Bitcoin and Ethereum behave very differently during periods of geopolitical tension. Historically, BTC has shown an inconsistent relationship with global risk — sometimes acting as a safe haven (rising with gold during market stress), and sometimes selling off alongside equities when institutional investors seek liquidity.

ETH tends to track broader risk sentiment more closely than BTC, making its Fear & Greed score a useful proxy for overall crypto market appetite. When ETH scores below 30 (Fear territory), it often signals capitulation — historically a buying opportunity for longer-term holders.

Bitcoin dominance — BTC's share of total crypto market capitalisation — is a key indicator of market cycle phase. When dominance rises above 55-60%, it typically means capital is rotating out of altcoins into BTC, often preceding a broader market downturn or a BTC-specific rally. When dominance falls, altcoins are outperforming.

The combined Crypto Fear & Greed score weights BTC at 60% and ETH at 40%, reflecting their relative market capitalisation. Scores below 25 indicate Extreme Fear — periods that have historically preceded significant market recoveries over 6-12 month horizons.
