The USDT (United State Dollar Tether) does represent the United States dollar because the value is equivalent to USD and can even be exchanged with FIAT money of any country, but there is a lot of controversy about the USD Theter because they are claimed to fail to conduct an audit of the reserve fund of the USD in its possession so that not worth representing stable coin or USD digital. If viewed from the purpose of creating this USDT it is indeed to facilitate the transfer of money across countries and make coins of a stable value so that it is not uncommon to be used as an alternative by the coiner when there is a cryptocurency storm. Another polemic was when New York Attorney General Letitia James accused Theter of hiding large losses from investor funds.
