Float

Float has two principal financial meanings. A floating currency is one whose exchange rate is set by market supply and demand rather than a government peg, the regime major currencies have followed since fixed rates collapsed in 1973. In markets, float is the portion of an asset's supply actually available for trading, excluding locked, insider, or long dormant holdings.

Why it matters

The float era is the water modern finance swims in. After President Nixon suspended dollar gold convertibility in August 1971 and the Bretton Woods system unwound, money's value became purely relative, each currency floating against the others with no external anchor. Every inflation hedge debate since is downstream of that change. The market sense of float matters for price behavior: when tradable supply is thin, incremental demand moves prices sharply. Analysts estimate a meaningful share of bitcoin, often put at several million coins, is lost or held by entities that never sell, and exchange balances shrank through the early 2020s, meaning bitcoin's effective float is far below its 19.5 million mined coins.

In the gold vs bitcoin debate

Gold and bitcoin are the two serious candidates for the anchor the float era removed, and their float dynamics differ tellingly. Most of gold's roughly 210,000 tonne stock sits in jewelry, central banks, and vaults, surfacing when prices spike; bitcoin's dormant supply is publicly visible on-chain, letting analysts watch long term holders accumulate or distribute in real time. Scarcity claims about either asset are really claims about float, not just total supply.
