This article delves into four major Bitcoin valuation models: the Production Cost Model, the Stock-to-Flow Model, Metcalfe’s Law, and the AHR999 Hoarding Indicator. By comparing the characteristics and applications of these methods, the article provides readers with a comprehensive perspective on Bitcoin’s value. The Production Cost Model views mining costs as Bitcoin’s price floor, the Stock-to-Flow Model measures scarcity through the stock-to-flow ratio, Metcalfe's Law highlights the exponential impact of user growth on network value, while the AHR999 indicator assists investment decisions by combining short-term dollar-cost-averaging returns with price deviations.
