Saleability

Saleability, also written salability or marketability, is the ease with which a good can be sold at close to its market price whenever the owner chooses. The economist Carl Menger placed it at the center of his 1892 account of the origin of money, arguing that money simply is the most saleable good in an economy, the one accepted with the smallest discount in any trade.

Why it matters

Menger's insight explains monetization as a market process rather than a state decree: traders converge on whichever good sells most reliably, and that convergence feeds on itself. Saleability has three dimensions. Across space, a good must move cheaply, favoring high value per weight. Across time, it must hold value between receipt and spending, favoring durability and scarcity. Across scale, it must divide into large and small transactions without losing value per unit. Gold's dominance came from scoring well on all three against every rival commodity.

In the gold vs bitcoin debate

The modern debate is often conducted in Menger's terms. Bitcoin arguably dominates across space, moving any value worldwide within the hour, and across scale, dividing to one hundred millionth of a coin, while gold requires shipping and cannot practically settle small amounts in physical form. Across time the comparison inverts: gold has held value over centuries while bitcoin's 16-year record includes drawdowns exceeding 75 percent. Each side extrapolates its strength, and the market's verdict, measured in relative capitalization, is still being written.
