Evening BTC main idea: Range-bound with a slight bullish bias, mainly buying on dips, avoid chasing rallies and panic selling

Low-buy opportunity: When retracing to 80,500-80,700 and finding support, go in with a small position, set stop loss at 80,300, first target 81,300, take half profit when reached, keep the rest to break even

Shorting opportunity: When surging to 81,800-82,000 and volume increases without a rally, try shorting with a small position, stop loss at 82,200, target 81,300-80,800, only attempt once, do not add to positions repeatedly#比特币波动
