If u made daily purchases of bitcoin from 2010, you'd average a 400% compounded, annualized return. You could purchase any amount, and that would be your average compound return, as long as you invested the same amount each day.
This is an incredible figure. It is compounded and annualized, so it is the most "telling" form of return. Compare this with base government bond yields (0-2% per year compounded), base government overnight yields (sometimes negative returns!), and you will start to see how powerful this % compound annual return is.
