According to Crypto Rover, exchange-traded funds (ETFs) have become the largest holders of Bitcoin, surpassing other institutional and retail investors. This surge in ETF holdings signals a strong wave of institutional adoption, which is typically interpreted as a bullish indicator for Bitcoin's price trajectory. For traders, the growing concentration of Bitcoin in ETFs suggests continued upward momentum and increased liquidity, making the market more attractive for both long-term investors and active traders (source: Crypto Rover on Twitter, April 30, 2025).
