Bitcoin Thermocap: Understanding Market Valuation Metrics

Technical AnalysisPublished: August 13, 2025Reading time: 8 min

Explore Bitcoin Thermocap, an advanced on-chain metric that provides insights into Bitcoin's fair value by analyzing the cumulative security spend of the network.

What is Bitcoin Thermocap?

Bitcoin Thermocap is an on-chain valuation metric that represents the cumulative security spend of the Bitcoin network. It calculates the total amount of money that has been spent on mining Bitcoin throughout its entire history, providing a unique perspective on the network's intrinsic value.

How Thermocap is Calculated

The Thermocap metric is calculated using the following formula:

Thermocap = Σ (Block Reward × Bitcoin Price at Block Time)

This calculation sums up the USD value of all block rewards (including transaction fees) at the time each block was mined, representing the total security expenditure of the network.

Thermocap vs Market Cap Analysis

Key Differences

Market Cap

  • • Current price × Total supply
  • • Reflects current market sentiment
  • • Highly volatile and speculative
  • • Forward-looking metric

Thermocap

  • • Cumulative security expenditure
  • • Based on historical mining costs
  • • More stable, fundamental metric
  • • Backward-looking valuation

Thermocap Multiple

The Thermocap Multiple is calculated as:

Thermocap Multiple = Market Cap ÷ Thermocap

This ratio helps identify whether Bitcoin is overvalued or undervalued relative to its cumulative security spend. Historical analysis shows:

  • • Multiple < 8: Historically good buying opportunities
  • • Multiple 8-16: Fair value range
  • • Multiple > 16: Potentially overvalued territory

Practical Applications

Investment Strategy

Thermocap can be used for:

  • • Long-term valuation: Identifying fair value based on network security
  • • Market timing: Using Thermocap Multiple for entry/exit decisions
  • • Risk assessment: Understanding when markets are extremely stretched
  • • Portfolio allocation: Adjusting Bitcoin exposure based on valuation metrics

Current Market Context

As of December 2024, Bitcoin's Thermocap provides valuable context for current market conditions. The metric has shown strong correlation with long-term price floors and has been particularly useful during bear markets for identifying accumulation zones.

Important Considerations

  • • Thermocap is a lagging indicator based on historical data
  • • Should be used alongside other metrics for comprehensive analysis
  • • Market conditions and adoption can affect the relevance of historical ratios
  • • Not suitable for short-term trading decisions

Conclusion

Bitcoin Thermocap offers a unique perspective on Bitcoin's valuation by focusing on the cumulative security expenditure of the network. While it shouldn't be used in isolation, it provides valuable insights into Bitcoin's fundamental value and can help investors make more informed long-term decisions.

Understanding metrics like Thermocap is crucial for developing a sophisticated approach to Bitcoin investment and gaining deeper insights into the network's economic dynamics.
