Bitcoin's dominance in the cryptocurrency market could fall to 40% by September 2024 as the rise of altcoins continues to gain momentum. The growing interest in decentralized finance (DeFi), NFTs, and other blockchain technologies is driving this shift, leading to a more balanced and competitive market. Investors are increasingly diversifying their portfolios, seeking out projects that offer new and innovative use cases. As the market evolves, Bitcoin's role may diminish slightly, reflecting a broader range of significant cryptocurrencies. While BTC will remain a key player, its dominance could see a reduction as the market matures.
