The Stock-to-Flow (S2F) model is one of the most widely referenced analytical approaches for predicting Bitcoin’s price. This model evaluates asset value based on the ratio of existing supply (stock) to new supply (flow). For Bitcoin, halvings—which occur roughly every four years—cut new issuance in half. As a result, the S2F model places significant emphasis on this supply constraint in its price forecasts.
In recent market cycles, the S2F model has forecasted Bitcoin’s peak price at $222,000. This projection draws on historical post-halving price surges and the mechanics of supply reductions. However, Andrei Dragosch, Head of Research Europe at Bitwise, warns of the risks posed by over-reliance on this model.
Dragosch highlights that the S2F model’s greatest flaw is its bias toward supply-side factors, overlooking key developments on the demand side. In particular, institutional demand—such as through Bitcoin ETFs and corporate treasury allocations—has become increasingly prominent in recent years.
These institutional inflows now surpass the annual supply reduction from past halving events by more than sevenfold. Simply put, rising demand now exerts a much greater influence on price than supply cuts alone. Because the S2F model fails to account for this shift in demand dynamics, Dragosch cautions that its price forecasts face inherent limitations.
Despite the recognized shortcomings of the S2F model, institutional participation has delivered strong price support for Bitcoin. Involvement through ETFs and other investment vehicles has helped Bitcoin sustain price levels above $100,000.
Institutional demand differs fundamentally from retail investors. Institutions tend to take a long-term, strategic approach and are less reactive to short-term market swings. Additionally, more corporate treasury departments are holding Bitcoin as an asset, which is contributing to both market stability and price support.
As the market matures and institutional involvement deepens, investors and analysts are actively debating whether Bitcoin has already peaked or if further upside potential remains.
Whether the S2F model’s $222,000 target materializes depends on many factors beyond supply constraints—such as the persistence of institutional demand, regulatory changes, and macroeconomic trends. Dragosch’s observations highlight the importance for investors to avoid relying on a single model and instead analyze both supply and demand comprehensively.
Dragosch advises investors to exercise caution when using the S2F model to assess Bitcoin. The model is just one analytical tool, and investors should consider institutional demand, regulatory developments, technological advances, and broader adoption trends to gain a full market perspective.
Unlike previous cycles, the influence of institutional investors has grown dramatically. Understanding this structural shift—and assessing not only supply reductions but also the sustainability of demand growth—has become essential for Bitcoin investment. Investors are encouraged to combine multiple analytical methods and maintain rigorous risk management in their decision-making.
The Bitcoin S2F model predicts Bitcoin’s price by using the ratio of total current supply to annual new supply. A higher ratio signals greater scarcity, implying potential future appreciation. The S2F model offers a framework for evaluating an asset’s relative value.
The S2F model focuses exclusively on the supply side, ignoring demand shifts and market sentiment. Overdependence on a single model can disconnect forecasts from market realities and reduce predictive accuracy.
The S2F model’s chief flaws are its limited sample size and the high uncertainty of its projections. Halving events heavily influence the model, and its underlying assumptions may not always hold true. Its projected price range—spanning from $83,000 to $1,480,000—is so wide that it limits practical utility.
Technical methods include the 200-week moving average, 2-year moving average, and Pi Cycle indicator. Fundamental metrics like Coin Days Destroyed, Puell Multiple, and Golden Ratio Multiplier are also used, combining on-chain data and market cycles to estimate Bitcoin price bottoms and peaks.
The S2F model delivered reasonably accurate forecasts up to 2020, but its predictive accuracy has since declined. Its long-term reliability is now in question, as it cannot fully capture the market’s growing complexity.
Some institutional investors reference the S2F model, but it is not their sole basis for decisions. They use comprehensive analyses, including fundamentals, macroeconomic conditions, and market sentiment, to guide their investment strategies.
