1. At the end of June 2010, one Bitcoin could be purchased for $0.0008 (yes, this is 8/100 of a cent). Towards the end of June 2022, one Bitcoin was worth $21,000.

1. If you invested in one Bitcoin in June 2010 at $0.0008 and sold in June 2022 (12 years later) at $21,000, what would your compound annual rate of return been?

2. At the end of June 2016, one Bitcoin was worth $674. What would your compound annual rate of return have been if you invested in June 2016 at $674 and sold in June 2022 (six years later) at $21,000?

3. Lastly, assume you invested in one Bitcoin at its peak at the end of October 2021 at $67,554 (it was actually very early November, but I changed it to the end of October to make the calculation simple). Had you sold it in June 2022 for $21,000, what would your compound annual return have been? (For this last calculation, the time-period is 8 months, so N=8/12).
