According to Crypto Rover (@rovercrc), large Ethereum holders are aggressively accumulating ETH, indicating strong confidence in an imminent altcoin season. On-chain data shows a significant uptick in whale wallet activity, which historically signals upward price momentum and increased volatility for Ethereum and related altcoins. Traders should monitor ETH inflows to whale addresses, as sustained accumulation often precedes broad altcoin rallies and shifts in market liquidity. Source: Crypto Rover on Twitter, May 16, 2025.
