Question. Using daily close data, please plot the following two exchange rates in the same chart: i) Exchange rate between VEF (Venezuelan Bolivar) and USD from 1 July 2013 and 1 July 2018; and ii) Exchange rate between Bitcoin (BTC) and USD from 1 July 2013 and 1 July 2018; Indicate one specific point on each of these two lines where the trend changes, and provide some reason(s) why this is the case. (Hint: Please clearly mark the legend and the relevant information on the axes, and provide data sources. You can use the left axis for the VEF/USD exchange rate, while using the right axis for the BTC/USD exchange rate. Please note that you should create a chart on your own rather than copying from other sources.).

Based on the data you collected for VEF/USD, and Bitcoin/USD between 1 July 2013 and 1 July 2018, please calculate the volatility of each currency pair and comment on which currency pair is more volatile?
