PlanB's Stock to Flow (S2F) model for Bitcoin, which assumes scarcity drives its price, failed to accurately predict market tops in 2021. However, an early 2022 analysis called for Bitcoin's price to move as low as 16.7k, which came true in November 2022. The S2F ratio helps pinpoint the true value of Bitcoin and future price movements.

Historically, the S2F ratio increased with each halving, with bull runs following halving events and succeeded by bear markets. Back in 2013, Bitcoin's price stayed below the S2F targets, hinting at an investment opportunity. The model indicates potential value and price levels for Bitcoin in 2024/25, offering insight for future investment.
