币界网报道：Bitcoin's market capitalization has surged past $2.128 trillion, overtaking Google's parent company Alphabet to become the world's fourth most valuable asset. The cryptocurrency reached this milestone as its price climbed above $43,000, demonstrating remarkable growth despite recent market volatility. This achievement places Bitcoin behind only gold, Microsoft, and Apple in terms of market value. The rally comes amid increasing institutional adoption and growing recognition of Bitcoin as a store of value and hedge against inflation. Analysts attribute the surge to several factors including the approval of spot Bitcoin ETFs in the U.S., the upcoming Bitcoin halving event in 2024, and macroeconomic uncertainties driving demand for alternative assets. The cryptocurrency's market cap now exceeds many traditional tech giants, signaling a significant shift in investor sentiment toward digital assets as a mainstream investment class.
