In the 2017 cycle, Bitcoin spent a prolonged period consolidating below this line before finally pushing through it. Once that breakout occurred, the price entered into a strong rally phase that lasted one year. The move ultimately carried BTC from below $1,000 to almost $20,000 in a relatively compressed timeframe.
On the other hand, the 2021 cycle showed a different behavior. Bitcoin’s price action moved more faster earlier in the structure, breaking above trend resistance sooner and running into its $69,000 peak without the same extended base formation seen in 2017.
The red support trendline on the chart has repeatedly acted as a floor during pullbacks across several cycles. Whenever Bitcoin has tested or moved close to this area, it has coincided with periods that later proved to be significant accumulation phases.
