If I had a chance, I will redesign the fee system.
1. change all fee asset from BTS to FEESUSD which belong to committee. all fees will priced on this FEESUSD.
committee only need to sell FEESUSD for bitUSD to increase the supply .
2. all witness and worker will get payment in FEESUSD.
if you don't have faith in Bitshares, or if Bitshares can't get enough users, the FEESUSD is rubbish,
in the other hand, the FEESUSD is exactly 1 USD's worth.
3. no new BTS need create. committee can use bitUSD to buyback BTS and burn it to give back profit to all BTS holders.
