Stablecoin
Etymology
A compound of "stable" and "coin," contrasting with the wild swings of assets like Bitcoin. It emerged in the mid-2010s; some stablecoins hold real reserves, while "algorithmic" ones try to hold their peg through code alone — a design that has collapsed spectacularly, so the "stable" label is a claim, not a guarantee.
noun · /STAY-bul-koyn/
A cryptocurrency designed to hold a steady value by pegging to a reserve asset like the US dollar.
What it names
Crypto’s attempt to solve its own volatility problem — a digital token meant to behave like cash — now central to how the ecosystem actually moves money.
Example
Traders park funds in a stablecoin between bets to avoid the market’s day-to-day swings.
Related idea
Distinct from a central bank digital currency, which is government-issued; a stablecoin is a private token that merely tracks a currency’s value.
