Ethereum (ETH) is encountering a significant resistance zone between $3,170 and $3,270, marked by a concentration of ETH held by 1.63 million addresses totaling 4.45 million ETH. This accumulation could determine whether ETH can surpass the $3,650 level. Analysts highlight the potential sell-off point within this zone, which could lead to increased selling pressure if holders decide to take profits. Breaking through this barrier could propel ETH toward $3,650. However, failure to maintain support at $3,000 may lead to a drop towards $2,850.
