Explanation:
According to a different source, these are the options that are missing from this question:
A. “It first appeared in 2009.”
B. “In mid-2018, one bitcoin was worth $6,100.”
C. “They are just the latest development in the long history of money.”
D. “Bitcoin is the most widely used cryptocurrency today.”
In the text, the author describes the way Bitcoin has grown and developed throughout the last ten years. Although the rise of Bitcoin suggests that the currency is extremely successful and popular, the author also tells us that Bitcoin is in reality the last example of a long list of developments in the history of money. When we analyze it in this way, we can assume that Bitcoin might not be as significant as we might be inclined to believe initially. This can lead us to believe that Bitcoin is unlikely to be a form of currency used by young people any time soon.
