What is a stablecoin?
A stablecoin is a cryptocurrency designed to hold a steady value — almost always about $1. The best-known are Tether (USDT) and USD Coin (USDC).
Why would you want a coin that doesn't move?
Stablecoins are the "cash" of crypto. Traders park money in them between trades without cashing out to a bank, and people use them to send dollars across the world quickly. Because they don't swing like Bitcoin, they're used for stability, not growth.
How do they stay at $1?
Most are backed by reserves — real dollars, bonds, or similar assets — that the issuer holds to match the coins in circulation. Others use algorithms. The key question is always: is it actually backed, and by what?
The risk people forget
"Stable" doesn't mean "risk-free." A stablecoin can lose its $1 peg ("de-peg") if its backing is doubtful or the market panics — which has happened before. Understanding what backs a stablecoin matters more than its steady price.
Frequently asked
What is a stablecoin?
A stablecoin is a crypto token designed to hold a steady value, usually pegged to a currency like the US dollar. It aims to combine crypto's speed with cash-like stability.
Are stablecoins actually stable?
Usually, but it is not guaranteed. Some stablecoins have lost their peg (a 'depeg'), and the quality of what backs them varies a lot, so they carry real risk.
What are stablecoins used for?
They let people move value and sit in a steadier asset without leaving the crypto ecosystem, and they act as a base pair for trading and DeFi.
