What USDT Is and Why It Matters
USDT is a stablecoin pegged to the dollar. Here's what it's used for, why the price stays stable, and why picking the right network matters every time you transfer it.

USDT (Tether) is a stablecoin: a cryptocurrency whose price stays close to one US dollar. It moves like any other crypto, fast, over the blockchain, without a bank. That combination of dollar stability and crypto-speed is why USDT shows up in more payments, savings, and exchanges than almost anything else.
Why doesn't USDT drop in price like Bitcoin?
Tether Limited, the company that issues USDT, holds reserves that back the coins in circulation. The peg to one dollar is maintained through those reserves. Stable price, crypto-speed transfers. That's the core idea behind stablecoins.
What do people use USDT for?
Transfers and payments: sending money quickly without touching the banking system and without betting on Bitcoin's price. Holding value: staying out of volatile coins without cashing out to a bank account. Swapping: many exchange pairs route through USDT because it's the most liquid common denominator between other coins.
What are TRC20, ERC20, and BEP20?
USDT exists on several blockchains at the same time. TRC20 (Tron network) is the most popular for payments: transfer fees are tiny and speed is high. ERC20 (Ethereum) costs more but is accepted everywhere. BEP20 (BNB Chain) is cheap but less widely supported. Same coin, different rails.
Picking the right network
Sending USDT on TRC20 to an ERC20 address means losing the money. Before any transfer, confirm that the sender's network matches the receiver's network. That's the single most important rule when working with USDT.
