Hi @BitSense Informatics
Nice to see more BTC precious metals! I can't speak for others but personally very interested in leveraging the BTC price to buy physical Silver when the ratio is good. Maybe you could consider something like this..

Investors/Speculators buy contracts denominated in BTC, you hold the BTC in guaranteed interest earning deposits that you compound and build up. You maintain liquidity so you can withdraw the BTC whenever you need to buy physical metal. For example: I could guarantee you BTC liquidity at short notice with the SILVER, GOLD, PLATINUM or RAREEARTH assets on GLBSE. My metals assets would earn you at least 3.52% a month before compounding the weekly interest. BTC lenders will pay you 1% a week or more at the moment for BTC deposits that you could have on call also. The BTC investments your asset has could sit in escrow accounts which may add more confidence for your investors.

Assuming the BTC price goes through spikes (just assuming) the cost of ounces and kilos could start looking pretty attractive for anyone who has committed BTC while it is low. Working out the prices you quote may be tricky. Maybe contracts could be filled early if the price is met.. 1 BTC to 1 Troy Oz of Ag within 12 months  You never know! Interesting to see what you come up with. If I can help provide any part of the liquidity you may need let me know.
