As a highly volatile and retail-driven asset, Bitcoin serves as a leading indicator for investor risk appetite. It's a "canary in the coal mine" where a "risk on" sentiment leads to sharp increases, while a "risk off" mood triggers rapid declines, often preceding moves in traditional markets.

Phenomena like bank runs or speculative bubbles are often rational responses to perceived common knowledge. People act not on an asset's fundamental value, but on their prediction of how others will act, who are in turn predicting others' actions. This creates self-fulfilling prophecies.

The current AI boom isn't just another tech bubble; it's a "bubble with bigger variance." The potential for massive upswings is matched by the risk of equally significant downswings. Investors and founders must have an unusually high tolerance for risk and volatility to succeed.

Current AI investment patterns mirror the "round-tripping" seen in the late '90s tech bubble. For example, NVIDIA invests billions in a startup like OpenAI, which then uses that capital to purchase NVIDIA chips. This creates an illusion of demand and inflated valuations, masking the lack of real, external customer revenue.

Widespread public debate about whether a market is in a bubble is evidence that it is not. A true financial bubble requires capitulation, where nearly everyone believes the high valuations are justified and the skepticism disappears. As long as there are many vocal doubters, the market has not reached the euphoric peak that precedes a crash.

Innovation doesn't happen without risk-taking. What we call speculation is the essential fuel that allows groundbreaking ideas, like those of Elon Musk, to get funded and developed. While dangerous, attempting to eliminate speculative bubbles entirely would also stifle world-changing progress.

Bitcoin's 27% plunge, far exceeding the stock market's dip, shows how high-beta assets react disproportionately to macro uncertainty. When the central bank signals a slowdown due to a "foggy" outlook, investors flee to safety, punishing the riskiest assets the most.

The dramatic rise in BNPL usage across all demographics, including 41% of young shoppers, is a negative forward-looking indicator. While framed as innovation, it's a form of modern usury that reveals consumers cannot afford their purchases, creating a significant, under-discussed credit risk for the economy.

Contrary to intuition, widespread fear and discussion of a market bubble often precede a final, insane surge upward. The real crash tends to happen later, when the consensus shifts to believing in a 'new economic model.' This highlights a key psychological dynamic of market cycles where peak anxiety doesn't signal an immediate top.
