answers 402

S&P 500, gold and Nasdaq 100 quotes as the traditional-market leg of a crypto read. BTC trades as a high-beta risk asset far more often than as digital gold, so equities direction is usually the better correlation to check before blaming a crypto-native cause. Priced as ETFs, so use direction and percent change, not the absolute level.
