Maybe a more sophisticated method of drawing up conversion rates would help?
The rates I post at
http://galaxies.mygamesonline.org/digitalisassets.html do not take volume into account, so when for example mining corps ship fifty million units of "Deuterium" to a depot it seems very likely that for some currencies/assets the prices listed are not really reflecting very well what would happen if you actually went to an exchange and tried to buy or sell that amount of that asset.
Also of course the mere fact that conversion rates exist at all insulates the exchanges from such conversions; many debtors whose outstanding loans are denominated in DeVCoin have been failing to impact the exchange rates due to the accounting between the corps they sell raw materials to and the corps they owe DeVCoins to being mediated by "conversion rates".
The corp buying the deuterium and the corp holding the miner's debt both use the same conversion chart, the one at
http://galaxies.mygamesonline.org/latestrates.inc (which incidentally has not been updated in a while so is actually somewhat out of date today).
For example suppose 50 million units of deuterium is delivered to a General Mining Corp depot today. General Mining corp pays, at today's listed price (which actually dates back to May 1st, as I mentioned these tables have not been updated frequently lately), 0.07731018 GMC per thousand units, which is listed in the same row of the table as being equivalent to 88495.57522123 DVC per thousand units.
The thing is, GMC does not go out to an exchange and buy (88495.57522123 x 50000 = 4424778761.06150000) DVC to pay to the loan-holder as payment against the miner's debt. Rather, they simply pay the loan-holder the supposed equivalent in some currency they find more convenient, which of course for General Mining Corp (GMC) quite often turns out to be GMC coin. So they send the lender (0.07731018 x 50000 = 3865.50900000) GMC instead for example, and the lender credits the miner the supposedly-corresponding number of DeVCoins, that is, 4424778761.06150000 DVC, against the miner's loan. (Minus any transaction fees or service fees etc of course.)
Of course when the miners who at some point chose to switch their debts over to a finance corp that allowed them to have their debts denominated in DeVCoins, this same kind of conversion took place. For example General Finance Corp did not send General Mining Corp hundreds or thousands of billions of DeVCoins (there are less than ten billion DeVCoins in existence so far as I write this) when it bought the GMC-denominated debts of certain miners, instead it bought them using GMC coins.
Considering that just one shipment of fifty million units of deuterium turns out to be a more than four point four billion DeVCoin value transaction, it seems clear that the liquidity on exchanges or sheer number of DeVCoins in existence needs to be way the heck higher so that miners and corps can throw such numbers of coins around just in the course of their day to day delivering-stuff-to-depots OR DeVCoins need to be worth a whole lot more deuterium per coin before the exchanges are likely to be of much use in conducting such business...
