Bitcoin Reflexivity and Evidence for Crypto Trend Following
Summary
The article links Bitcoin’s value to adoption and investor confidence, arguing that rising prices can attract participants and strengthen the conditions supporting further gains. The same feedback can work in reverse, producing sharp swings. It suggests that shared attention to technical signals can reinforce these trends. The argument frames momentum as a consequence of market behavior rather than a fixed valuation model.
To examine the idea, the article compares asset autocorrelation using the Hurst exponent and return distributions using kurtosis. It reports that Bitcoin showed higher autocorrelation than the other assets in a two-year comparison, while BTC and ETH had more dispersed daily returns. It then describes a long-only rule that enters when price is sufficiently above its 20-day average and exits when that momentum signal weakens. The reported backtests favor BTC and ETH over crude oil and the S&P 500, and Bitcoin’s strong weeks were followed by better-than-average returns. These examples are exploratory: the article gives no full performance statistics or implementation details, and notes that Hurst alone does not measure trend magnitude.
Key ideas
- Bitcoin’s adoption and investor confidence can reinforce price moves in either direction.
- The Hurst exponent can compare time-series persistence, but it does not measure the size of trends.
- Return distributions add context about the magnitude of daily moves.
- A long-only moving-average distance signal is used to test trend following across assets.
- The reported comparisons favor crypto momentum, but do not establish that the strategy will persist.
