Bitcoin as a Speculative Asset
Bitcoin’s extreme volatility makes it a high-risk, high-reward speculation rather than a traditional investment. Past performance includes both meteoric rises and sharp declines. Always conduct independent research before investing.
FAQs

A: CPI-U adjustments use interpolation/extrapolation for dates between or beyond official readings.
Q: Why do Bitcoin prices differ across exchanges?  
A: Decentralized trading leads to price variations due to liquidity and regional demand.
Q: Is Bitcoin a safe long-term investment?
