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.
Bitcoin FAQ
Bitcoin is a digital currency that runs on a public network with no company, bank, or government behind it. Rules are enforced by software that thousands of independent nodes run voluntarily. Changing those rules requires broad agreement across miners, node operators, and developers — which is why Bitcoin changes slowly and deliberately.
Every 210,000 blocks — roughly four years — the reward miners receive for adding a block is cut in half. The April 2024 halving reduced it from 6.25 to 3.125 BTC. The next is expected around 2028. Halvings matter because they are the mechanism that enforces Bitcoin's declining issuance rate.
The cap comes from the halving schedule. Each halving cuts issuance, and the sum of that shrinking series converges just under 21 million. It was a design choice, written into the software at launch, meant to make the supply predictable in a way that a central bank's is not. Roughly 19.9 million have been mined so far.
No — pseudonymous. Every transaction is permanently public, tied to an address rather than a name. Once an address is linked to an identity, through an exchange withdrawal or a public post, its entire history becomes traceable. Chain analysis firms do exactly this professionally.
Create an account and complete KYC verification, then fund it by card, bank transfer, P2P, or a crypto deposit. Most users buy a stablecoin such as USDT first, then trade it for BTC on the BTC/USDT spot market. From there you can hold it, withdraw it to your own wallet, or move it into other products.
