According to StockMKTNewz, the US stock market opened significantly lower today, with all major indices showing red at the start of trading (source: StockMKTNewz on Twitter, June 13, 2025). Historically, major downturns in US equities have led to increased volatility in the cryptocurrency market, particularly for BTC and ETH, as traders seek alternative assets or liquidity. Crypto traders should monitor correlations between equity sell-offs and short-term price swings, as risk-off sentiment in stocks often triggers increased volume and sudden moves in major cryptocurrencies.
