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 represents a historically-meaningful zone: the 1.6× band (the golden ratio φ) marks above-trend territory; the 21× band marks historical cycle tops. Every Bitcoin cycle since 2013 has peaked at or near the 21× band. AUD-native, computed client-side from the daily BTC AUD price seed.
Chart
BTC AUD daily price (gold solid line), 350-day moving average (white solid line), and Fibonacci multiplier bands (coloured dashed lines: 1.6×, 2×, 3×, 5×, 8×, 13×, 21×). The 21× band marks Bitcoin's historical cycle-top zone. Hover any point for the exact price, 350DMA, and current multiplier.
What band is Bitcoin in right now?
| Band | Price / 350DMA | Historical interpretation |
|---|---|---|
| 21× zone | ≥ 21× | Cycle top zone. Every cycle peak since 2013 has visited this band. |
| 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. Bull-market acceleration phase. |
| 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 | ~21× | Yes - peaked right at the 21× band. |
| December 2017 | ~25-30× (briefly) | Yes - actually exceeded 21× during the parabolic blow-off. |
| April 2021 (first peak) | ~17× | No - first 2021 peak fell just short. |
| November 2021 (final peak) | ~21× exact | Yes - November 2021 secondary peak printed right at 21×. |
| 2024-2025 cycle | TBD (in progress) | Not yet. The current cycle has not visited the 21× band. |
The 21× band has been remarkably consistent as a cycle-top marker across three completed cycles with very different absolute price levels. The November 2021 peak printing at 21× exact (despite the 2024-2025 ETF era being unprecedented in Bitcoin's market structure) is the strongest evidence that the model retains predictive power going forward. If the current cycle follows the historical pattern, the 21× band represents the cycle-top target zone - currently sitting at the AUD level shown in the stats grid.
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 has been empirically meaningful as a zone where Bitcoin's price has either found resistance or marked a cycle-position milestone. The 21× band has marked every cycle peak since 2013.
The model has no first-principles theoretical basis - the Fibonacci sequence was chosen by Philip Swift empirically because it produced the cleanest fit across the 2013, 2017, and 2021 cycle peak zones. The model's strength is empirical consistency; its weakness is the same (no first-principles framework would predict that Fibonacci multipliers should determine Bitcoin's cycle zones).
Methodology
- Data source. Daily BTC/AUD close prices from January 2014 onwards. CryptoCompare primary + CoinGecko fallback.
- 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 the upstream source is unreachable, the previous data file is preserved and the indicator continues to render with last-known-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. Bitcoin has historically respected these bands as resistance and support zones. The 21× band specifically has marked historical cycle peaks - every Bitcoin cycle top since 2013 has printed at or near the 21× multiplier of the contemporary 350DMA.
The current band is shown in the classification card in the stats grid above the chart. 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.
Yes, at every cycle peak. The November 2013, December 2017, and November 2021 cycle tops all printed at or above 21× their contemporary 350-day moving average. The 2017 peak briefly exceeded 21× (reaching close to 30× at its absolute peak). The 2021 peak printed right at 21×. The 21× band has been remarkably consistent across cycles despite Bitcoin's market structure maturing dramatically. The 2024-2025 cycle has not (yet) reached 21× - the chart above shows where the 21× target currently sits in AUD terms.
Philip Swift derived the multiplier sequence (1.6, 2, 3, 5, 8, 13, 21) from Fibonacci numbers and the golden ratio (φ ≈ 1.618) empirically - he tested which multiplier sequences cleanly aligned with Bitcoin's historical cycle zones across the 2013, 2017, and 2021 cycle tops. The Fibonacci numbers themselves don't have a first-principles theoretical reason to apply to Bitcoin price action, but the empirical fit across three completed cycles has been strong enough that the model has been widely adopted as a cycle-positioning reference.
The 350-day window is approximately one year of trading days (~350 working days in a 365-day calendar after weekends and holidays). 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 specifically chose 350 because it complements his Pi Cycle Top (which uses 111DMA and 350DMA × 2) - the 350DMA is the slower component in both models.
