  [Comprehensive News Analysis]
  Summary: The market is reacting to the Federal Reserve's decision to accelerate stimulus withdrawal, with Bitcoin showing resilience and even jumping initially, defying bearish expectations. Positive developments in regulated products, such as Coinbase backing the GBTC ETF conversion and the launch of an Ethereum ETP, are providing bullish signals. However, regulatory scrutiny on crypto advertising in the UK and bearish predictions from industry figures like Mike Novogratz introduce some short-term headwinds. The overall sentiment is cautiously optimistic, with key support levels holding for Bitcoin.
