Fixed Cost

A fixed cost is a business expense that does not vary with output in the short run, such as rent, insurance, equipment depreciation, and salaried staff, in contrast to variable costs like raw materials and electricity that scale with production. A factory paying 100,000 dollars in monthly rent owes it whether it produces one unit or one million.

Why it matters

The ratio of fixed to variable costs defines an industry's character. High fixed costs create operating leverage, where small revenue changes swing profits violently, and they create barriers to entry, since challengers must commit capital before earning anything. Both monetary metals and bitcoin mining are textbook high fixed cost industries. A gold mine requires years and often billions of dollars of development before the first ounce; a bitcoin mining operation sinks capital into ASIC hardware and facilities that depreciate quickly, then competes on the variable cost of electricity. In each case, when prices fall below all-in costs, high cost producers shut down first, which historically firms up supply.

In the gold vs bitcoin debate

Cost structure is where the unforgeable costliness of both assets lives: each is expensive to produce, which is precisely what protects them from cheap issuance. The difference is what the cost buys. Gold's production costs add ounces to a stock that grows regardless of need, while bitcoin's mining costs buy security for a supply schedule that never changes, with the difficulty adjustment ensuring that more spending produces more security, never more coins.
