USDT is a stablecoin issued by a company called Tether. It's designed to hold a value of one US dollar per coin.
'USDT' and 'Tether' refer to the same coin. USDT is the ticker symbol; Tether is the name of the coin and its issuer.

In practice, the price stays extremely close to one dollar most of the time, with only brief, small deviations during stress.
- Reserves are meant to back circulating coins
- Price usually trades very close to $1
- Small, temporary drift can occur in volatile periods
- Long track record has built strong trading trust
