The key support positions to focus on this week for ETH are the first line at 1760 and the second line, which is the key support range of 1680-1720. If the market is not weak, there is no need to see 1680; at most, we should pay attention to the area around 1720.

First level support: 1760 (The four-hour level has tested around 1750; we need to pay attention to whether it can hold)

Second level strong support: 1680-1720 range (If the market is not weak, we can focus on around 1720)

Short-term rebound target: 1820-1860 range (If the four-hour level stabilizes, we can look towards this area)

Key resistance this week: 1960-2000 range (Need to consider the daily level breakthrough situation)

If the low of 1750 does not break, we can look for short-term rebound opportunities, targeting 1820-1860. If weakness continues, we should pay close attention to the strength of support around 1720; if it breaks, we look down to 1680.
