Thermocap measures the total revenue paid to Bitcoin miners since the genesis block, calculated as the cumulative sum of all block rewards and transaction fees in USD terms. It represents the minimum cost of producing all existing Bitcoin.

Bitcoin's Thermocap tracks every dollar that has been paid to miners through block subsidies and transaction fees since January 2009. Because miners are the primary sellers in the Bitcoin economy — they must sell coins to cover electricity and hardware costs — Thermocap approximates the cumulative cost of securing the network and producing the entire coin supply.
The Thermocap Multiple divides Bitcoin's market cap by its Thermocap to gauge how much speculative premium exists above the production cost floor. Historically, a Thermocap Multiple above 32 has coincided with cycle tops, while readings below 8 have marked strong accumulation zones. The logic is straightforward: the further price deviates above the total cost of mining, the more speculative the market becomes.
Thermocap is particularly useful as a long-term valuation anchor because it only grows — miners always earn revenue, so the cumulative total always increases. This monotonic growth makes it a stable reference point compared to more volatile metrics. When combined with realized cap and market cap, Thermocap completes a three-layer valuation framework: production cost, holder cost basis, and speculative valuation.
The Thermocap Multiple measures how far Bitcoin's market valuation has exceeded the total cost of mining all coins. A high multiple means the market is paying a large premium over production cost, which has historically preceded corrections. A low multiple suggests price is close to the cost floor.
Thermocap is essentially the total security budget that has been spent to protect the network. It reflects the real economic resources — electricity, hardware, labor — that miners have expended. A growing Thermocap means increasing investment in network security over time.
Halvings slow the growth rate of Thermocap because block subsidies are cut in half. However, Thermocap continues to grow as miners still earn reduced subsidies plus transaction fees. Over time, fees are expected to become a larger share of miner revenue and Thermocap growth.
