The Momentum Loop: How Bitcoin Rallies Drive New Investor Demand

A new working paper from the Federal Reserve Bank of Cleveland provides rare experimental evidence of the "momentum effect" within the cryptocurrency market. The study, titled Do You Even Crypto, Bro?, suggests that Bitcoin’s price gains do more than just enrich existing holders—they actively recruit new participants by inflating expectations of future returns. By providing potential investors with data on past performance, researchers observed a significant shift in both sentiment and actual ownership, highlighting a psychological feedback loop that often characterizes speculative markets.

From Information to Ownership

The researchers conducted a controlled experiment where participants were shown various pieces of financial information, including Bitcoin’s 12-month performance. Those exposed to Bitcoin’s positive returns became notably more bullish, raising their expected future returns by over 3 percentage points compared to a control group. This shift in mindset translated into real-world action; participants shown Bitcoin’s growth were approximately 2.5 percentage points more likely to own the asset in subsequent surveys. Most of this new capital was diverted from traditional cash reserves, such as checking and savings accounts, rather than from other investment vehicles, indicating that crypto rallies specifically pull money out of low-yield liquid assets.

Knowledge Gaps and the Wealth Effect

The study found that Bitcoin’s price rallies have the strongest pull on individuals with limited knowledge of the asset class. While demographic factors like age and income play a role in who owns crypto, the most powerful predictors of ownership are the investor’s personal beliefs regarding risk and reward. Furthermore, the research identified a distinct "wealth effect" among existing holders: Bitcoin profits are typically treated like a temporary windfall rather than a permanent increase in income. This leads to a spike in one-time purchases of durable goods, such as electronics or appliances, while daily spending on routine expenses remains largely unchanged. Ultimately, the research suggests that by extrapolating past gains into the future, new and often less-informed investors create a demand surge that can contribute to the formation of asset-price bubbles.
