Bitcoin does not have a compound annual growth rate CAGR. It has an annual rate of return ARR. At it’s core CAGR is a way to describe in one number what happens when you reinvest an interest payment or dividend back into the original principle over many years at different interest rates. Bitcoin does not pay interest so you cannot use the CAGR maths from the fiat investment system to evaluate a return. Bitcoin is a completely different beast.
