Bitcoin Golden Ratio Multiplier (AUD)
Philip Swift's Golden Ratio Multiplier plots Bitcoin's 350-day moving average multiplied by a sequence of Fibonacci numbers (1.6, 2, 3, 5, 8, 13, 21). Each band marks a zone of price relative to the long-run trend: the 1.6× band (the golden ratio φ) marks above-trend territory and the upper bands mark increasingly stretched conditions. In the AUD data each cycle peak has reached a lower band than the one before: about 5.5× in December 2017, 3.4× in February 2021, 2.1× in March 2024 and 1.58× in January 2025. BTC currently trades at 1.05× its 350-day average. AUD-native, computed client-side from daily BTC/AUD closes.

What band is Bitcoin in right now?
| Band | Price / 350DMA | Historical interpretation |
|---|---|---|
| 21× zone | ≥ 21× | Top band of the model. Not reached anywhere in the AUD data since December 2013. |
| 13-21× zone | 13× - 21× | Cycle peak forming. Distribution territory. |
| 8-13× zone | 8× - 13× | Late-cycle mania. Approaching cycle peak window. |
| 5-8× zone | 5× - 8× | Heated. The December 2017 top peaked here at 5.5×. |
| 3-5× zone | 3× - 5× | Above trend. Mid-to-late cycle bull territory. |
| 2-3× zone | 2× - 3× | Mid cycle. Typical of BTC-led bull phases. |
| 1.6-2× zone | 1.6× - 2× | Near long-run trend. Recovery or early-cycle territory. |
| Below 1.6× (φ) | < 1.6× | Accumulation zone. Below the golden ratio multiple of the 350DMA. |
Has Bitcoin ever hit the 21× band?
| Cycle peak | Multiplier at peak | Did 21× band hit? |
|---|---|---|
| November 2013 | Not measurable (first 350DMA reading 4.3× on 16 December 2013) | Unknown - the data starts in January 2013, too late for a 350-day average at the peak. |
| December 2017 | 5.5× (16 December 2017) | No - peaked in the 5-8× band. |
| Early 2021 | 3.4× (21 February 2021); 2.7× at the 13 April 2021 price high | No - peaked in the 3-5× band. |
| November 2021 (final peak) | 1.6× (8 November 2021) | No - just below the 1.6× band. |
| 2024-2025 cycle | 2.1× (13 March 2024); 1.58× (January 2025) | No - peaked in the 2-3× band. |
The 21× band has not been a cycle-top marker in this dataset. What the chart does show is a steady step-down: each cycle's peak multiplier has been lower than the one before, from 5.5× in 2017 to 3.4× in 2021 to about 2× in 2024-2025. That is consistent with a maturing asset whose rallies stretch less far above the one-year trend. If the pattern continues, a future peak may come in at or below the 2× band (A$224,668 at today's 350DMA) rather than anywhere near 21×.
What is the Golden Ratio Multiplier?
The Golden Ratio Multiplier is a deterministic moving-average-band indicator developed by Philip Swift in 2019. The construction:
- Base line: Bitcoin's 350-day simple moving average.
- Multiplier sequence: Fibonacci-derived multipliers: 1.6 (≈ φ, the golden ratio), 2, 3, 5, 8, 13, 21.
- Band construction: Each multiplier produces a reference line at (350DMA × multiplier). Together they form a band stack from the 350DMA (lowest) to 350DMA × 21 (highest).
- Cycle interpretation: Each band is a reference for how far price is stretched above the one-year trend. In the AUD data the cycle peaks landed in progressively lower bands: 5-8× in 2017, 3-5× in 2021, 2-3× in 2024.
The model has no first-principles theoretical basis. The Fibonacci sequence is a convenient ladder, not a law. Its practical value is as a map of how stretched price is relative to the one-year trend, and the declining peak multiplier across cycles is the observation that has held up in the data.
Methodology
- Data source. Daily BTC/AUD closes from January 2013: Bitstamp BTC/USD converted at the daily AUD/USD rate, with Kraken's native BTC/AUD market for the last two years. Refreshed automatically every day. The first 350-day average falls on 16 December 2013.
- 350DMA. Trailing 350-day simple moving average computed client-side on every page load.
- Bands. Each band line is the 350DMA value multiplied by the band's Fibonacci multiplier for every day. Bands widen over time as the 350DMA rises.
- Classification. Current band determined by Price ÷ 350DMA - the result placed into the closest Fibonacci-multiplier bracket.
- Static-first. If a price source is unreachable, the previous data file is kept and the indicator renders the last good data.

Frequently asked questions
The Golden Ratio Multiplier is a long-term Bitcoin cycle indicator developed by Philip Swift (founder of LookIntoBitcoin) in 2019. It plots Bitcoin's 350-day moving average multiplied by a sequence of Fibonacci-derived numbers: 1.6 (the golden ratio φ ≈ 1.618), 2, 3, 5, 8, 13, and 21. Each multiplier creates a reference band. The feature traders watch is that each cycle peak has reached a lower band than the previous one. In the AUD data the December 2017 top reached 5.5× its 350-day average, the early-2021 high 3.4×, the March 2024 high 2.1× and the 2025 high 1.58×.
As of 8 October 2026, Bitcoin trades at 1.05× its 350-day moving average of A$112,334, which puts it below the 1.6x band. The classification card in the stats grid shows the live reading. The full band hierarchy: below 1.6× = accumulation zone (below the 350DMA × golden ratio); 1.6× to 2× = near the long-run trend; 2× to 3× = mid-cycle; 3× to 5× = above trend; 5× to 8× = heated; 8× to 13× = late-cycle mania; 13× to 21× = cycle peak forming; ≥21× = cycle top zone.
Not in this AUD dataset. The daily data starts in January 2013, so the first 350-day average is on 16 December 2013, after the November 2013 peak; the first reading was 4.3×. Since then the highest reading was 5.5× at the December 2017 top. The 21× band sits far above anything seen in the data; today it is at A$2,359,012. The useful pattern is the declining peak multiplier from one cycle to the next, not the 21× line itself.
Philip Swift derived the multiplier sequence (1.6, 2, 3, 5, 8, 13, 21) from Fibonacci numbers and the golden ratio (φ ≈ 1.618). The Fibonacci numbers themselves don't have a first-principles reason to apply to Bitcoin price action. The bands are a convenient ladder for reading how stretched price is above its one-year trend, and the step-down in peak multiplier across cycles is the part of the model that has held up.
The 350-day window is close to one year of daily closes. It's a smoother long-run trend reference than the 200DMA used in the Mayer Multiple, but more responsive than the 730-day used in the 2YMA Multiplier. Philip Swift chose 350 because it complements his Pi Cycle Top (which uses 111DMA and 350DMA × 2) - the 350DMA is the slower component in both models.
