You Cant Trade Steem On Bittrex

Currently its appears that trading Steem on the Exchanges does not work Its been like this for over a week. I am not sure why this is so. It would in view give artificial price support to Steem as people can not sell the product. I don't know why the exchange have blocked the rading of it.

It appears the past week I personally could not bring steem across to the exchange not sure why this is?
