate of new issuance. The April 2024 halving dropped it to 3.125 BTC per block. Articles here cover the halving schedule, the 21 million cap, and the UTXO model that tracks who owns what. Network and technology. Bitcoin still runs on proof of work, so miners compete with hardware for the right to add each block. This track covers mining economics, hash rate, the Lightning Network for fast low-cost payments, and inscriptions — the practice of embedding data in individual satoshis. Markets and institutional access. US spot Bitcoin ETFs began trading in January 2024, giving institutions direct price exposure without holding keys. Coverage here tracks ETF structure, halving cycle history, and how BTC trades against the rest of the market. Every guide here explains the mechanism, not just the headline.
