Cardano (ADA) logarithmic regression bands (AUD)
Long-run logarithmic regression of Cardano's AUD price against time since the ADA mainnet launch (September 2017). Central regression line is fair value; ±1σ and ±2σ bands define overheated and undervalued zones. ADA has ~8 years of price history covering two completed cycles. AUD-native, Updated automatically every day.
Chart
Each gold dot is a Cardano (ADA) AUD monthly close. The central gold line is the long-run logarithmic regression of price against time. The dashed lines above and below are ±1σ and ±2σ bands. The white circle marks the most recent month. Hover any point on the chart to see the exact price, fair value, and sigma deviation for that month. Cardano mainnet launched in September 2017 is the regression origin so the log-log fit is meaningful for this asset (using BTC's 2009 genesis would compress Cardano (ADA)'s entire history into a vertical wall).
ADA historical sigma extremes
| Month | Sigma | Price | Context |
|---|---|---|---|
| December 2017 | +2.41σ | A$0.923 | ICO-era peak, three months after launch |
| August 2021 | +2.21σ | A$3.80 | 2021 peak (all-time-high month-end) |
| September 2021 | +1.93σ | A$2.94 | Smart-contract launch, 2021 top |
| March 2020 | -1.95σ | A$0.050 | COVID crash |
| December 2019 | -1.94σ | A$0.047 | Late-2019 bear-market base |
| November 2019 | -1.68σ | A$0.060 | Late-2019 bear-market base |
What is logarithmic regression?
Log-log linear regression: take log of price on one axis, log of days-since-launch on the other, fit a straight line. Because crypto assets have appreciated exponentially over their lifetimes, the log-log transformation produces near-linear relationships. The fitted line represents long-run fair value; residual standard deviation defines band widths.
Cardano cycle context
- Sep 2017 to Jan 2018: launch through the ICO-era mania peak. ADA went from ~A$0.03 at launch to ~A$1.50 in 4 months.
- 2018-2020: bear market down to A$0.04-0.05.
- 2020-Sep 2021: Shelley mainnet, smart contracts, peak around A$4.
- 2022-2023: second bear cycle, bottomed around A$0.30.
- 2024-2025: secondary peak around A$1.40 in the post-election rally. Underperformed BTC and the SOL/AVAX cohort.
Methodology
- Data source. Monthly ADA/AUD closes from October 2017: CoinMarketCap for the first month, then Yahoo Finance ADA-USD monthly candles, converted at the month-end AUD/USD rate.
- Regression origin. Cardano mainnet launch, September 2017.
- Fit. OLS linear regression on (log10(days), log10(price)).
- Projection. 18 months past latest data point.
- Resilience. Refreshed automatically every day. Each update is checked against a known CoinMarketCap month-end close; if a source fails or the check does not pass, the stored data stays in place and the chart keeps rendering.
Limitations
- Two-cycle sample. ADA has only completed two full cycles. Regression more stable as cycles accumulate.
- Pre-Shelley sample. Cardano's early 2018-2020 period had limited functional use (smart contracts launched in September 2021). The early sample reflects pure speculation; this affects the regression slope.
- Sigma assumes normal residuals. ADA's residual distribution has fatter tails than normal.
- Single-asset reasoning. Use alongside Bitcoin Dominance and Altcoin Season Index for rotation context.

Frequently asked questions
Monthly ADA/AUD price plotted against days since the September 2017 Cardano mainnet launch on log-log axes. OLS regression fitted; central line is long-run fair value. ±1σ and ±2σ bands define overheated and undervalued zones based on the distribution of historical residuals.
Log regression requires positive day counts. Using BTC's 2009 genesis compresses ADA's 2017-onwards history into a thin vertical band. Using ADA's own mainnet launch (September 2017) as origin gives the regression meaningful spread.
Cardano has two cycles in the sample. The ICO-era peak reached +2.41σ in December 2017, and January 2018 closed at A$0.641 (+1.84σ). The bear market bottomed at -1.95σ in the March 2020 COVID crash. The 2021 top reached +2.21σ in August 2021 (month-end A$3.80). The 2022 lows sat near the line (-0.34σ in December 2022), and the December 2024 rally reached +0.82σ.
Subjective interpretation: Cardano's slower, research-driven development pace has been a marketing weakness against faster-moving layer 1s such as Solana. The log regression takes no view; it reflects realised price. ADA's high in this cycle reached only +0.82σ (December 2024), against +2.21σ in August 2021, and it sits at -0.66σ as of October 2026.
Standard OLS linear regression on (log10(days since ADA launch), log10(price in AUD)). Slope and intercept define the central line; the residual standard deviation defines the band widths. Recomputed whenever the data refreshes.
No. Use as one input alongside BTC cycle indicators (Risk Metric, Pi Cycle, Dominance, Altseason Index) and your own fundamental view of Cardano's competitive position. Any sale that triggers a CGT event in Australia should be planned with the Crypto CGT Calculator for after-tax proceeds.
