Starting from March 2020, every time there was a issue of tether, there was rally of btc
first rally was from middle of March, when btc dropped to 3600, and after this begin restore
At binance - starting from middle ofMarch, 2020, difference between total amount of purchased btc and sold btc are negative, but btc are moving up
so problem as for me is - that btc grows up - while the difference between buy and sell volumes is negative
and total volume of this difference corresponds to volume of issued tether
