> i'm just saying, that because bitcoin's supply is power of 2, a log2 chart is the right one to use
I’m just saying that there’s no difference, from a charting perspective because their shapes are identical, merely scaled.
If you take a log10 chart, then fit it so that the min and max are at the bottom and top of the rendered height, then do the same for a log2 chart, the two charts will be literally identical, with the only exception being the labels on the y-axis.
Algebraically, using a different log base results in a linear scaling factor on the output. Plotting to pixels requires its own linear scaling factor. And so a log chart will look the same regardless of the base, provided the pixel scaling factor is adjusted accordingly.
