BTC Halving Cycle Bottom Predictor
Historical halving data and an interactive projector for Bitcoin's 4-year cycle. Set your peak price assumption, days-to-peak, drawdown, and bear duration to model the projected Cycle 4 bottom price and date.
Historical Halving Cycle Data
All four Bitcoin halvings, their cycle peaks, and subsequent bear market bottoms.
| Cycle | Halving date | Price at halving | Cycle peak | Peak date | Days to peak | Peak multiple | Bear bottom | Bottom date | Days peak→bottom | Drawdown |
|---|---|---|---|---|---|---|---|---|---|---|
| 1st (2012) | 28 Nov 2012 | $12 | $1,242 | 30 Nov 2013 | 367 | 104x | $178 | 14 Jan 2015 | 427 | 85.7% |
| 2nd (2016) | 9 Jul 2016 | $650 | $19,783 | 17 Dec 2017 | 526 | 30x | $3,122 | 15 Dec 2018 | 363 | 84.2% |
| 3rd (2020) | 11 May 2020 | $8,600 | $68,789 | 10 Nov 2021 | 548 | 8x | $15,476 | 21 Nov 2022 | 376 | 77.5% |
| 4th (2024) - current | 19 Apr 2024 | $63,800 | TBD | TBD | TBD | TBD | TBD | TBD | TBD | TBD |

Key Cycle Patterns
Cycle 5 Peak Projector (Halving 5 — est. Apr 2028)
Project the Cycle 5 bull market peak. Set the expected Bitcoin price at the 5th halving (a function of where Cycle 4 ends) and a peak multiplier based on the diminishing-returns trend.
How the Cycle Bottom Projector Works
| Parameter | What it controls | Historical range |
|---|---|---|
| Expected peak price | The price level you believe Bitcoin will reach at the cycle top. This is the most influential input and the hardest to predict accurately. | Cycle 1: $1,242 | C2: $19,783 | C3: $68,789 |
| Days from halving to peak | How many days after the halving the cycle peak occurs. Earlier = shorter bull run; later = longer accumulation phase. | C1: 367d | C2: 526d | C3: 548d | Avg (C2+C3): 537d |
| Bear market drawdown | The percentage fall from cycle peak to bear market bottom. A declining trend is observed across cycles as Bitcoin matures. | C1: 85.7% | C2: 84.2% | C3: 77.5% | Trend: declining ~3-4% per cycle |
| Bear market duration | How many days from the peak until the bottom is reached. This determines the timeline of the bear phase. | C1: 427d | C2: 363d | C3: 376d | Avg (C2+C3): 370d |
The tool then projects: Peak date = halving date + days-to-peak. Bottom price = peak price × (1 − drawdown/100). Bottom date = peak date + bear duration. A sensitivity panel shows bottom prices at -65%, your base drawdown, and -85% for scenario comparison.
Analysis Tips
Diminishing returns per cycle
Peak multiples over the halving price: 104x (C1), 30x (C2), 8x (C3). Cycle 4 models typically project 3–5x from the ~$63,800 halving price, implying a peak in the $190K–$320K range.
Watch the progress bar
The bull run progress bar shows where you are in the cycle relative to your assumed peak. If you're past 80% of the projected cycle length, historical patterns suggest the peak window is open.
Drawdown trend matters
Each cycle has seen a smaller percentage drawdown. Institutional accumulation and ETF inflows in Cycle 4 are cited by many analysts as reasons the bottom may be shallower than prior cycles (-60% to -70% vs. historical -77% to -85%).
The sensitivity panel
Use the three-column bottom range (−65% / base / −85%) to frame a bull/base/bear scenario. The base case is your slider setting; −85% is the deeper historical precedent.
Cycle 1 is an outlier
Cycle 1 data (367 days to peak, 104x multiple) reflects a tiny, illiquid market. Analysts typically use only Cycles 2 and 3 for pattern extrapolation to Cycle 4, as the market has since scaled significantly.
Macro matters too
The halving cycle is the on-chain catalyst, but macro conditions (interest rates, liquidity cycles, dollar strength) significantly affect timing and magnitude. The 2022 bear was deepened by the Fed rate hike cycle.
Frequently Asked Questions
What is the Bitcoin halving and why does it matter?
Every 210,000 blocks (approximately every 4 years) the reward paid to Bitcoin miners is cut in half. This reduces the rate at which new BTC enters supply. Historically, this supply shock combined with steady or growing demand has driven significant price appreciation. Four halvings have now occurred: November 2012, July 2016, May 2020, and April 2024.
How accurate is the 4-year cycle theory?
The theory is a pattern observed over three completed cycles, not a law. Cycles 2 and 3 show strong consistency in days-to-peak (526 and 548 days), drawdown range (84.2% and 77.5%), and post-peak bear duration (363 and 376 days). However, as Bitcoin matures and attracts institutional capital, each cycle is expected to reduce in volatility. The pattern should be treated as probabilistic context, not prediction.
What does the drawdown percentage mean?
The drawdown is the percentage fall from the cycle peak price to the bear market bottom. In Cycle 2, Bitcoin fell 84.2% from $19,783 to $3,122. In Cycle 3 it fell 77.5% from $68,789 to $15,476. The trend toward smaller drawdowns per cycle is a common thesis: institutional buyers and long-term holders accumulate during bear markets, compressing the downside with each cycle.
How do I use the projector?
Set your expected cycle peak price using the slider or number input. Adjust days-to-peak based on your view of how long the bull market will run (historical average is 537 days from halving). Set your expected bear market drawdown and duration. The tool then projects the peak date, bottom date, and bottom price. The sensitivity analysis shows alternative scenarios at -65% and -85% drawdown.
What is the current Bitcoin cycle phase?
The 4th halving occurred on 19 April 2024. The tool calculates the current day count from that date and maps it against your projected peak timeline. The phase indicator will read Early Bull (0-40% of cycle), Mid Bull (40-80%), Late Bull (80-100%), or Post-Peak Bear Market (past projected peak day).
When is the next Bitcoin halving?
The 5th halving is expected around April 2028, when Bitcoin reaches block 1,050,000. The exact date depends on the average time per block, which fluctuates with mining difficulty adjustments. The estimate of April 17, 2028 shown in the tool is based on the average 10-minute block time from the 4th halving.
Is this tool financial advice?
No. This tool presents historical patterns and allows you to model scenarios based on your own assumptions. Bitcoin is a highly volatile asset. Past halving cycles do not guarantee future performance. The bear market bottom projections depend entirely on whether the assumed peak price and timing are correct. Always conduct your own research and consult a financial advisor before investing.
