My understanding is that US Treasury issues a bit more than 1000 billion USD worth T-bills each month. If this is true, Tether must be one of the largest T-bill purcahser (multiple percentages of total issuance every month). Count me sceptic. Somehow I would assume this would be big news in finacial world. Edit: how do they claim bying them? I thought they had no us banking access?
