Use optional ad revenue to lower fees.

[luckybit]

A person who wants lower fees should be given the option to accept advertisements. In exchange their fees could be lowered and the ad revenue could go toward purchasing and burning BTS.

I notice many participants in China and other places expect it to be free or nearly free. Offer a freemium model for people who want lower fees but do not lower the profits of Bitshares. All transactions should be paid for one way or another.
