Stablecoin
A cryptocurrency designed to hold a steady value, usually pegged to a currency like the US dollar.
A stablecoin is a cryptocurrency built to hold a steady value, usually pegged one-to-one to a national currency like the US dollar. One unit aims to be worth one dollar, today and next month. That fixed target is the whole point. It strips out the day-to-day price swings that define most crypto.
Why would anyone want crypto that does not move? Because the movement is often the problem. If you want to park funds between trades, settle a payment, or hold value on-chain without watching a chart every 5 minutes, a coin that stays near a dollar does the job. Traders use them as a home base. People in countries with high inflation use them to hold something steadier than the local note.
The two largest are Tether (USDT), launched in 2014, and USD Coin (USDC), launched in 2018. Both claim each coin is backed by reserves: dollars, short-term government debt and similar assets held off-chain. Together they account for well over $100 billion in circulation. The model is easy to state and hard to run. The peg only holds as long as the market trusts that the reserves are real and that holders can redeem at face value.
Not all stablecoins work the same way. Reserve-backed coins hold real assets. Algorithmic ones tried to hold the peg with code and a paired token instead of cash. That second design has a brutal track record. In May 2022 the algorithmic coin UST lost its dollar peg and collapsed alongside its sister token LUNA, erasing tens of billions in days. Backing matters.
For someone buying through an on-ramp, a stablecoin is often the first stop. You convert cash to a dollar-pegged coin, then move into other assets when you choose, sidestepping the volatility of holding bitcoin while you decide. A stablecoin is steady, not risk-free. The peg depends on the issuer and the reserves behind it, so read who stands behind the coin before you trust it.
