Bitcoin halving explained

The Bitcoin halving is a pre-programmed event that cuts the mining block reward in half approximately every four years (every 210,000 blocks).

The most recent halving occurred in April 2024, reducing the reward from 6.25 BTC to 3.125 BTC per block. The next halving is expected around early 2028.

Halvings are significant because they reduce the rate at which new Bitcoin enters circulation, making Bitcoin progressively scarcer — a core property that underpins its value proposition as a deflationary monetary asset.

How the halving works

Bitcoin's creator, Satoshi Nakamoto, designed the halving into Bitcoin's code as a fixed monetary policy. Unlike central banks that can print unlimited currency, Bitcoin's issuance follows a precise, unchangeable schedule:

1. 2009 (launch): 50 BTC per block — approximately 7,200 BTC created per day

2. 2012 (1st halving): 25 BTC per block — daily creation halved

3. 2016 (2nd halving): 12.5 BTC per block

4. 2020 (3rd halving): 6.25 BTC per block

5. 2024 (4th halving): 3.125 BTC per block — approximately 450 BTC created per day

6. 2028 (5th halving): 1.5625 BTC per block expected

Each halving reduces Bitcoin's annual inflation rate. After the 2024 halving, Bitcoin's inflation rate dropped below 1% — lower than gold's estimated annual supply increase of approximately 1.5%. By the 2028 halving, Bitcoin's inflation rate will drop below 0.5%.

The halvings continue until approximately the year 2140, when the final satoshi (the smallest Bitcoin unit, 0.00000001 BTC) is mined and the total supply reaches its hard cap of 21 million Bitcoin.

Why the halving matters

Supply reduction

The halving is a supply shock. Before the 2024 halving, miners produced approximately 900 BTC per day. After the halving, they produce approximately 450 BTC per day. If demand remains constant (or increases), fewer new Bitcoin available for sale means upward price pressure.

This is the economic logic behind Bitcoin's deflationary design: unlike fiat currencies, where central banks can increase supply at will (causing inflation), Bitcoin's supply is mathematically capped, and the creation rate decreases over time.

Stock-to-Flow

The stock-to-flow (S2F) ratio measures scarcity by comparing existing supply (stock) to new production (flow). After the 2024 halving, Bitcoin's S2F ratio approximately doubled — meaning it takes twice as long for new mining to produce an amount equal to the existing supply. By S2F metrics, Bitcoin is now scarcer than gold.

Miner economics

Each halving cuts miners' revenue (in BTC terms) in half. This forces less efficient miners to shut down, temporarily reduces hash rate, and concentrates mining among the most cost-efficient operations. Historically, the network has quickly recovered as Bitcoin's price appreciation more than compensates for the reduced block reward.

Historical halving price impact

Every previous halving has been followed by a significant bull market, though with increasing time lags and diminishing percentage returns.

1st halving (November 2012): Bitcoin was approximately $12 at the halving. It reached approximately $1,100 within 12 months — a roughly 90x increase.

2nd halving (July 2016): Bitcoin was approximately $650 at the halving. It reached approximately $19,700 by December 2017 — a roughly 30x increase over 17 months.

3rd halving (May 2020): Bitcoin was approximately $8,800 at the halving. It reached approximately $69,000 by November 2021 — a roughly 8x increase over 18 months.

4th halving (April 2024): Bitcoin was approximately $64,000 at the halving. The post-halving cycle is still playing out as of early 2026.

The pattern shows diminishing percentage returns with each cycle (90x → 30x → 8x), which is expected as Bitcoin's market cap grows and the supply shock becomes proportionally smaller relative to the total supply. However, even diminishing returns on an increasingly large base represent substantial absolute price movement.

Important caveat: Past performance does not guarantee future results. Many factors beyond the halving influence Bitcoin's price, including macroeconomic conditions, regulatory changes, institutional adoption, and broader market sentiment.

The next halving: ~2028

The 5th halving is expected around March-April 2028 (when block height reaches 1,050,000). The block reward will decrease from 3.125 BTC to 1.5625 BTC. At that point, Bitcoin's annual inflation rate will drop below 0.5%, daily new supply will fall to approximately 225 BTC, and the total supply will be approximately 20.67 million out of the 21 million maximum.

What the halving means for Bitcoin investors

For investors accumulating Bitcoin through platforms like Bitwala, the halving reinforces the long-term thesis. Each halving makes Bitcoin demonstrably scarcer. The post-halving period has historically been the strongest phase of Bitcoin's price cycle, and DCA (dollar-cost averaging) through the full halving cycle captures both pre-halving accumulation at lower prices and post-halving appreciation.

The 1-year German tax-free holding rule aligns well with halving cycles — investors who accumulate before a halving and hold for over a year may benefit from both tax-free treatment and the historical post-halving price appreciation.

FAQ

What is the Bitcoin halving?

The Bitcoin halving is a scheduled event that cuts the mining block reward in half every 210,000 blocks (approximately every 4 years). It reduces the rate at which new Bitcoin is created, making the asset progressively scarcer. The most recent halving occurred in April 2024.

When is the next Bitcoin halving?

The 5th Bitcoin halving is expected around March-April 2028. The exact date depends on block production speed but can be estimated within a few weeks based on current block intervals.

Does the halving always increase bitcoin's price?

Every previous halving has been followed by a significant price increase within 12-18 months. However, past performance does not guarantee future results. The halving reduces supply, but price depends on both supply and demand — macroeconomic conditions and market sentiment also play major roles.

How many Bitcoin halvings are left?

As of 2026, there have been 4 halvings. Approximately 29 more halvings will occur before the final Bitcoin is mined around 2140. Each successive halving has diminishing impact on supply since the reduction gets smaller in absolute terms.

Should I buy Bitcoin before or after the halving?

Historically, buying before the halving (during the accumulation phase) has been more profitable than buying after (when the post-halving rally is already underway). However, DCA (dollar-cost averaging) through the entire cycle — before, during, and after the halving — removes the timing risk entirely. Platforms like Bitwala support automated recurring purchases that make this straightforward.
