Measuring success: BTC yield, NAV, and the fiat illusion
If you keep score in the currency you are leaving, you will abandon the strategy at the exact moment it is working.
Helena Voss, Guest, Helios Industrial CFO
Two ledgers, one truth
Accounting will report Bitcoin in dollars because the reporting currency is dollars. Strategy should report Bitcoin in Bitcoin because the asset’s monetary premium is the point. We keep both ledgers and we never let the first one fire the CIO.
BTC yield is the simplest adult metric: change in BTC held relative to the capital raised or cash converted to acquire it, adjusted for fully diluted shares. A quarter where the stock is down and BTC per share is up is a good quarter. A quarter where NAV in dollars is up because you issued stock at a panic multiple and bought nothing is not.
NAV is a translation, not a god
Net asset value in fiat is useful for lenders, auditors, and the night desk. It is a terrible north star. It spikes when the market is euphoric and collapses when the market is offering you coins. If your compensation plan is tied only to fiat NAV, you have hired people to sell bottoms.
We recommend a scorecard with four numbers, every month: BTC held, BTC per share, months of opex covered by the cash sleeve, and a scenario NAV at the cycle-low price the board pre-committed to survive. Everything else is commentary.
The illusion you can opt out of
The fiat illusion is the belief that because the unit of account is stable on a screen, it is stable in the world. Energy, housing, and semiconductor fabrication costs have been voting against that belief for a decade. Bitcoin is how a treasury opts out without leaving the corporate form. Measure the opt-out in the asset you opted into. The rest is conversion arithmetic.
