Summary: Stablecoins are cryptocurrencies pegged 1:1 to a fiat currency (USD, EUR). By depositing stablecoins on lending platforms or DeFi protocols, you earn 4–10% APY with no exposure to crypto price swings. Your €1,000 stays €1,000 — it just earns far more than a bank account.

What are stablecoins?
A stablecoin is a cryptocurrency whose value is pegged to a real-world asset — most commonly the US dollar (USDC, USDT) or the euro (EURC). Unlike Bitcoin or Ethereum, 1 USDC will always be worth approximately $1. This stability is maintained through reserve backing: for every USDC in circulation, Circle (the issuer) holds $1 in US Treasury reserves or cash equivalents.
In 2026, the global stablecoin market has reached $250 billion in total supply — up from $159 billion in 2024. Stablecoins have become the backbone of the crypto economy, used for trading, savings, remittances and increasingly as everyday payment rails.
EU context: Under the EU's MiCA framework, EURC (issued by Circle) is the first fully MiCA-compliant euro stablecoin — meaning it's held to strict reserve and transparency requirements. For European users, EURC is the safest regulatory choice.
How stablecoin yield works
There are three main mechanisms through which stablecoins generate yield:
- Lending: you deposit USDC on a platform like Nexo or Aave. Borrowers (traders, institutions, arbitrageurs) pay to borrow it. You receive their interest payments. The platform or protocol takes a small cut.
- Liquidity provision: you provide USDC to a trading pool on a decentralised exchange. Traders pay fees to swap through the pool; these fees are distributed to liquidity providers.
- T-bill backing: newer stablecoins like USDC now back reserves with US Treasury bills. Some platforms pass this yield directly to holders, creating a low-risk 4–5% base yield.
USDC vs. USDT vs. EURC: which to use?
| Stablecoin | Peg | Issuer | Reserve backing | MiCA compliant | Typical yield |
|---|---|---|---|---|---|
| USDC ⭐ | USD | Circle | US T-bills + cash | Yes | 5–14% APY |
| EURC | EUR | Circle | Euro reserves | Yes (first MiCA) | 4–8% APY |
| USDT | USD | Tether | Mixed reserves | No | 5–14% APY |
| DAI / USDS | USD | Sky (MakerDAO) | Crypto-backed | No | 6–12% APY |
Our recommendation: European users should prioritise USDC and EURC. Both are issued by Circle, a US-listed, audited company, and EURC is the only euro stablecoin with full MiCA compliance in 2026. USDT offers similar yields but Tether's reserve transparency has historically been lower.

Stablecoin savings vs. bank savings account
Here's what €10,000 looks like after 5 years in three different scenarios:
| Scenario | Rate | Year 1 | Year 3 | Year 5 |
|---|---|---|---|---|
| Traditional bank savings | 0.5% | €10,050 | €10,151 | €10,253 |
| Nexo USDC (8% base) | 8% | €10,800 | €12,597 | €14,693 |
| Aave USDC (7%, DeFi) | 7% | €10,700 | €12,250 | €14,026 |
| YouHodler EURC (6%) | 6% | €10,600 | €11,910 | €13,382 |

Risks: what can go wrong?
- Stablecoin de-peg: in rare cases, a stablecoin can lose its peg — as happened with UST/Luna in 2022. USDC and EURC are more resilient due to full reserve backing, but no stablecoin is entirely risk-free.
- Platform insolvency: Celsius, Voyager and BlockFi all collapsed. Only use platforms with verified reserves and regulatory standing.
- Smart contract exploit (DeFi): even audited DeFi protocols have been hacked. Diversify across multiple protocols to reduce single-point-of-failure risk.
- Regulatory changes: MiCA and evolving EU rules could restrict certain stablecoin products or platforms in the future.
- USD/EUR exchange risk: if you earn in USDC (USD) but live in the eurozone, exchange rate fluctuations affect your real return.
Getting started in 4 steps
- Choose your stablecoin. European users: start with USDC for maximum yield options, or EURC to avoid USD/EUR risk.
- Choose your platform. Beginner? Nexo or Coinbase. Want full control? Aave via MetaMask. Want euros? YouHodler's EURC product.
- Fund your account. Transfer euros from your bank to buy stablecoins. All major platforms offer SEPA transfers with zero or minimal fees.
- Deposit and earn. Most platforms start paying interest within 24 hours. Watch your balance compound daily.
