币界网报道：Bitcoin is poised for its highest weekly close of the year, fueled by growing institutional interest and positive market sentiment. The cryptocurrency surged past $42,000 this week, marking a significant rebound from its recent lows. Analysts attribute the rally to increased inflows into Bitcoin ETFs, with major financial institutions like BlackRock and Fidelity reporting substantial investments. Market data shows over $1 billion in net inflows into Bitcoin ETFs since their launch, signaling strong demand from institutional players. Additionally, macroeconomic factors such as potential Federal Reserve rate cuts and a weaker U.S. dollar have contributed to Bitcoin's upward momentum. Traders are closely watching key resistance levels around $45,000, which could pave the way for further gains if breached. The bullish trend is also reflected in rising open interest in Bitcoin futures, indicating heightened trading activity. Meanwhile, altcoins like Ethereum and Solana have followed Bitcoin's lead, posting double-digit percentage gains. Industry experts suggest the current rally may sustain if institutional adoption continues to grow, though caution remains due to potential regulatory developments. The crypto market's total capitalization has crossed $1.6 trillion, its highest level since early 2022, as investor confidence returns.
