Bitcoin vs Stocks for Retirement
Under the Power Law model, a 100% Bitcoin portfolio would be 15.7× larger than a traditional 60/40 allocation by age 51. However, this comes with significantly higher volatility and concentration risk.
Your diversified mix (stocks, bonds, and Bitcoin) offers a middle ground — capturing some of Bitcoin's upside while maintaining exposure to traditional assets. At $4.1M, it outperforms the traditional 60/40 ($1.2M) while being less volatile than a pure Bitcoin portfolio.
The decade-by-decade table shows how these strategies diverge over time. In early years, the differences are modest. But compounding over 21 years creates dramatic separation, especially for Bitcoin-heavy allocations.
This is not financial advice. Actual returns will vary. Bitcoin is highly volatile.
