What Happens to a Bitcoin Treasury if Bitcoin Falls 70%?

Input	Scenario definition
Approved baseline	Hypothetical: 100 units, 20 Bitcoin, 80 cash, floor 80
Bitcoin shock	A 70% price decline
Static quantity	No purchases or sales during the immediate shock
Reserve floor	Fixed at 80 units
Other changes	No cash flows, financing, taxes or transaction costs
Purpose	Severe sensitivity test, not a historical return claim

Illustrative calculation on a hypothetical baseline: 100 units of reserves, 20 in Bitcoin, 80 in cash, a floor of 80, cash unchanged, and no cash flows, financing, taxes or costs. These are not company figures or market results.

Measure	Result
Starting reserve	100 units
Bitcoin initial value	20 units
Cash initial value	80 units
Reserve floor	80 units
Stressed Bitcoin value	6 units
Ending reserve	86 units
Floor headroom	6 units
Floor status	Above the floor
Allocation cap	20% allocation is within the 28.6% cap for this decline

For accessible cash C and initial Bitcoin value B, post-shock reserve is C + 0.30 × B before costs. Subtracting the fixed floor F gives headroom. A negative value means the chosen reserve constraint fails in the scenario; it does not by itself establish legal insolvency.

On the hypothetical baseline, C = 80, B = 20 and F = 80: reserves fall from 100 to 86 and headroom is 6. Because cash alone equals the floor, only a total loss of the Bitcoin value would bring reserves exactly to the floor. A baseline with more Bitcoin and less cash would cross the floor at a smaller decline. These are illustrative inputs, not figures for an actual company.

The example measures terminal reserve value at the stressed price. It does not identify the date of a payroll shortfall or a debt default. Those events require a dated forecast of accessible cash, receipts, payments, and contractual terms.

A financing assumption can dominate the outcome. Counting an uncommitted equity raise as certain cash would weaken the stress precisely when adverse markets may restrict fundraising. A separate combined-stress analysis can examine closed capital markets or reduced revenue, but those outcomes are not supplied by the static equation.

A concentrated but unleveraged reserve may suffer a large mark-to-market loss without triggering a lender's sale. Pledged Bitcoin introduces a separate collateral test with its own haircut, cure period, and liquidation rule. Treating these two cases as identical hides the mechanism that could force action.

The scenario's allocation constraint depends on the selected 70% shock. Reusing a cap from another drawdown would give the wrong boundary. Labels refer to reserves at or above the stated floor, not to a universally safe corporate allocation.

The static illustration leaves cash unchanged and excludes execution costs and tax. A sale during stressed markets can realize less than the reference valuation. Missing restrictions or obligations cannot be filled with zero. If no Bitcoin is held, the model reports that the price shock has no direct Bitcoin effect rather than inventing a breaking price.

A severe percentage decline is not a forecast or a calibrated probability. Business deterioration, inaccessible custody, and intraday margin calls can make a real outcome worse. Conversely, an internal policy breach is not identical to inability to pay. The result applies only to the defined reserve pool and floor.

Use the 70% case to locate the reserve constraint, then investigate the separate cash and contractual pressures around it. A single balance-sheet result cannot describe every route to forced action.
