币界网报道：Bitcoin's price surged to an all-time high above $72,000, driven by strong inflows into spot Bitcoin ETFs and growing institutional interest. Coinbase, the largest U.S. crypto exchange, saw its stock price jump over 9% as trading volumes spiked amid the rally. Meanwhile, the exchange faces mounting legal pressure, with a U.S. judge allowing a lawsuit alleging Coinbase sold unregistered securities to proceed. The case centers on claims that tokens like Solana (SOL), Polygon (MATIC), and others traded on Coinbase qualify as securities under U.S. law. Separately, Coinbase is also battling the SEC over whether its staking services violate securities regulations. Despite regulatory headwinds, Bitcoin's rally has reignited bullish sentiment, with analysts pointing to ETF demand and the upcoming halving as key catalysts. Publicly traded Bitcoin miners like Marathon Digital and Riot Platforms have also benefited, with shares rising sharply. The renewed optimism comes as MicroStrategy announced another $800 million Bitcoin purchase, further cementing its position as the largest corporate holder of BTC. However, some caution remains as derivatives data shows traders are heavily leveraged, increasing the risk of a sharp pullback if volatility spikes.
