Don't put too much stock into the connection between the real-world price and the bts-silver price at this point in time. This is the early innings. At the moment the bts-silver has little attention so it is not an effective comparison. This project will generate more interest and more trading activity.

The long term goal is to have bts-silver trading volume more active than the off-chain centralized paper markets. Then I would expect the exchange ratios to track more tightly.
