So recently, there has been some discussion about fee schedules. I believe the BTS needs to raise fees in a sustainable way. What exactly this means, well, it is complicated. One way we might be able to backwards figure out what fee to charge is look at the total cost/budget we want for the BitShares blockchain, and then divide that by the actual (not an inflated) number. Another way is to look at what competitors are charging. There are lots of factors to take into account. The average credit card transaction pays a about $1.50 in transactions fees (mostly paid by merchant.)
