What is Stablecoin?
The appearance of Bitcoin in 2009 allowed us to look at the financial market from a completely different perspective. Hundreds of new cryptocurrencies have been created since 2010, but price volatility limited widespread adoption. Stablecoins emerged to reduce that volatility by pegging value to fiat currencies or other assets.
Stablecoins aim to provide fixed prices. Given the great volatility of the market, cryptocurrencies do not allow maintaining the size of an investment portfolio or multiplying it in the long term. Stablecoins offer investors relative stability, making it easier to secure profits, wait out volatile periods, or use digital assets for everyday purchases.
What are stablecoins?
Stablecoins are digital assets designed to maintain a stable value relative to a reference asset, commonly fiat currencies like the US dollar or euro. They run on blockchains and combine benefits of cryptocurrencies (transparency, security) with reduced price swings compared to typical cryptocurrencies.
Some stablecoins are backed 1:1 by fiat reserves held by issuers. Others are collateralized with cryptocurrencies, and a third class uses algorithms and smart contracts to manage supply. The stability mechanism varies by design and affects decentralization, risk, and regulatory exposure.
How does a stablecoin work?
Stablecoins generally achieve stability in one of three ways:
- Fiat-collateralized stablecoins
- Crypto-collateralized stablecoins
- Algorithmic stablecoins
Fiat-collateralized stablecoins
These are backed 1:1 by fiat currency reserves (for example USD or EUR) held by a custodian. The issuer mints stablecoins when fiat is deposited and redeems them when fiat is withdrawn, aiming to keep the peg.
Crypto-collateralized stablecoins
Crypto-collateralized stablecoins are backed by other cryptocurrencies. They are often over-collateralized to absorb price swings in the backing assets and may operate via decentralized protocols without a central administrator.
Algorithmic stablecoins
Algorithmic stablecoins use smart contracts to automatically expand or contract supply in response to demand, instead of holding collateral. Their stability depends on the effectiveness of protocol rules and market confidence.

Future of stablecoins in the cryptocurrency market
Stablecoins sit between decentralized cryptocurrencies and centrally managed fiat money. Financial institutions and regulators increasingly influence these instruments as they gain adoption, which shapes their regulatory treatment and integration into traditional finance. For historical context, see our page on Bitcoin.
Most used stablecoins
Tether (USDT) is the largest by trading volume and market capitalization. USD Coin (USDC), Paxos Standard (PAX) and Binance USD (BUSD) are also widely used, often implemented on Ethereum as ERC‑20 tokens or on other blockchains for faster transactions.
Advantages of stablecoins
Stablecoins reduce volatility, enable faster and more transparent transfers than traditional banking, and let users secure gains by converting volatile holdings into a more stable digital asset. They can also facilitate cross-border payments and digital commerce.
Disadvantages of stablecoins
Risks include reserve transparency and centralization for fiat-backed coins, smart contract and design failure for crypto-backed or algorithmic stablecoins, and regulatory intervention that can limit circulation. Liquidity can vary across stablecoins and markets.
