News: Bitcoin has shown significant bullish momentum today, breaking past the $4,100 resistance level with a rapid 5% surge in just two hours, boosting other major cryptocurrencies. This price action, coupled with a rising market cap and positive correlation with the strong US stock market rally, suggests a bullish short-term outlook. However, mixed movements in some altcoins and the ongoing uncertainty around ETF approvals in Korea (dependent on the SEC) introduce some caution. The development of new Bitcoin valuation models and continued institutional interest from entities like Rakuten and Digital Currency Group provide long-term optimism.
