This week, BTC fluctuated within the 74,800-79,000 range, with the Federal Reserve's interest rate decision (early morning of 4/30) as the core variable. High interest rates suppress valuations, and ETF capital support is limited. In the short term, the market is biased toward weak oscillation, with rebounds only serving as corrections. The main strategy is to go short on rallies and buy on dips, with key levels at 76,000-79,000. Position sizes should be strictly controlled with stop-losses, waiting quietly for the decision to guide the direction.
