According to Crypto Rover, Coinbase ($COIN) shares are experiencing a significant surge, raising questions about the potential for a bullish move in Ethereum ($ETH) as well. As reported by Crypto Rover on June 21, 2025, the rapid appreciation in Coinbase stock often signals increased institutional and retail interest in the broader crypto sector, particularly blue-chip assets like ETH. Traders should monitor $COIN's momentum closely, as historically, strong Coinbase performance has preceded inflows into major cryptocurrencies. This correlation could lead to heightened volatility and new opportunities in ETH trading in the near term (source: Crypto Rover on Twitter).
