Eth- Continues to follow a strangely accurate fractal

Aug 20th I suggested that Eth would enter a sideways channel. That is now confirmed. How could I have know that without a crystal ball?
Fractals are a mathematical anomaly. Price action "respects" these "trendlines" & patterns so perfecly. Yet on a graph (chart), this linear function has several veriables (y=mx+b). With this may variables in a linear equation, how do you explain fractals?
- Is human behavior just simply predictably repeating?
