Cathie Wood: Bitcoin will become an effective portfolio diversification tool in the coming years According to Cryptobriefing, ARK Invest CEO Cathie Wood stated in her 2026 outlook that Bitcoin, due to its low correlation with major asset classes like gold, stocks, and bonds, is expected to offer higher risk-adjusted returns for asset allocators and become an effective portfolio diversification tool in the next few years. Wood believes that Bitcoin's protocol strictly limits its supply growth, with the annual growth rate of new issuance expected to be around 0.8% over the next two years, slowing further to approximately 0.4% annually thereafter. This mathematically fixed supply gives Bitcoin inherent scarcity. She pointed out that the predictable supply model, combined with increasing demand, has driven Bitcoin's price up by 360% since the end of 2022.
