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.

Instead of simply holding Bitcoin, MicroStrategy layered on complex debt instruments like preferred stock. This convolution made it difficult for investors to understand the true risk and preference stack, contributing to the stock trading at a discount to its own assets when sentiment turned. Simplicity is safer.

Today's market is more fragile than during the dot-com bubble because value is even more concentrated in a few tech giants. Ten companies now represent 40% of the S&P 500. This hyper-concentration means the failure of a single company or trend (like AI) doesn't just impact a sector; it threatens the entire global economy, removing all robustness from the system.

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.

Conventional definitions of risk, like volatility, are flawed. True risk is an event you did not anticipate that forces you to abandon your strategy at a bad time. Foreseeable events, like a 50% market crash, are not risks but rather expected parts of the market cycle that a robust strategy should be built to withstand.

The global economy's dependence on AI has created a massive concentration of risk in NVIDIA. Its valuation, exceeding the entire German stock market, makes it a single point of failure. A significant drop in its stock—which could still leave it overvalued—would have catastrophic ripple effects with nowhere for capital to hide.

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.

The surprising correlation between the McDonald's McRib being on the menu and higher returns in both the S&P 500 and Bitcoin demonstrates how unconventional, even humorous, cultural events can function as market signals. This highlights the narrative-driven and sometimes irrational nature of financial markets and investor sentiment.
