Tether still bothers me

The banks actually.  Hey, two or three banks, do this. 

Define a bankers coin tied to the dollar and blockchain the crypto coin.  Then, each bank can post, on their web site,  how many dollars are in the crypto account. Is that like, oh wow, difficult? Each bank, do it on their own, or in partnership, do it the same way.

Why? Because there are place where crypto works much better, like on-line sales where blockchain fee is justified, and in auto traded pits where ledger calls can be delayed.  Each bank can brand their own version, add some goodies, and get your trademark on their cash cards.  All the crypto pegs trade at par, unless the banks want to do some auto S&L, which is just fine and dandy.
