US-based financial management company Bitwise Asset Management has published a new study evaluating the impact of adding Bitcoin to traditional investment portfolios on performance. In the research using Bloomberg data, the returns of holding 2.5 percent of Bitcoin in portfolios in the 12-year period from 2014 to the end of 2025 were examined. In the analysis, the effects of adding Bitcoin to a traditional 60 percent stock and 40 percent bond portfolio on the return and risk profile were discussed.
Return and Sharpe Ratio Increase in Portfolio Added to Bitcoin
The Bitwise report showed that when a low percentage of Bitcoin was added to portfolios, total returns increased over all three-year investment periods. According to the table in the research, while an increase was achieved in 75.58 percent of the returns in one-year holding periods, this rate increased to 93.81 percent in the two-year period. In all three-year periods, the portfolio return was higher than the traditional model and there was no loss during these periods.
In addition, the Sharpe ratio, which is considered a risk-return indicator, has also improved significantly. While the Sharpe ratio increased by 79.57 percent in the one-year term, an increase of 97.95 percent was recorded in the two-year periods. In all three-year periods, the Sharpe ratio progressed at a positive level and the minimum change was noted to be positive.
Data Set and Market Periods
The study included Bitcoin’s performance over different market cycles. In the research, the 2014-2015 bear market, the 2017-2018 big pullback, the COVID-19 crash, the 2021 bull run, the sharp decline in 2022, the 2023-2024 recovery process, the 2024-2025 rise and current price corrections were taken into account.
During these periods, it was observed that the strategy of holding a portfolio for three years or more maintained its advantages in terms of risk and return. Even the years when Bitcoin fluctuated heavily or experienced sharp declines did not change the general picture.
Periodic Balancing Method in Portfolio Management
The methodological element that stood out in the analysis was the rebalancing of the weight in the Bitcoin portfolio every quarter. Thus, excessive growth of the Bitcoin share was prevented in times of rise, and balance was maintained through purchases in times of decline. This systematic approach both limited risks and helped protect the portfolio from excessive volatility.
The report revealed that Bitcoin-heavy portfolios contribute to the risk-return balance even in short-term periods, and that this contribution is permanent and high, especially in the three-year or longer term.
In addition, it was stated that the lowest change in the risk index in two-year periods was recorded as almost zero and the return-to-risk profile did not worsen significantly in any two-year interval.
Reflections for Financial Advisors
It was emphasized that this report by Bitwise is also a guide for financial advisors who are considering holding cryptocurrencies in their portfolios. It was stated that all three-year loss-free periods and positive risk-return profiles are remarkable historical evidence for advisors.
While the Bitcoin price has fluctuated around $67,000 in recent days, it is also moving above the average entry price of new institutional investors. In the analysis, it was pointed out that the holding strategy in the three-year and longer term comes to the fore compared to historical data, while the price level in the short term is of secondary importance in this strategy.
