It's not surprising. Liberals want the government to take money from people to fund itself. A digital currency allows them to do that much more efficiently.
Negative interest is supposed to be applied on cash and bank reserves (this includes checking accounts). Not on savings accounts.
The entire point of negative interest rates is to get people to stop holding 70% of their balances at the bank in checking accounts. Because checking accounts cannot be used for loans, the bank creates new money which lands on another checking account which repeats endlessly like some sort of out of control recursive function resulting in a perpetual increase in the M1 money supply.
