Quick opening-bell glance: Major cryptocurrencies broadly rebounded overnight, with $BTC back above 82,408.01 (+0.73% over 24h) and $ETH at 2,444.22 (+0.65%). A recovery is starting to emerge after two straight days of losses. But trading volume hasn’t picked up yet, so don’t rush to equate a rebound with a reversal—today, the key is whether the rally can extend into the U.S. trading session.#比特币 #MarketAnalysis
