Review Questions

• How does cryptocurrency utilize blockchain technology to facilitate secure transactions?
  • Cryptocurrency relies on blockchain technology to create a decentralized ledger where all transactions are recorded in a secure and transparent manner. Each transaction is grouped into blocks that are linked together chronologically, creating a chain that cannot be altered without consensus from the network. This process ensures that transactions are verified by multiple participants (nodes) before being added to the ledger, providing security against fraud and double-spending.
• What are the implications of decentralized financial systems enabled by cryptocurrencies for traditional banking institutions?
  • The rise of cryptocurrencies introduces significant challenges for traditional banking institutions by allowing consumers to engage in peer-to-peer transactions without intermediaries. This shift threatens the established banking model, as customers may prefer lower fees and faster transaction times offered by cryptocurrencies. Additionally, banks must adapt to the competitive landscape created by digital currencies, potentially leading to innovations in their own services to remain relevant in a changing financial environment.
• Evaluate the potential risks associated with cryptocurrency investments and how they compare to traditional asset classes.
  • Investing in cryptocurrencies carries unique risks such as high volatility, lack of regulation, and potential for fraud or hacking. Unlike traditional asset classes that may have historical data supporting valuation trends, cryptocurrencies can experience rapid price fluctuations driven by speculation. Furthermore, the absence of investor protection mechanisms found in conventional markets increases the vulnerability of investors. Evaluating these risks is essential for informed decision-making when considering cryptocurrency as part of an investment portfolio.
