Stablecoin Types

Not all stablecoins are created equal. They differ in how they maintain their peg—and that affects their risk profile, decentralization, and use cases.

🏛️ Three Types of Stablecoins

Fiat-Backed Stablecoins

Backed 1:1 by real dollars held in bank accounts. The simplest model but requires trusting the issuer.

HOW IT WORKS
  • • Company holds $1 in bank for each token
  • • Users can redeem tokens for real USD
  • • Regular audits verify reserves

Managing Risks

Stablecoins aren't risk-free. Understanding the risks helps you protect your funds and make informed choices.

🔻 Depeg Event Simulation

A "depeg" is when a stablecoin loses its $1 peg. Watch what happens during a crisis:

$1.000
✓ Stable
$0.85$1.00 (Target)$1.05

⚠️ Real example: In March 2023, USDC briefly dropped to $0.87 when Silicon Valley Bank (holding $3.3B of reserves) collapsed. It recovered within days, but holders experienced temporary losses.

🛡️ Safety Best Practices
  • Diversify: Don't put all funds in one stablecoin
  • Research: Check reserve reports and audit history
  • Monitor: Watch for news about issuers and peg stability
  • Limit exposure: Only hold what you need for near-term use

Common Mistakes & Gotchas

These misconceptions can cost you money. Learn from others' mistakes:

⚖️
All stablecoins are the same, just pick any
Each stablecoin has different backing, risks, and decentralization levels. USDC ≠ USDT ≠ DAI.
💥
Algorithmic stables are fine, they're just innovative
Algorithmic stablecoins have failed spectacularly (UST/Luna). Understand the mechanism before using.
🔗
USDT on Tron is the same as USDT on Ethereum
Same token, different chains. Fees, speeds, and security vary. Don't send to wrong network!
🛡️
My stablecoins are 100% safe, they're stable!
Stablecoins have risks: depegs, issuer bankruptcy, smart contract bugs, frozen addresses.

⚠️ Remember: "Stable" doesn't mean "risk-free." Even the biggest stablecoins have experienced depegs, regulatory issues, and technical problems. Stay informed.
