Jeffrey Huang's public career runs across three near-unrelated domains that all end up at the same wallet. Before he was a DeFi founder he was a member of L.A. Boyz, the late-1990s Taiwanese-American hip-hop group. By 2020 he had co-founded Cream Finance, one of the lending protocols that defined the DeFi-summer cycle. By 2024-2025 he was running the largest publicly-identifiable ETH-long perp positions on Hyperliquid under the X handle @machibigbrother, with the on-chain identity verified through the ENS machibigbrother.eth resolving back to the wallet his audience tracks daily.

The 2025 Hyperliquid arc is the part of the career most-cited in current coverage. From a peak unrealized +$44M during the Q3 2025 ETH rally, his cumulative position-history drew down through Q4 toward roughly -$28M, then deteriorated into a -$71M cumulative net loss across a 4-month window after the Oct 11 2025 crash — 145 separate liquidations attributed to his wallet in the post-crash sequence. The trades are mostly ETH longs at 10-25x leverage, margin frequently added into drawdowns rather than cut, and the position-management style is closer to "ride the conviction" than systematic risk control.

The reason he stays on the leaderboard isn't the PnL — it's the public-figure surface. The ENS-anchored wallet, the X handle, and the dense Cointelegraph / KuCoin / MEXC News coverage make him one of the few Hyperliquid whales with a fully-doxxed identity. Lookonchain and on-chain analysts run live PnL updates against his trades because the audience reads it the way prior generations read open positions inside CTAs. Treat the page as the canonical Hyperliquid "public-figure trader" case study, not as a championship-results entry.
