In the context of the debate, what specific evidentiary requirement is allegedly placed on sellers if Bitcoin maintains an $83,000 price level through December 2026?

En savoir plus sur ce sujet

• A.Sellers must provide compelling fundamental justification for why the asset is overvalued despite sustained market consensus at that price.
• B.Sellers are legally required to disclose their short positions to regulatory bodies before executing trades.
• C.Buyers must continuously demonstrate that the $83,000 price is supported by the underlying network hash rate.
• D.Sellers must calculate the capital gains tax implications of their trades prior to execution.

Which logical fallacy does the counter-thesis argue is committed when a future projected $83,000 Bitcoin price is treated as an already established empirical benchmark?

En savoir plus sur ce sujet

• A.The sunk cost fallacy, because traders are holding onto losing positions hoping the price will eventually reach $83,000.
• B.Begging the question by assuming a future speculative event as a present factual premise to validate a current argument.
• C.The historian's fallacy, which assumes past market participants had the same information as current traders.
• D.The base rate fallacy, where traders ignore the historical average returns of cryptocurrencies in favor of specific price targets.

Which continuous-time stochastic process is typically utilized in Monte Carlo simulations to model asset prices assuming constant drift and volatility?

En savoir plus sur ce sujet

• A.The Fibonacci retracement sequence, which mathematically predicts exact future price levels based on historical volatility.
• B.Arithmetic Brownian Motion, which models absolute price changes and allows for negative asset prices.
• C.Geometric Brownian Motion, because it ensures prices remain strictly positive while modeling logarithmic returns as normally distributed.
• D.The Black-Scholes options pricing formula, which calculates the theoretical value of derivatives at expiration.

Under the Random Walk Hypothesis (Fama 1965), which specific statistical property of the error terms ensures that past price movements cannot predict future asset prices?

En savoir plus sur ce sujet

• A.The error terms perfectly correlate with overall market sentiment, making individual asset predictions impossible.
• B.The error terms exhibit strong positive autocorrelation, meaning past trends continue indefinitely.
• C.The error terms are adjusted for inflation using the Consumer Price Index to reflect real purchasing power.
• D.The error terms are independently and identically distributed (i.i.d.) with an expected value of zero.

In Kyle's Model of Market Microstructure (Kyle 1985), how do noise traders mechanically contribute to the market equilibrium alongside informed traders and risk-neutral market makers?

En savoir plus sur ce sujet

• A.They provide random, uninformed liquidity that camouflages the trades of informed traders, preventing market makers from immediately deducing the true asset value.
• B.They consistently lose money to market makers because they trade based on technical analysis rather than fundamental news.
• C.They eliminate information asymmetry by rapidly broadcasting their trades, making the market perfectly efficient.
• D.They increase the total daily trading volume, which allows the exchange to collect higher transaction fees.

Which strict foundational axiom must be satisfied for economic actors' underlying preferences to be validly deduced from their observed purchasing choices under Revealed Preference Theory (Samuelson 1938)?

En savoir plus sur ce sujet

• A.The assumption of perfect information, meaning consumers must know the exact future utility of every product before buying.
• B.The Weak Axiom of Revealed Preference (WARP), which dictates that if bundle X is chosen over an affordable bundle Y, bundle Y cannot be chosen over X when both are affordable.
• C.The assumption of bounded rationality, which states consumers make satisfactory rather than optimal choices due to cognitive limits.
• D.The Law of Diminishing Marginal Utility, which ensures that each additional unit consumed provides less satisfaction.

Assuming the Semi-Strong EMH holds, how would an unanticipated hawkish pivot in the current Federal Reserve interest rate cycle theoretically adjust Bitcoin's $83,000 equilibrium price?

En savoir plus sur ce sujet

• A.The price would slowly decline over several weeks as retail investors gradually read the news and sell their holdings.
• B.The price would remain completely unchanged because Bitcoin is a decentralized asset immune to traditional macroeconomic policies.
• C.The price would instantaneously adjust downward to a new equilibrium as the market immediately prices in the higher opportunity cost of holding non-yielding assets.
• D.The price would fluctuate wildly until the Federal Reserve publishes its annual budget report.

Using Kyle's Lambda, how would sudden regulatory ambiguity regarding stablecoin taxation likely impact the price adjustment required to absorb one unit of Bitcoin order flow?

• A.Kyle's Lambda would decrease because regulatory news always causes trading volume to spike, making it cheaper to execute large orders.
• B.Kyle's Lambda would decrease, indicating that market makers are more willing to absorb order flow due to the predictability of tax regulations.
• C.Kyle's Lambda would remain static because stablecoin taxation only affects off-chain fiat conversions, not on-chain order flow.
• D.Kyle's Lambda would increase, meaning a larger price adjustment is required per unit of order flow because market makers face higher adverse selection risk and reduced liquidity.

How does the core assumption regarding price increments in the Random Walk Hypothesis (Fama 1965) conflict with the fundamental mechanism of price discovery in Kyle's Model of Market Microstructure (Kyle 1985)?

En savoir plus sur ce sujet

• A.The Random Walk Hypothesis assumes price changes are independent and unforecastable, whereas Kyle's Model demonstrates that prices systematically adjust based on the information content extracted from order flow.
• B.The Random Walk Hypothesis proves that markets are rigged by institutional players, while Kyle's Model assumes all retail traders have equal access to information.
• C.The Random Walk Hypothesis argues that prices adjust deterministically to fundamental news, whereas Kyle's Model claims prices move purely due to random noise trading.
• D.The Random Walk Hypothesis relies on high-frequency trading algorithms, whereas Kyle's Model was designed exclusively for manual open-outcry trading pits.
