Bitcoin has fallen below the $90,000 mark, and a new 4-hour level decline has officially begun. Any small rebound within the day could be an opportunity to look for shorting opportunities. Ethereum's trend is generally following, and a rebound is expected for technical correction. The key point to watch is whether the price can effectively recover above $3,250 to temporarily halt the decline. The market's short-term structure has weakened, so the trading strategy should shift to a rebound and short approach.

The Federal Reserve cut interest rates by 25 basis points as expected, but Powell's hawkish remarks emphasized "reducing the likelihood of rate cuts next year," which increased market concerns about future liquidity easing. The positive effect of the rate cut has not met expectations.
