machibigbrother grew about $150,000 into $12.3 million in August by repeatedly leveraging ETH long positions as the token rose from roughly $1,900 to $2,500. In September, ETH traded between $2,400 and $2,600, while high-leverage position management led to multiple stop-losses and reduced the account's net value to about $1 million. Remaining positions could be fully liquidated if ETH falls by several dozen to $100. machibigbrother had already closed long positions in BTC and HYPE the previous day, according to blockchain analyst Ember's monitoring cited by Odaily.
