To put it into another perspective:
Cost to buy 3 FeeShares: 0.3363 BTC
To break even on that investment, the Exchange would need to make 33,630 BTC in profit, or $15,000,000 USD.

This doesn't seem realistic to me. The coin's value would need to drop significantly for the FeeShare purchases and then rise significantly for this to be a realistic investment. That's also assuming the exchange grows to become a major player in the cryptocurrency trading market.. and I mean MAJOR.
