Capital Expenditure

Capital expenditure, or capex, is money a business spends to acquire or upgrade long-lived assets such as land, buildings, and machinery, as distinct from day-to-day operating costs. Capex is recorded on the balance sheet and depreciated over the asset's useful life. A single modern ASIC bitcoin miner costs several thousand dollars, and industrial mining facilities run to hundreds of millions.

Why it matters

Capital intensity shapes an industry's structure. High upfront spending creates barriers to entry, forces long planning horizons, and makes producers acutely sensitive to financing conditions and commodity prices. Analysts watch the ratio of capex to depreciation to judge whether a company is growing or merely maintaining itself, and free cash flow, the profit left after capex, is a standard measure of what a business actually produces for its owners.

In the gold vs bitcoin debate

Both monetary metals and bitcoin are secured by enormous capital expenditure. Developing a major new gold mine can require more than 1 billion dollars and a decade of lead time before first production, which is why gold supply barely responds to price. Bitcoin mining runs on a faster cycle: ASIC fleets depreciate in a few years and each halving cuts revenue per block, forcing continual reinvestment. In both cases, heavy capex is not waste but the cost of making new supply hard to produce.
