Also it should be noted that bitusd is currently trading at about 1.08 usd/bitusd.

This means that the demand for bitusd is greater than the supply. People are paying about 8% more for a bitusd than is guaranteed by the price feed.

Borrowing bitusd now, and then selling it for another crypto will likely provide an opportunity to pay back the debt at several percentage points less then the current prices!

The network needs more bitusd and is providing an incentive for bitshares holders to create more!
