If it goes below 200 on all the exchanges, I think we are looking at the next big step down to 100-150. We haven't had a big step down since Jan-Feb, when it went from 330 down to 200. Since then it has been mainly in the 200-300 range.
The lesson from last year is that the big steps down occur when the price goes below the previous low, which in the current case is 200. When the price goes below the previous low, many people panic sell, thinking the end is nigh, and hence the next big step down occurs. The price never really recovers afterwards.
See, for example, the recent high of 320ish. It was still below the previous step level, which was north of 330 (in Dec 2014).
So my prediction is that in the next few days it will go below 200, and then, very rapidly (ie before the end of this month), the next big step down will occur, to USD 100-150 range. There will be much wailing and gnashing of teeth.
