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…
A faucet that drips new coins into the world — and every four years, someone turns the tap halfway down. The flow keeps shrinking on a fixed schedule until, eventually, it stops entirely at 21 million coins.
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.
Häufig gestellte Fragen
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?▼
Around 2140, miners will earn only transaction fees instead of new coins. The vast majority of all bitcoin is already in circulation today.
