You spot the triangle right (or haejin was first) but what trigger a breakthrough through the resistance line is hidden inside a triangle. this is a harmonic pattern ABCD indicating that price move will follow. Check my analysis here #1. I start a serious of Steem price predictions, because we are Steemians.

One more remark. Support line in this triangle is very weak. It's defined with just two price dips far apart. More dips or picks define a line stronger it become. In my analysis I even not draw support line of a triangle.
