Careful with using the order book to assess demand, I could put in an order for a few bitcoins at the lowest price value (1 satoshi or something) and all of a sudden the steem on the orderbook would shoot up and look like there's huge demand, if you only look at the amount of Steem.
I think it's better to look at the bitcoin numbers on bittrex, and the volume going through. Volume mainly, whihc is multiples higher than it was pre 4th july.
