The Bitcoin Halving Explained
📖 5 min read
Quick Answer
Roughly every four years, the amount of new bitcoin created per block is cut in half. This pre-programmed "halving" is how Bitcoin enforces scarcity — and it is one of the most-watched events in all of finance.
💡 Think of it as…
Kohoutek, který do světa kape nové mince – a každé čtyři roky někdo otočí kohoutkem napůl. Tok se stále zmenšuje podle pevného plánu, až se nakonec zcela zastaví na 21 milionech coinů.
The schedule
Every 210,000 blocks (about four years) the block subsidy halves: 50 → 25 → 12.5 → 6.25 → 3.125 BTC, and so on. This continues until around 2140, when issuance ends and the 21-million cap is reached.
Why it exists
The halving makes Bitcoin disinflationary by design: new supply grows ever more slowly, the opposite of fiat currencies that can be printed without limit. It is the core of the "digital gold" and inflation-hedge argument.
The price debate
Historically, halvings have preceded major bull markets as new supply tightened against steady or rising demand. But past performance is not a guarantee, and many factors drive price — treat halving narratives with healthy skepticism.
🔑 Key takeaway
The halving cuts new bitcoin issuance in half every ~4 years, enforcing a fixed 21-million supply. It is scarcity written into the code.
Why this matters for you
For savers in high-inflation Asian economies, the halving is the heart of Bitcoin’s pitch: a money supply no government can inflate away. It is why "protect your savings from inflation" resonates from Turkey to Pakistan.
Často kladené otázky
When is the next Bitcoin halving?▼
The previous halving was in 2024; the next is expected around 2028. The exact date depends on how fast blocks are mined.
Does the halving guarantee the price will rise?▼
No. Halvings reduce new supply, which can support price if demand holds, but markets are complex and nothing is guaranteed. Never invest based on a single narrative.
What happens after all bitcoin is mined?▼
Kolem roku 2140 budou těžaři místo nových coinů vydělávat pouze transakční poplatky. Drtivá většina všech bitcoinů je již dnes v oběhu.
