At this point, in order to reach $15k, we have to break above resistance in the $5400 to $6400 arena, which might not be too difficult, and we would have to break above resistance in the $8500 to $12500 arena, which would be a bit more difficult, but not impossible.... so $15k is possible in this price run and in this calendar year or soon thereafter. I would say less than a 20% chance within the upcoming year, and probably less than a 15% chance this calendar year.
Of course, if prices break above the price points that I just mentioned, then the odds of reaching $15k become better, and if any price correction is larger or sustained, then the odds of reaching $15k in this price run up become lower.
