So i assume that you're going take the official price of gold from NY and London (which we know is rigged). Alternatively, will you do what bytemaster suggests and go 5% above the official price to reflect the real physical price? China is also opening an exchange that may take over from NY/London.
I like the idea though. What sort of annual return would you be expecting your customers to receive?
We will go with whatever price bitgold has. I imagine that in the future when bitgold is better established, delegates will begin to monitor its peg to physical gold directly rather than going gold -> usd -> cny -> bts. So if there ever is a paper decoupling bitgold should not be affected if bitshares is properly established.
It's really hard to say what the expected return per CFSGOLD will be. At first it will be close to zero and the value of holding CFSGOLD will be the CFSCOIN sharedrop. Our target will be to make about 0.3% of pure earnings after fees (if any) and after hedging/arbitrage per trade. So if we have 200k USD volume per day, we will earn 18k USD per month of which 12600 will be distributed to CFSGOLD holders in the form of increased NAV. The question is how much bitgold is required to accomodate 200k volume, and ultimately what's the volume generated per bitgold? There's also some other concerns and even conflicts of interest, because CFSGOLD holders will want the volume per bitgold maximized (which means reducing bitgold supplies and thus CFSGOLD), and CFSCOIN holders will want absolute volume maximized (maximizing bitgold and CFSGOLD supply at the cost of volume per bitgold).
Once we are actually trading it will be possible for us to begin doing analysis on these things and figure out what the best way to deal with it is.
