Thermocap Multiple
Market cap divided by total cumulative miner revenue (Thermocap). Measures how much speculative premium investors are paying above the security spend invested into the network.
What is it?
The Thermocap Multiple is the direct Market Cap / Thermocap ratio plotted as a single time series. Thermocap represents the cumulative sum of all block rewards and fees paid to miners in USD at issuance time - it is the total network security cost since genesis. The Multiple measures how much the market values each dollar invested in security: the higher the multiple, the further the network valuation drifts from the real cost of production. The fundamental idea is that there exists a long-term relationship between valuation and security spend, and that extremes of the multiple mark cyclical imbalances.
How to read
A single time-series curve of the MC/Thermocap ratio is plotted. Multiple peaks historically coincide with cycle tops (exuberant valuation relative to security cost), troughs with cycle bottoms (compressed valuation close to production cost). The overlaid BTC Price enables correlating market phases with multiple regimes. The long-term trend of the multiple is declining as Thermocap structurally grows faster than Market Cap in the maturation phase.
Key zones
Multiple peaks historically occur at cycle tops, troughs at cycle bottoms - absolute levels have gradually declined across cycles as Thermocap structurally grows. Read the multiple in RELATIVE terms to its historical trend rather than as a fixed absolute level: a multiple high relative to its long-term MA = overvaluation zone, a low multiple = accumulation zone. Halvings mechanically reduce Thermocap inflation, shifting the multiple's post-halving dynamics.
What to observe
Multiple movement speed is informative. A rapid rise (bubble phase) marks valuation quickly drifting from production cost. A progressive decline (distribution phase) marks a return toward the cost basis. Multiple/price divergences are useful: if price rises but multiple declines, it means Thermocap is growing even faster - intense mining activity absorbing the valuation.
Historical context
Thermocap was introduced by Nic Carter as a measure of cumulative network security investment. The Multiple (MC/Thermocap) is the direct extension creating a relative valuation framework. The concept is analogous to the price/investment ratio in traditional economics: how much does the market value each dollar invested in network security. The multiple's historical trajectory follows a declining envelope (long-term trend) with cyclical oscillations around this trend.
Expert notes
The multiple is NOT bounded by fixed thresholds (no 32x ceiling nor 8x floor). Halvings reduce Thermocap growth rate, mechanically raising the multiple at constant price post-halving. The progressive transition from the block reward model to the fee model will structurally change Thermocap dynamics in coming decades: fees are more volatile than block subsidy, potentially making the multiple noisier.
Common mistakes to avoid
Interpreting fixed absolute thresholds (like 8x / 16x / 32x) as trading zones is an oversimplification. These levels were heuristics from early cycles, but the multiple's actual amplitude has varied significantly across cycles. The multiple must be read in its relative historical context, not as a fixed grid. Additionally, the multiple mixes spot price (Market Cap) with a cumulative measure (Thermocap) - the two are not comparable on the same timescale.
