COINOTAG News reported on August 28, citing LookIntoChain monitoring, that Whale 0xa523 continued to expand an ETH 15x long position. The trader’s current notional exposure reaches 86,845 ETH ($3.977 billion), with a reported liquidation price of $4342.8. Elevated leverage has increased open interest and concentration risk in ETH derivatives markets; market participants should monitor margin requirements, mark‑price dynamics and order‑book liquidity to assess short‑term stress. Exchanges and institutional desks typically track large on‑chain positions to manage counterparty and systemic risk. This on‑chain observation reflects monitoring data from LookIntoChain as reported by COINOTAG News and does not constitute investment advice; readers should corroborate on‑chain metrics and exchange reports before making trading decisions.
