What is USDT (Tether)?

USDT, also known as Tether, is a stablecoin — a type of cryptocurrency designed to maintain a 1:1 peg with the US dollar. Each USDT token is backed by reserves held by Tether Limited, meaning 1 USDT should always be worth approximately $1 USD.

In Latin America and Africa, USDT has become the most popular way to hold dollar-denominated value without needing a US bank account. It trades on virtually every crypto exchange and can be sent peer-to-peer in seconds at minimal cost.

Which Blockchain Should I Use?

USDT is available on multiple blockchain networks including Ethereum (ERC-20), Tron (TRC-20), and Solana. The TRC-20 version is most popular in emerging markets due to its low transaction fees — often less than $1 per transfer regardless of amount.

How Does USDT Compare to Other Stablecoins?

Other popular stablecoins include USDC (by Circle/Coinbase) and DAI (a decentralised stablecoin). USDT leads in liquidity and exchange support, especially in LATAM and Africa. Cambialo tracks all of these across 20+ exchanges so you can find the best rates.

How to Buy USDT

The cheapest way to buy USDT depends on your country. In Argentina, local exchanges often offer competitive ARS rates. In Nigeria, P2P platforms dominate. Binance is available in most markets and consistently offers some of the lowest fees globally.
