Overview
Bitcoin Logarithmic Growth Curves computes upper and lower growth curves based on historical time elapsed since July 2010, deriving logarithmic deviation channels scaled back to linear price values. Inputs allow users to adjust top and bottom intercept and slope values, toggle intermediate Fibonacci lines, enable curve projections, and switch between dark and light visual themes.
- Logarithmic growth channel curves
- Fibonacci channel retracement levels
- Customizable slope and intercept parameters
- Dark and light theme options
