币界网报道:Bitcoin surged over 7% this week, reclaiming the $43,000 level amid renewed institutional interest and ETF inflows. Ethereum outperformed with a 12.2% weekly gain, climbing above $2,300 as network upgrades and staking demand boosted sentiment. Solana led the rally with a 16.5% spike, surpassing $100 as its DeFi ecosystem and meme coin activity attracted traders. Analysts attribute the broad crypto rebound to cooling US inflation data, which eased Fed rate hike fears. Market capitalization grew by $80 billion this week, with altcoins showing particularly strong momentum. Traders are now watching key resistance levels for Bitcoin at $45,000 and Ethereum at $2,500 as potential breakout targets.
