According to Crypto Rover, Bitcoin (BTC) and Ethereum (ETH) experienced significant sell-offs following verified reports of a ground attack on Iran's Fordow nuclear facility (source: Crypto Rover on Twitter, June 21, 2025). This geopolitical escalation has triggered increased volatility and risk-off sentiment among crypto traders, resulting in sharp declines in BTC and ETH prices in the short term. Traders should closely monitor news flow and consider tightening stop-losses or adjusting positions as global uncertainty impacts crypto market liquidity and risk appetite.
