This study explores the diversification potential of cryptocurrencies in traditional investment portfolios and their impact on portfolio performance. Focusing on Bitcoin, Ethereum, and Binance Coin, this research examines their return characteristics, volatility, and correlation with conventional asset classes. A portfolio optimization approach using Minimum Variance and Maximum Sharpe Ratio strategies is applied to assess the benefits of including these digital assets. Historical data from 2019 to 2024 is utilized to compare cryptocurrency-inclusive portfolios with those composed solely of traditional assets such as bonds, gold, and equities.

The findings reveal that integrating cryptocurrencies enhances portfolio returns and improves risk-adjusted performance, with Ethereum and Binance Coin emerging as key return drivers. This study highlights how cryptocurrencies offer unique diversification benefits due to their low correlation with traditional assets, providing investors with new opportunities for optimizing risk and return. Additionally, portfolio optimization results demonstrate that the strategic allocation of digital assets can significantly enhance performance without compromising overall portfolio stability.

By offering empirical evidence on the role of cryptocurrencies in investment strategies, this study contributes to the growing body of research on digital asset integration. The results provide valuable insights for investors and portfolio managers seeking to enhance diversification and capitalize on the evolving financial landscape.
