0 - top 1 - bottom If we already had bottomed as wave C, then this relationship can be applied to estimate the timing for next bull run.

I used fib on time scale to measure the cycle and to tear up the fractal into different stages of the market. These proportions most likely can be applied to the case happened in recent 2 years.

Bitcoin history pattern relativity to current case through fib spiral
Real bullrun will start whenever price enters green zone
Mind the long-term demand zone which is based on support parallel trendlines dragged from lowest points with its specific angle. I'd long whenever price falls inside green area or breaks out above triangular formation.
