Stablecoins Explained: Why USDT Is Where Most People Start
Published 24 July 2026
Most people assume crypto means wild price swings. Stablecoins are the exception, and for a lot of users they are the whole point.
The idea
A stablecoin is a cryptocurrency designed to hold a steady value โ almost always one US dollar. One USDT should be worth one dollar today, tomorrow, and next year.
You get the mechanics of crypto โ instant, borderless, always on โ without waking up to find your savings worth 30% less.
How they hold the price
Backed by reserves. USDT and USDC work this way. The issuer holds dollars and short-term assets, and issues one token per dollar held. You are trusting the issuer actually holds what they claim, which is why their audit reports matter.
Backed by crypto. Users lock up more crypto than they borrow, so the loan stays covered even if prices fall. No company to trust, but complicated and vulnerable to sharp crashes.
Algorithmic. Code adjusts supply to hold the price. This category has failed repeatedly and spectacularly. Treat with deep suspicion.
Why they get used
- Sending money across borders. Minutes and cents, versus days and percentages.
- Sitting out volatility. Sell into a stablecoin during a crash without leaving crypto entirely.
- Saving in dollars. Where local currency is losing value quickly, this is not a trading strategy. It is protecting what you earned.
- Trading pairs. Most trading happens against a stablecoin rather than against dollars directly.
What to actually watch
The issuer. Reserve-backed stablecoins are only as good as the reserves. Stick to the large, regularly audited ones.
The network. The same USDT exists on several blockchains โ ERC20, TRC20, BEP20. They are not interchangeable in transit. Send TRC20 USDT to an ERC20 address and it is usually gone. Always match the network on both ends.
Small drifts are normal. $0.998 is ordinary. $0.90 means something is wrong and you should pay attention.
