Stablecoins are the quiet workhorses of crypto. While Bitcoin and Ethereum swing in value, stablecoins are designed to stay pinned to $1, giving traders a safe harbor and a way to move money without leaving the crypto ecosystem. But not all stablecoins are built the same way — and the differences matter.
Why stablecoins exist
Volatility makes crypto hard to use as money. Stablecoins solve that by tracking a stable asset, usually the US dollar. They let you park funds during a downturn, settle trades instantly, and access decentralized finance — all without converting back to a bank account. They now settle trillions of dollars in transactions every year.
USDT and USDC: backed by reserves
Tether (USDT) and USD Coin (USDC) are fiat-collateralized: each token is meant to be backed by real dollars and equivalents held in reserve. USDT is the largest and most widely traded; USDC is known for regular attestations and a compliance-first reputation. The key question for both is always the same — are the reserves real, liquid, and fully audited?
DAI: backed by crypto
DAI takes a different path. It is crypto-collateralized and decentralized: users lock up crypto assets in smart contracts to mint DAI, with the system over-collateralized to absorb price swings. No company holds the reserves — code and collateral do. That removes single-company risk but adds smart-contract and collateral-volatility risk.

The risks behind the calm
A stablecoin is only as stable as its backing. De-pegs happen when confidence cracks or reserves are doubted, and algorithmic designs without real collateral have collapsed entirely. Spread risk across issuers, prefer transparent reserves, and never assume $1 is guaranteed. Understanding market capitalisation helps you gauge how systemically important a stablecoin has become.
The bottom line
Stablecoins make crypto usable, but the word “stable” is a goal, not a promise. Know whether your stablecoin is backed by dollars, crypto, or merely an algorithm, watch the transparency of its reserves, and you can use them with confidence. Browse the wider market on our coins page.
