I also believed that the USDT and TUSD are stable coins, which can differ from one dollar by several hundredths of a percent, not more. However, the other day I was surprised when I saw the USDT rate at $ 0.85, and the TUSD, which has the rate then from 1.24 to 1.10 dollars. At the same time, bitcoin jumped in price by about $ 1,500 for about three hours. That is, stable coins still can deviate so much from one?
