Problem
Look at the graphs for Bitcoin-to-US-dollar exchange rates (number of dollars for every one Bitcoin) and the Consumer Price Index (CPI) from January 2015 to the present day. Compare the two charts, and consider price and index fluctuations over time. Compared to holding on to US dollars, do you think buying Bitcoins with US dollars is a risky investment, an opportunity, or both? Use the data from the graphs to quantify your answer. Additionally, can you think of alternatives to holding on to one's money or investing in Bitcoin that's both less risky than Bitcoin but won't lose as much value as holding on to the dollar?
