🧠 *Day 4 of learning crypto — Why does everyone use USDT?

When I first started seeing crypto prices, I kept seeing something everywhere:

USDT

And I had a very basic question:

"If crypto is supposed to be volatile, why does USDT try to stay around $1? 🤔

Here's what I learned.

USDT = Tether USD₮

It's a stablecoin — a type of cryptocurrency designed to maintain a stable value relative to the U.S. dollar.

So unlike $BTC or $ETH, which can move significantly in price, USDT is designed to stay close to:

1 USDT ≈ 1 USD

That's why you'll often see trading pairs like:

BTC/USDT
ETH/USDT

Think of USDT as a kind of digital dollar representation used inside the crypto ecosystem.

It can be transferred between supported wallets and used for trading and other crypto activities.

But here's something I REALLY want to remember as a beginner:

⚠️ Stable ≠ risk-free.

A stablecoin has a different risk profile from something like $BTC, but that doesn't mean there are zero risks.

There can be:

• Issuer/counterparty risk
• Regulatory risk
• Network/transfer risks
• Temporary price deviations
• Risks depending on where and how you hold it

Ethereum.org also points out that fiat-backed stablecoins involve centralized issuers and require confidence that sufficient reserves exist.

Tether says USD₮ tokens are backed by reserves and that eligible customers can redeem them subject to Tether's terms.
