According to Crypto Rover, Fidelity has purchased $19,800,000 worth of ETH, a move that signals increased institutional confidence in Ethereum and the broader altcoin market (source: @rovercrc, Twitter, May 21, 2025). This substantial investment from a leading asset manager may drive upward price momentum for ETH and other altcoins, as institutional inflows often precede broader market rallies. Traders should monitor ETH and related altcoins for potential short-term volatility and long-term bullish trends, as this event could encourage further large-scale investments into the crypto sector.
