According to Michaël van de Poppe (@CryptoMichNL) on Twitter, traders should expect extreme volatility in Bitcoin and Ethereum prices during the period between the Federal Reserve's announcement and Jerome Powell's presentation. He advises against trading during this window due to unpredictable price swings, emphasizing that the significant market move is likely to occur afterward. van de Poppe also notes that expectations of quantitative easing (QE) could drive further momentum in the crypto markets following the event (source: https://twitter.com/CryptoMichNL/status/1920160308011643076).
