Bitcoin returned 150% in 2023. The S&P 500 returned 26%. But Bitcoin also fell 65% in 2022, while the S&P 500 fell 19%. The comparison isn't as simple as looking at one year's returns. Here's a rigorous analysis of crypto vs stocks across the dimensions that matter.

Volatility: Crypto is categorically more volatile

Bitcoin's annualised volatility is typically 60–100%, compared to 15–20% for the S&P 500. This means crypto prices move 3–5x more dramatically than stocks in both directions. For long-term investors who can tolerate volatility and have a multi-decade time horizon, this volatility can be compensated by higher returns. For investors who might need to sell in the next 5 years, this volatility can be catastrophic.

Returns: The complicated truth

Bitcoin has outperformed the S&P 500 on a 10-year basis, but the comparison requires enormous survivorship bias — picking Bitcoin as the winning crypto from thousands of options in hindsight. Most altcoins from 2013 no longer exist or are worth a fraction of their peak. Individual stock-picking similarly suffers from survivorship bias. When comparing index-level returns (all stocks vs all crypto), the picture is less clear.

Fundamental differences

Stocks represent ownership in businesses with revenues, profits, employees, products, and assets. Even in a severe market downturn, established companies continue to generate cash flows. Cryptocurrency is a medium of exchange, a store of value, or a platform for decentralised applications. Its value is based on adoption, network effects, and market sentiment — not earnings.

This means stocks have a 'floor' anchored in business value. Crypto has no such anchor — its value can fall to zero in extreme scenarios.

Role in a portfolio

Most financial advisers suggest treating crypto as a high-risk satellite allocation of 0–15% of a portfolio, not as a substitute for equities. The core of a long-term portfolio should be globally diversified stocks (via ETFs), with crypto as a speculative addition for those who understand and accept the additional volatility.

Frequently Asked Questions

Should I invest in crypto or stocks? +
For most investors, a globally diversified stock ETF should form the core of their portfolio. Crypto can be added as a small speculative allocation (5–15%) for those who understand the risks and can tolerate high volatility.
Can crypto replace stocks in a portfolio? +
We wouldn't recommend it. Crypto lacks the fundamental earnings anchor of stocks, is subject to higher regulatory risk, and has produced devastating multi-year drawdowns. Stocks and crypto serve different portfolio roles.
