$USDC Tether (USDT) is a stable cryptocurrency, which means its value is designed to remain close to that of a fiat currency, in this case, the US dollar. Launched in 2014, it has become the most used stablecoin in the cryptocurrency world, noted for its liquidity and wide adoption in exchanges.
Its main function is to provide stability in a market known for its volatility. Each USDT in circulation is theoretically backed by an equivalent amount in reserves, although this has been the subject of debate and audits.
USDT facilitates cryptocurrency trading by allowing traders to move between different digital assets without having to convert back to fiat money. It is also used for payments and transfers, offering an alternative to traditional currencies in the digital space. Despite some controversy in the past, USDT remains a fundamental piece in the crypto ecosystem.
