Episode notes
Price Versus Power-Law Trend
- Bitcoin currently trades slightly below its power-law trend, roughly half a standard deviation under the long-term fit.
- Stephen Perrenod argues this shortfall is normal volatility, not evidence of a new bear market.
Four-Year Cycle Misconception
- The apparent four-year halving cycle is a mistaken inference from few data points and coincidence.
- Bubbles aren't driven materially by halvings today because supply flow is negligible versus demand from ETFs and treasuries.
Log‑Periodic Bubble Timing
- Bubble timings fit a log-periodic spacing parameter, not a fixed four-year cadence.
- Fitting 2011–2021 gives a characteristic log wavelength (~2.07) predicting the next fundamental bubble around mid-2027.
