Like I said, Steem has problems on the market places. They didn't offer Steem for a while and it s all strange and confusing what is going on there. Needs technical improvement in Bittrex and Poloniex. Then there are big users selling Steem by powering down. Whenever that happens it is quite a bit of Steem and the price drops since there is not sooo much trading with Steem going on right now. And then there is Shapeshift.io that service that changes one currency into another. It used to support Steem but recently took it off for unknow reasons. Many things coming together. But don't worry, the price will go up as soon as the new updates for Steemit are coming with the new UX/UI and then there will be a multi million Dollar marketing campaign as well.
