3. Tether- USDT
When Tether, formerly known as Real coin, was founded in 2014, it was one of the first cryptocurrencies to be linked to the US dollar. Tether is a cryptocurrency whose crypto tokens are backed by an equal amount of traditional fiat currencies, such as the dollar, pound, or Japanese yen, held in a separate bank account. Tether is a stable coin, a type of cryptocurrency that aims to keep cryptocurrency prices stable, rather than the large price swings seen in other popular cryptocurrencies like Bitcoin and Ethereum.
