Ethereum extended its breakout after buyers defended support near $2,560 and pushed ETH to $2,712 between Sept. 20 and Sept. 21. The token settled around $2,700 as trading volume increased, while RSI (relative strength index, a momentum gauge) rose to 68.66, nearing but not exceeding the 70 level commonly associated with overbought conditions. Whale buying added support after wallet 0x4cee purchased 7,567 ETH worth about $19.9 million after transferring stablecoins to Binance. The same wallet had sold 10,500 ETH a month earlier at an average price of about $2,252 per ETH, securing $3.66 million in profits. Derivatives markets also aided the move: Hyperliquid held roughly $3 billion in ETH open interest (the value of active contracts), with funding slightly positive, while short liquidations reached $170 million. The breakout still requires sustained spot buying to replace temporary liquidation-driven demand. Holding $2,700 could expose $2,760, while a break below $2,600 could weaken momentum.
