#ETH GN, tested yesterday's POC 4215 and briefly pulled back. If the price continues to rebound, focus on the possibility of a strong breakout; if it continues to decline, there are two key support lines: this week's POC 4200 and this month's POC 4170. If either support line holds, the overall bias remains bullish; if both support lines are breached, the risk for long positions will significantly increase.
