Bitcoin has jumped above $80,600, up roughly 4.5% over the past 24 hours, while Ethereum is gaining almost 7% near $2,435. XRP has reached $1.33, Solana is approaching $98, and Zcash is up more than 12%. The strongest catalyst appears to be coming from traditional markets, where a weaker U.S. dollar, falling Treasury yields and a broader risk-asset rally are giving crypto some breathing room.
