Bitcoin is the best crypto to buy now for a core position, while Ethereum is the higher-beta trade with a dated catalyst. BTC trades at $78,456 on October 30 after touching a six-week low of $76,500 overnight, ETH sits at $2,246 with its Glamsterdam scaling upgrade in final testnet, and XRP holds $1.26 after Ripple won a federal trust-bank charter for its RLUSD stablecoin. Three large-cap assets, three live catalysts, and one broad selloff that has yet to find a floor.
