Major cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), and Dogecoin (DOGE), experienced significant gains as the market anticipates the approval of the first spot-based Bitcoin ETFs in the U.S. Asset management firms like BlackRock, Fidelity, and Grayscale have updated their S-1 filings with the SEC, revealing their fee structures. Bitwise offers the lowest fee at 0.24%, while BlackRock set its fee at 0.30%. The global cryptocurrency market cap slightly declined, while stock averages increased, with the S&P 500 and Nasdaq Composite rising. Analysts predict a bullish cycle for Bitcoin, with the upcoming ETF approval and the Bitcoin Halving event serving as potential catalysts.
