Bitcoin by the numbers
The key figures behind Bitcoin in one place: what exists, what it is worth, how the network runs, and the fixed schedule that governs its supply. The live figures below refresh every hour; the historical facts and the halving schedule never change. Every number is sourced.
Last updated 17 Jul 2026 · live metrics from the Bitcoin network
Live metrics (price, market cap, block height, hashrate, difficulty) update hourly from mempool.space; fixed figures are protocol facts.
The halving schedule
Every 210,000 blocks, the reward paid to miners is cut in half. This is the mechanism that caps Bitcoin at 21 million and makes its issuance perfectly predictable. Block heights are fixed by the protocol; only the future calendar dates are estimates.
| Halving | Block height | Date | Reward before | Reward after |
|---|---|---|---|---|
| 1 | 210,000 | 28 Nov 2012 | 50 BTC | 25 BTC |
| 2 | 420,000 | 9 Jul 2016 | 25 BTC | 12.5 BTC |
| 3 | 630,000 | 11 May 2020 | 12.5 BTC | 6.25 BTC |
| 4 | 840,000 | 20 Apr 2024 | 6.25 BTC | 3.125 BTC |
| 5 projected | 1,050,000 | projected ~April 2028 | 3.125 BTC | 1.5625 BTC |
| 6 projected | 1,260,000 | projected ~2032 | 1.5625 BTC | 0.78125 BTC |
The genesis block (2009) began at a 50 BTC subsidy. After the final halving, around the year 2140, no new bitcoin will be created. How Bitcoin works →

Network, energy & adoption
Legal tender: as of 2026, no country mandates Bitcoin as legal tender. El Salvador (adopted 2021) retains only a weakened, voluntary status after a 2025 IMF reform; the Central African Republic repealed its 2022 law. Institutional adoption →

Sources & method
Fixed figures (supply cap, halving block heights, price milestones) are protocol facts and historical record. Live metrics refresh hourly from the Bitcoin network via mempool.space. Slow-moving figures (circulating supply, holdings, energy) are point-in-time and dated on the page. Primary sources include the Cambridge CBECI (energy), SEC filings (corporate holdings), and on-chain data providers. Where estimates are disputed, we note the range rather than a single number.
