The CoinShares report shows that the traditional 60/40 investment portfolio (60% stocks and 40% bonds) is no longer suitable for the current market environment, and adding Bitcoin to the investment portfolio can significantly improve risk-adjusted returns. Allocating 4% of Bitcoin to the 60/40 portfolio increases the Sharpe ratio (a measure of an investment's return relative to its risk) from 0.48 to 1.05 and reduces the portfolio's correlation. Analysis suggests that the optimal Bitcoin allocation ratio is between 4-10%, which can significantly improve portfolio performance while maintaining reasonable risks. (Coinshares)
