Frequently Asked Questions About Stablecoins

What is a stablecoin?

A stablecoin is a cryptocurrency designed to maintain a stable value relative to a reference asset, typically the US dollar. Unlike Bitcoin or Ethereum, which can fluctuate significantly, stablecoins aim to stay at $1.00. They achieve this through various mechanisms including fiat reserves (USDT, USDC), crypto collateral (DAI), or algorithmic supply adjustments.

What is the largest stablecoin by market cap?

Tether (USDT) is the largest stablecoin with a market cap exceeding $140 billion as of 2025. USDC (Circle) is the second largest at around $50 billion. Together, USDT and USDC account for over 85% of the total stablecoin market capitalization.

How do I earn interest on stablecoins?

You can earn interest on stablecoins by lending them on DeFi protocols like Aave or Compound, depositing them in CeFi platforms like Nexo or YouHodler, or providing liquidity on decentralized exchanges. APY rates typically range from 3% to 12% depending on the platform and market conditions. Bitcompare tracks the best stablecoin lending rates across 50+ platforms.

What is peg stability and why does it matter?

Peg stability measures how closely a stablecoin maintains its target price (usually $1.00). A stablecoin with high peg stability rarely deviates more than 0.1% from $1.00, while poor stability may see fluctuations of 1-5% or more. Peg stability is crucial for traders and DeFi users who rely on stablecoins to preserve value and execute precise trades.

What are the different types of stablecoins?

There are four main types: (1) Fiat-backed stablecoins like USDC and USDT are backed 1:1 by cash or cash equivalents. (2) Crypto-backed stablecoins like DAI are overcollateralized with cryptocurrencies. (3) Algorithmic stablecoins use smart contracts to control supply. (4) Commodity-backed stablecoins like PAXG are backed by physical assets like gold.

Are stablecoins safe?

Stablecoin safety depends on the issuer, reserve transparency, and regulatory compliance. Major stablecoins like USDC publish regular attestation reports from accounting firms. Risks include depegging events (like UST in 2022), regulatory action, or reserve mismanagement. Always check the transparency grade and audit frequency before holding large amounts.

Which stablecoins are available on multiple blockchains?

Most major stablecoins are multichain. USDT exists on Ethereum, Tron, Solana, Avalanche, and 10+ other networks. USDC is available on Ethereum, Solana, Base, Arbitrum, Polygon, and more. Multichain availability improves liquidity and allows users to choose networks with lower fees.

How often is the Stablecoin Index updated?

The Bitcompare Stablecoin Index updates market cap, volume, and peg price data every 5 minutes. Stability scores and grades are recalculated hourly based on 30-day peg deviation history. Reserve transparency and audit information is updated when issuers publish new reports.
