Given the current market environment, trading four-hour swing trades with a light position for trial and error is sufficient. Having experienced extreme volatility in a bull market, there's no need to be overly persistent about direction in a bear market—short when resistance stalls and rises when support stabilizes. Place stop-losses at the point of structural breakdown, and with a risk-reward ratio greater than two, participation is justified. Technically, on the four-hour chart, focus on the divergence direction after EMA moving average convergence, combined with MACD histogram divergence; tops and bottoms often appear after a volume spike and retest confirmation. Relying on intraday pullback lows and previous breakout points as defense, a breakout suggests following the trend to short, while a pullback without a breakout indicates a long for a rebound.

Currently, after Bitcoin's rally, observe the recovery strength; if the support at 71,500 holds, continue to look upward toward 73,300-73,800. If it breaks below, consider around 70,500-70,000 for a long attempt.

Ethereum, if it does not break below 2,200, continues to look for a rebound, targeting 2,270-2,350. If it breaks below, try a long around 2,150-2,120.
