With 15 billions UST in deposit, if 1 ANC was purchased and deposited in the protocol for each 1000 UST, we will have 15 Millions bANC to be used by the protocol to generate staking incomes like we do with bLuna and bEth.
Why not asking that small investment ratio to every earn depositor? They will own the bANC but wont be able to take it out of the protocol unless they withdraw their deposit.
