Q. Price volatility of cryptocurrencies is high most likely because they are:

选项：

A.subject to self-imposed limit on supply.

B.correlated with traditional risky asset classes.

C.highly speculative with no fundamental value or cash flow.

解释：

The correct answer is C. Cryptocurrencies are purely speculative, with no fundamental value or future cash flow. There is no consensus on how to value them. Their markets are therefore subject to rapid price swings, changes, and uncertainty. But historically, their performance has relatively low correlations with traditional asset classes.
