If they printed 2 billion tethers and bought them all back at 99 cents each (which is realistic, because tether typically floats at basically a dollar), that would only be $20,000,000. If they get 5% per annum on the float from just keeping the cash in the bank, that's $100,000,000. So I'm not sure what's best to do in typical circumstances. There have been ~two historical exceptions. From April 20 - May 20, 2017, they could have absolutely cleaned up by buying their own tethers back. Hundreds of millions of dollars of tethers were traded at an average price of 95 cents or so.
