I think your premise is that the "variance" is constant or of constant range no matter what the value of the coin.
I wonder (without any statistical analysis) whether coin go up and down more in a numerical range and not a % range.?
Having said that the BTC which is slow to move still swings so wildly both in range and acceleration (slant of the line on the graph) - who knows? Lol
Very interesting though ty...im new to the idea of graph analysis with investment in mind...there seem quite a few interesting concepts eg when the 50day moving average crosses the 200 day, etc etc
Many thanks.
