Bitcoin Halving Cycle Comparison (2012 – 2026)
Every Bitcoin halving has marked the start of a major bull cycle. This chart plots BTC's first 600 days post-halving for all four cycles — indexed to 100 on halving day, log-scale — so you can compare them apples-to-apples and read the current cycle against history.
Chart · 4 cycles overlaid
Indexed price action since each halving
All four cycles, scaled so that halving day = 100. The current cycle is the thicker line with a "Today" marker.
Cycle metrics
Every halving, side by side
Historical price levels and time-to-top for the three completed cycles. Cycle 4 is still in progress.
| Cycle | Halving date | Price at halving | Cycle top price | Cycle ROI | Days to top |
|---|---|---|---|---|---|
| Cycle 1 | 2012-11-28 | $12.35 | $1,163 | +9,317% | 367 |
| Cycle 2 | 2016-07-09 | $657 | $19,783 | +2,911% | 526 |
| Cycle 3 | 2020-05-11 | $8,590 | $68,789 | +701% | 548 |
| Cycle 4 CURRENT | 2024-04-20 | $63,800 | in progress | — | — |
ROI = (peak − price-at-halving) / price-at-halving × 100. Peak prices are intraday all-time highs from the corresponding cycle.
Background
How Bitcoin halvings shape the market
Every 210,000 blocks — roughly every four years — Bitcoin's protocol cuts the per-block reward that miners receive in half. This is called the halving, and it's hard-coded into the chain. Cycle 1 (Nov 2012) reduced the reward from 50 BTC to 25; Cycle 2 (Jul 2016) to 12.5; Cycle 3 (May 2020) to 6.25; and Cycle 4 (Apr 2024) to 3.125 BTC per block.
The mechanical effect is a sudden 50% drop in the rate of new BTC issuance. With unchanged demand, this supply shock has historically translated into multi-quarter rallies — though the magnitude has compressed each cycle. Cycle 1 ran ~9,000% from halving to top; Cycle 3 ran ~700%. Cycle 4 is still in progress.
The pattern isn't deterministic. Halvings don't cause bull markets — they coincide with them because the supply shock interacts with adoption, liquidity cycles, and macro conditions. Cycle 3's rally happened under unprecedented monetary expansion; Cycle 4 is unfolding alongside spot ETF demand and a tighter Fed.
What's useful is comparing cycles on a normalised, log-scaled basis — exactly what the chart above does. If the current cycle is tracking ahead of or behind prior cycles by similar days-since-halving, that tells you something about whether the rally has "more in the tank" or has already over-extended.
All four halvings
- Cycle 1 (2012) 2012-11-28 · block 210,000
- Cycle 2 (2016) 2016-07-09 · block 420,000
- Cycle 3 (2020) 2020-05-11 · block 630,000
- Cycle 4 (2024) — current 2024-04-20 · block 840,000
How to read the chart
- →X-axis: days since the corresponding halving (0 to 600).
- →Y-axis: BTC price indexed to 100 on halving day, on a log scale so all four cycles fit.
- →Earlier cycles ran further in percentage terms (Cycle 1 hit the top of the chart), but later cycles still rhyme.
- ●The current cycle is on day 761 post-halving — find the "Today" marker on the highlighted line.
FAQ
Bitcoin halving — frequently asked questions
What is a Bitcoin halving?
Every 210,000 blocks (~4 years), Bitcoin's block reward — the BTC paid to miners for adding a new block to the chain — is automatically cut in half by the protocol. This permanently reduces the rate at which new bitcoin enters circulation, creating a supply shock.
When is the next Bitcoin halving?
The next halving (the 5th) occurs at block 1,050,000 — currently estimated to arrive in 691 days. At that point the block reward drops from 3.125 BTC to 1.5625 BTC. Estimates can shift by weeks depending on hashrate fluctuations.
Does the halving always cause a bull market?
Historically, all three completed halvings have been followed by major bull cycles — but the supply shock is just one input. Cycle 3 also benefited from extreme monetary easing; Cycle 4 is interacting with spot ETF flows and tighter macro. Halvings don't guarantee anything; they tilt the supply/demand balance.
How long after a halving does the price peak?
Cycle 1 peaked 367 days after halving; Cycle 2 took 526 days; Cycle 3 took 548 days. The trend has been longer cycles. If Cycle 4 follows the pattern, a peak would arrive ~18 months post-halving — around late 2025.
Is the halving already "priced in"?
The halving date is public information, so it's priced in efficiently in the short term — there's no surprise about block reward dropping. What isn't priced in is the second-order effect: how reduced new supply meets ongoing demand. That plays out over months, not days.
