ETH 4000~4060 is a key support zone. If this range is broken, more traders might turn bearish. Before reaching this zone, the bulls will struggle, but buying pressure is clearly weak. Since we already know the script, we should start thinking about the next dip-buying strategy. I believe the extreme level for these three waves of sell-offs is around 3600, but we won’t wait until 3600 to start buying. Don’t expect to catch the absolute bottom. If ETH breaks support and drops below 3900, Lao Yu thinks it’s a good time to start buying ETH and your preferred altcoins in batches.
