Review Questions

• How does the decentralized nature of cryptocurrency impact its usability compared to traditional currencies?
  • The decentralized nature of cryptocurrency allows for direct transactions between users without needing intermediaries like banks. This leads to faster transaction times and lower fees compared to traditional banking systems. Additionally, this structure enhances privacy and security for users, as their transactions are recorded on a public ledger rather than being tied to a specific financial institution.
• Analyze the role of blockchain technology in ensuring the security and integrity of cryptocurrency transactions.
  • Blockchain technology plays a crucial role in securing cryptocurrency transactions by providing a transparent and tamper-proof ledger. Each transaction is recorded in blocks that are linked together in chronological order, making it nearly impossible to alter any information without consensus from the network participants. This enhances trust among users and mitigates risks associated with fraud and double-spending.
• Evaluate the potential risks and benefits of using cryptocurrencies in the context of global financial systems and economies.
  • Using cryptocurrencies presents both risks and benefits for global financial systems. On one hand, they offer greater financial inclusion and lower transaction costs, especially in regions with limited banking access. On the other hand, their volatility poses risks for investors and could lead to financial instability if not properly regulated. Additionally, issues like money laundering and cybercrime could arise if cryptocurrencies become widely adopted without adequate oversight.
