From power laws to AI networks, why complex Bitcoin price models memorize market noise

Bitcoin price forecasting has accumulated an unusually colorful collection of methods.

You have basic scarcity models that convert the halving schedule into a price, and run-of-the-mill on-chain models that turn address or transaction activity into value.

The highly contested power-law charts draw an ascending corridor through Bitcoin's history, and machine-learning systems feed market and macroeconomic data into incredibly complex software.

Each of those approaches enters the price-prediction contest against a very shallow, dumbed-down opponent: naive forecasts that use only current market information. A price forecast can use today's price, a return forecast can use zero, and a direction forecast can use a random walk.

Much of the academic literature has struggled to beat it once a model leaves the period in which it was designed.

A May 2026 preprint reviewing Bitcoin prediction research by Carlos Baquero of the University of Porto reached a pretty sobering conclusion: across the peer-reviewed record, no model had demonstrated durable superiority over the appropriate naive benchmark at horizons of one to six months across several market regimes.

The literature contains hundreds of papers, while Baquero selected 23 for close examination based on their methods, influence, or use of genuine out-of-sample evaluation. The review itself is still awaiting peer review, an important distinction when one of its central arguments is that forecasting claims need stronger evaluation.
