On-chain analyst Yu Jin said Machibigbrother grew about $150,000 into $12.3 million in August by repeatedly adding to long ETH positions as ETH rose from about $1,900 to $2,500. According to Odaily, ETH then traded between $2,400 and $2,600 in September, and Machibigbrother suffered multiple stop-losses on highly leveraged positions, cutting account equity to about $1 million. Yu Jin added that if ETH falls another few dozen to $100, the remaining position could be liquidated. Earlier, Machibigbrother reportedly closed BTC and HYPE long positions yesterday.
