It's just strange that not all exchanges are at the same price yet. They are off quite a bit. One says $890 another says $880 and yobit had it at $986 but since yesterday I could not even get to that site anymore. 
Do you talk about YoBit when you say that you will not go to that site anymore? YoBit is a good site for my taste. They always have the highest prices for bitcoin that give me to cash out my coins with the highest profit.
