+# Stock-to-Flow (S2F) Model: A Technical Guide with Mermaid Chart
+
+The Stock-to-Flow (S2F) model is a method used to evaluate the scarcity and value of commodities, including cryptocurrencies like Bitcoin. This guide covers the technical aspects of the S2F model, including a Mermaid chart to visually explain the model's components and implications.
+
+## Understanding Stock-to-Flow
+
+The S2F model is based on two primary components:
+
+- **Stock**: The total supply of the asset currently available.
+- **Flow**: The annual production of the asset.
+
+### Formula
+
+The Stock-to-Flow ratio is calculated using the formula:
+
+```
+S2F = Stock / Flow
+```
+
+This ratio provides a measure of scarcity by comparing the current stock of an asset against the rate at which new supply is produced.
+
+## Visualizing S2F with Mermaid
+
+Below is a Mermaid chart that visually represents the relationship between stock, flow, and the S2F ratio.
+
+```mermaid
+graph TD;
+    A[Stock] -->|Divided by| B(Flow)
+    B --> C{S2F Ratio}
+    C --> D[Scarcity]
+    D --> E[Perceived Value]
+```
+
+This diagram illustrates how the stock and flow contribute to the S2F ratio, which in turn affects the asset's scarcity and its perceived value.
+
+## Application to Cryptocurrencies
+
+Cryptocurrencies, particularly Bitcoin, have a predetermined issuance schedule, making the S2F model particularly relevant. The model highlights how halving events impact Bitcoin's scarcity and, by extension, its value.
+
+### Bitcoin's S2F Analysis
+
+- **Pre-Halving**: Before a halving, the S2F ratio is lower, reflecting a higher flow relative to the stock.
+- **Post-Halving**: After a halving, the flow decreases, increasing the S2F ratio and indicating higher scarcity.
+
+## Criticisms and Limitations
+
+While the S2F model is popular, it faces criticism for oversimplifying supply and demand dynamics and its predictive power.
+
+## How to Use the S2F Model
+
+1. **Calculate S2F Ratio**: Determine the stock and annual production (flow) of the asset.
+2. **Analyze Historical Data**: Look at past changes in the S2F ratio and price correlations.
+3. **Consider Halving Events**: For cryptocurrencies, assess the impact of halving events on scarcity and value.
+4. **Combine with Other Analyses**: Use S2F as part of a broader market analysis strategy.
+
+## Conclusion
+
+The Stock-to-Flow model, complemented by visual aids like Mermaid charts, provides insights into asset scarcity and value. It's a valuable tool when used alongside other analyses in understanding market dynamics.
