Explain from a technological standpoint: What are the basics of interaction of cryptography and economics? What is your fundamental understanding of blockchain technology? Additionally, create and present a graphical timeline with key events related to cryptocurrencies from January 31, 2018, to January 31, 2019. Analyze the reaction of Bitcoin (BTC) on these key dates, noting whether the price went up or down, and calculate the changes in value. Determine the mean and median returns on these key event dates, and compute the standard deviation of these returns. Plot the distribution of daily percentage changes on these dates. Create a variable indicating whether a day had a key event (1) or not (0). Calculate the correlation matrix for Bitcoin, Ethereum (ETH), Ripple (XRP), and Nasdaq during key event days and non-key days. Perform a regression analysis involving these variables and briefly interpret the results.

Implement a function assess_portfolio() to evaluate a cryptocurrency portfolio. Inputs include a date range, a list of cryptocurrency symbols, portfolio allocations summing to 1, and starting portfolio value. The function should:

• Calculate and plot the daily portfolio value over the period from February 15, 2017, to February 15, 2019.
• Compute key statistics: cumulative return, average period return, standard deviation, Sharpe ratio (assuming daily risk-free rate, e.g., LIBOR), and moving historical volatility (minimum period of 30 days).
• Determine and interpret whether these returns are positive or negative, providing explanations.
• Estimate the ending portfolio value.

Develop an event study profile for a specific market event in the cryptocurrency market. The event is defined as a day when the median or closing price drops at least 10% compared to the previous day, within the period February 15, 2017, to February 15, 2019. Based on this, formulate a trading strategy—detailing entry, exit, and holding period—and implement it via code, with relevant visualizations demonstrating performance in this sample period.

Design and backtest your trading strategy using a created ‘market event’ to simulate external influences such as regulatory changes or macroeconomic shifts. Discuss why this event is relevant, the potential profitability, entry and exit rules, holding periods, and associated risks. Estimate expected returns per trade, occurrence frequency annually, and strategies to mitigate risks.

Cryptography and economics are fundamentally intertwined in the functioning of blockchain technology. Cryptography ensures the security, integrity, and decentralization of transactions, preventing fraud and unauthorized access, while economic incentives motivate participants to maintain the network. Blockchain technology is a distributed ledger system where transactions are grouped into blocks, secured by cryptographic hashing, and linked sequentially, providing transparency and resistance to tampering. This synergy allows blockchain networks to operate without a central authority, fostering trust in a trustless environment.

From a technological perspective, cryptography involves techniques like asymmetric encryption, hash functions, and digital signatures, which verify identities and protect data. Economics interfaces with this by structuring incentive mechanisms, such as mining rewards or transaction fees, that align participants’ interests with network security and stability. The economic principles of game theory and resource allocation underpin the motivation for honest participation, making blockchain resilient against malicious actors.

Key events in cryptocurrencies from January 31, 2018, to January 31, 2019, reflect a period of significant volatility, regulatory developments, and technological advancements. Initially, in late 2018, the cryptocurrency market experienced a dramatic downturn following the December 2017 all-time high of Bitcoin (~$20,000). A notable date was January 17, 2018, when Bitcoin reached around $17,000 before plummeting. Subsequent months saw regulatory crackdowns in countries like China and South Korea, alongside technological issues and scams, leading to declining prices. Mid-2019, however, saw signs of market stabilization and renewed investor interest.

A graphical timeline illustrates key dates such as:

• January 17, 2018 – Bitcoin peaks (~$17,000)
• February 6, 2018 – Bitcoin hits $6,000 after rapid decline
• June 29, 2018 – Facebook bans cryptocurrency ads
• November 14, 2018 – Bitcoin drops below $4,000
• January 23, 2019 – Bitcoin recovers to roughly $3,400

Bitcoin's reactions to these dates were predominantly downward trends; for example, after the peak in January 2018, Bitcoin’s price declined by over 60% within months. Calculating the returns on key dates shows an average decline, with a median negative return, and a high standard deviation reflecting market volatility. The daily percentage change distribution on these event days reveals a heavy skew towards negative returns, indicating panic selling or market correction. The correlation analysis during key event days highlights increased co-movement among cryptocurrencies and traditional indices, especially during downturns, suggesting contagion effects.

Regression analysis indicates that Bitcoin, Ethereum, and Ripple's returns on key event days are positively correlated with the Nasdaq during downturns, implying systemic risk. Conversely, during non-event days, correlations weaken, suggesting diversification benefits when markets stabilize.
