Question 2

• Option A: Traditional financial systems aren't fully anonymous (e.g., bank accounts are linked to identities), while many cryptocurrencies offer pseudonymity, so A is wrong.
• Option B: Traditional financial systems (like banks) are centralized (controlled by institutions), and many cryptocurrencies are decentralized (operate on peer - to - peer networks), so B matches the primary difference.
• Option C: Traditional money is issued by governments, and most cryptocurrencies aren't issued by governments, so C is reversed and wrong.
• Option D: Cryptocurrencies often use blockchain, and traditional systems don't, so D is wrong.

• Option A: Centralized banking software is for traditional centralized finance, not decentralized digital currencies, so A is wrong.
• Option B: Blockchain is the underlying technology for most decentralized digital currencies (like Bitcoin, Ethereum), as it enables distributed, transparent, and secure ledgers without a central authority, so B is correct.
• Option C: Credit card networks are centralized and for traditional payment systems, not for decentralized digital currencies, so C is wrong.
• Option D: Secure email protocols are for email security, not related to decentralized digital currencies, so D is wrong.

Answer:

B. Traditional systems are centralized; many cryptocurrencies are decentralized
