My problem with this is why doesn't Tether/Bitfinex just at regular intervals publish a list of the banks, their accounts, and the amount they have in each account, with an official statement from the banks in question. I can go down to my local bank and get such a statement verifying my account and it's balance easily enough. Why can't they?
