USDT is the most trusted cryptocurrency among others. It's even safer than Bitcoin iteslf. Usually, they call Bitcoin gold, but I'd say that USDT is real gold. It's stable so if you want to have smth constant in crypto, hold this stablecoin.
Never found information from the Tether team's statement that the usdt was backed by gold and even many doubts have arisen lately that 1 usdt represents 1 dollar. The fact is they are still volatile.
