Thanks for finding and reporting all of this information so concisely. I've been aware and waiting for someone to do this!
It's a tough one, as in ideal world 'fee free' would be something amazing, but instead of embarrassing myself trying, can anyone elaborate on alternative ways for DAC to make money/build reserves? I've heard things like fee-backed smart assets / bitassets. Basic question - what other activities are worth further study, which BitShares Blockchain could use further expand reserve pool?
Above - Not to detract from the main topic - these fees now are clearly not sustainable....One thing is for sure, glad to have you around @clockwork, I can already vouch for you around this community for a while as very capable of the sums, I'm highly supportive of what you come up with as the best means of getting these reserves self-sustainable or to grow.
