Digital assets differ from traditional financial securities in that

选项：

A.

digital assets are subject to a broader legal protection framework.

B.

digital assets are not valued based on their expected future cash flow.

C.

transaction records of digital assets require a centralized intermediary.

解释：

The correct answer is B. Most digital assets do not have a fundamental value based on underlying assets or on the potential cash flow or earnings they are expected to generate. To date, the legal and regulatory frameworks for digital assets are still evolving, and there is generally less legal protection compared to traditional financial securities. Digital asset transactions are recorded on a distributed ledger, and no centralized intermediary is required in the process.
