Here is my interpretation of the "Best Time To Buy" Bitcoin over its lifetime using a logarithmic regression trendline. The upper and lower lines are 10% deviations from the centre line. I calculated the trendline in excel and then coded my results into pine script.
This indi shows the bottoms of market. It depends on average price and rate of change in daily. If you see in red on chart this means you shold buy :)
It works only on daily period.
Use your own risk.
Cheers
