Tether (USDT) is a digital currency whose value always corresponds to the value of the US dollar. Tether was launched in 2014. The idea was to create a stable cryptocurrency that could be used as a digital dollar or "stablecoin". Tether is pegged (from English to tether) to the price of the US dollar. Launched in 2014, Tether (USD₮) tokens were the first in the stablecoin model and are the most popular. Tether tokens offer the stability and simplicity of fiat currencies combined with the innovative nature of blockchain technology, representing the perfect combination of both worlds. In addition to bitcoin, USDT was later updated to work on the Ethereum, BNB, Tron, Algorand, and OMG blockchains.
