Bitcoin in Retirement Portfolios: 1% Allocation Boosts Returns, Fidelity Report Says

Bitcoin has been the top-performing asset class in 11 of the past 15 years, according to a report from Yahoo Finance. However, since reaching its all-time high in October 2025, the cryptocurrency has declined by 39%.

For individuals planning for retirement several decades away, analysts have examined whether Bitcoin deserves a place in a long-term savings portfolio. The asset is considered a scarce store of value, with its steadily decreasing new supply from mining expected to support its price over extended periods.

Fidelity Digital Assets published a report earlier this year that found moving from a zero percent Bitcoin allocation to even a small one can be among the most beneficial portfolio adjustments an investor can make. The report, which aligns with earlier Fidelity research, indicated that the largest improvement in risk-adjusted returns comes from allocating the first 1% of a portfolio's total value to Bitcoin. For a portfolio previously diversified with a standard 60/40 mix of stocks and bonds, adding that small Bitcoin allocation boosted annual returns by approximately 2%, while increasing the portfolio's maximum drawdown by only about 0.5%.

Bitcoin's risk does not scale linearly with allocation but accelerates. According to the Fidelity report, replacing 1% of a 60/40 portfolio with Bitcoin contributed roughly 2.7% of total portfolio volatility, whereas a 5% allocation contributed 17.8%. Investors are advised to keep Bitcoin between 1% and 5% of their total portfolio, leaning toward the lower end if they are within a decade of retiring. A longer investment horizon provides more time to recover from the 40% to 80% drawdowns that Bitcoin has experienced in every one of its halving cycles.
