News: Bitcoin experienced a mixed day, trading within a range after a recent rally, with key support levels being tested. Positive developments include the potential approval of a Bitcoin ETF and the launch of Bitcoin options by CME, signaling growing institutional interest. However, macro uncertainty from the upcoming Fed decision and China's continued focus on its own blockchain initiatives, rather than Bitcoin, temper immediate bullish sentiment. Altcoins like BCH and ETH showed stronger short-term gains.
