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.

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 672 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.

Cycle history
The four Bitcoin halving cycles, side by side
Bitcoin has now completed four halving cycles. Each one rhymes with the others without repeating them exactly, and looking at all four lets you separate the structural pattern from the path-dependent noise.
Cycle 1 — November 2012 halving
The first halving cut the block reward from 50 BTC to 25 BTC. Bitcoin was $12 on halving day. It ran to roughly $1,150 in November 2013 — approximately 96× from halving day in 12 months. This cycle had the highest peak ROI in history because the market was so small and so structurally constrained: the same dollar of new demand moved the price much further than it would in any subsequent cycle.
Cycle 2 — July 2016 halving
Block reward fell from 25 BTC to 12.5 BTC. Bitcoin was $660 on halving day. The cycle peaked at roughly $19,800 in December 2017 — approximately 30× from halving day over 17 months. The first ICO bubble layered on top of the halving narrative drove the late-cycle parabolic move. Time-to-peak: ~525 days from halving.
Cycle 3 — May 2020 halving
Block reward fell from 12.5 BTC to 6.25 BTC. Bitcoin was $8,700 on halving day. The cycle peaked at roughly $69,000 in November 2021 — approximately 7.9× from halving day over 18 months. This cycle had an unusual double-peak structure (April 2021 and November 2021) with a 50% drawdown between them, complicated by China mining bans and macroeconomic regime change. Time-to-peak: ~545 days from halving (using the November high).
Cycle 4 — April 2024 halving (current)
Block reward fell from 6.25 BTC to 3.125 BTC. Bitcoin was $64,300 on halving day. Following the diminishing-returns pattern (96× → 30× → 7.9×), a 2–4× ROI from halving day would be consistent with the trend — implying a cycle peak somewhere in the $130,000–$260,000 range, likely printing between October 2025 and June 2026 if historical time-to-peak holds. Spot Bitcoin ETFs, approved three months before this halving, fundamentally changed the demand structure of the cycle — the first halving where TradFi inflows are a meaningful component of price action.
What is different this time, and what is not
The single biggest structural change between this cycle and prior ones is the ETF demand channel. Spot Bitcoin ETFs absorb roughly 2,000–4,000 BTC per day in net buying during accumulation phases — comparable in magnitude to daily new issuance at the current reward schedule (~450 BTC/day post-halving). This is a permanent demand sink that did not exist in cycles 1–3.
What is unchanged is the supply mechanics. The halving still cuts new issuance in half on schedule; miners still hold a structural sell-pressure footprint; and the four-year cycle structure has now repeated four times. The base case for this cycle is that the diminishing-returns trend continues but with TradFi demand creating a higher cycle low and a smoother cycle path than prior ones. Tactical context: pair this chart with Fear & Greed sentiment and whale-tracker accumulation data for a richer cycle-position read.
