In addition to RSI, the price of USDT also has some patterns during fluctuations. Since around November last year, USDT has been in a prolonged state of discount. Only from November 28 to December 16 did the price of USDT remain above 1 dollar. On January 6 and January 15, the price briefly approached 1 dollar. On February 25, it reached a peak of 1.0004, then fluctuated near 1 dollar. Several peaks in the price of USDT generally correspond to the peaks of BTC. Of course, the peaks in the price of USDT may occur a bit earlier, as funds need to enter the market before they can flow into BTC.
