Bitcoin and altcoins have lost momentum since last week’s surge, with BTC near $82,000 and Ethereum around $2,650. Despite ETH’s decline, large investors accumulated more than 320,000 ETH over the past week, according to cryptocurrency analyst Ali Martinez. Ethereum transactions worth more than $1 million rose from 1,202 to 7,113, an increase of approximately 500%. Martinez identifies the $2,750 area as a key resistance level that ETH must break and hold to confirm buyer control. Ethereum also faces a supply wall (concentrated selling pressure) between $2,722 and $2,822, where more than 13.3 million ETH previously changed hands. If ETH clears $2,750, analysts are watching $3,400 as a key target. The analysis is not investment advice.
