What Happens to a Bitcoin Treasury if Bitcoin Falls 50%?

Input	Scenario definition
Baseline	Hypothetical: 100 units, 20 Bitcoin, 80 cash, floor 80
Bitcoin price shock	A 50% decline from the stated starting level
Bitcoin quantity	Held constant in the static case
Cash and liabilities	Unchanged; no cash flows, financing, taxes or transaction costs
Constraint	A defined fixed reserve-value floor
Interpretation	Conditional balance-sheet sensitivity, not a probability estimate

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	10 units
Ending reserve	90 units
Floor headroom	10 units
Floor status	Above the floor
Allocation cap	20% allocation is within the 40.0% cap for this decline

If Bitcoin represents a fraction a of starting reserves and cash is unchanged, the direct reserve loss fraction is a × 0.50. A company with a small unleveraged position has a different exposure from one whose reserves are almost entirely Bitcoin.

A hypothetical 100-unit reserve containing 20 units of Bitcoin and 80 of cash falls to 90 units under this shock. The ten-unit loss is 10% of initial reserves, although Bitcoin itself lost half its value. This example establishes neither a safe allocation nor a recommendation to hold that amount.

Let starting reserve be T and the fixed floor be F. Under the simple cash-and-Bitcoin assumptions, post-shock reserve is T × (1 - 0.50 × a). The condition for ending at or above the floor is a <= (1 - F/T) / 0.50, subject to valid positive T and a constrained to the unleveraged interval from zero to one.

If the reserve begins below the floor, no nonnegative Bitcoin allocation repairs that initial gap under a loss-only scenario. If the computed cap exceeds one, the full unleveraged allocation meets this particular floor at this shock; it is not universally safe. Exact equality reaches the floor with no remaining headroom.

Selling Bitcoin converts assets into cash but does not restore total reserve value by itself. Whether a company must sell depends on cash needs, covenants, collateral terms, and access to financing or other assets. A reserve-floor equation is a policy constraint rather than a complete account of those conditions.

A company might meet the floor but face a payment before sale proceeds settle. Alternatively, it might breach an internal reserve policy without facing immediate insolvency. The scenario keeps those conclusions separate.

The basic shock excludes costs, tax, outflows, revenue changes, and borrowing. A starting Bitcoin price is needed to translate the percentage shock into a price, but not to calculate proportional reserve loss. At zero Bitcoin exposure there is no meaningful Bitcoin break-even price for the treasury; infinity is not a valid result.

The 50% shock is selected for analysis, not assigned a likelihood. Static cash understates risk if operating conditions weaken at the same time. An unchanged share count or treasury asset value does not imply an unchanged stock price. The result cannot measure liquidity timing or contractual liquidation without their separate inputs.

Translate the Bitcoin shock into the company's actual reserve exposure before judging severity. Then ask whether the tested floor is the constraint that really governs the next required action.
