Machi Big Brother's ETH Long Falls to $1M

Taiwanese trader Huang Licheng, better known on-chain as Machi Big Brother, has spent the past year building a reputation as crypto's most theatrical leverage trader — the self-styled King of Crypto Liquidations, whose account has swung between tens of millions in profit and near-total wipeouts more times than most traders manage in a career. His latest run just delivered another chapter, and it followed the pattern almost exactly.

Starting in August with roughly $150,000 in principal, Machi built a rolling, high-leverage long position on Ether, adding to it as the price climbed. As ETH rose from around $1,900 to about $2,500, the strategy compounded that initial stake into an account worth approximately $12.3 million — an eighty-fold gain in a matter of weeks, the kind of run that turns a trader's every position into a spectator event on crypto Twitter, not unlike the way another Arkham-tracked leveraged trader drew a following on the way up earlier this year.

Then September happened

Ether has spent this month grinding sideways in a $2,400 to $2,600 range rather than extending the reclaim above $2,600 it managed earlier, and for a rolled, highly leveraged long, sideways chop is often more dangerous than an outright drop. Each swing through the range has repeatedly tripped Machi's stop-loss levels, and the account has been ground down from its $12.3 million peak to roughly $1 million — a decline of about 92% from the high.

On-chain analyst Ember, who has tracked the position closely, framed how little room remains:

If ETH's price drops another tens to a hundred dollars, his remaining position may be liquidated.

That is a strikingly thin buffer for an account that was worth twelve times as much three weeks earlier. A move of two to four percent in Ether — noise by the standard of this year's volatility — is now the difference between Machi walking away with a seven-figure account and losing the position entirely.

A pattern, not an outlier

This is not new territory for Machi. He has become known specifically for this cycle: aggressive, frequently 25x-or-higher leveraged long positions, mostly on Ether, that compound spectacularly on the way up and evaporate just as fast on the way down. On-chain trackers have pegged his cumulative losses on Hyperliquid at more than $80 million since last September even as individual runs like this one have periodically pushed his paper gains into eight figures. He has also carried baggage from well before his current trading persona: on-chain investigator ZachXBT accused him in 2022 of misappropriating roughly 22,000 ETH tied to failed project commitments, and a rapid sale of over 1,000 NFTs around the same period became known in crypto circles as the Machi Dump, a byword for a large holder crashing a market on the way out.

What makes the strategy so fragile

The mechanics explain why these swings happen so fast. Rolling a leveraged position means continually redeploying gains into a larger notional size rather than banking profit along the way, which maximizes upside during a sustained trend but leaves almost no cushion once price stops trending and starts oscillating. A trader holding steady leverage on a rising asset benefits from every uptick; the same trader holding rolled, compounded leverage can see a full retracement of weeks of gains from a single sharp reversal, because the position size grew precisely because the earlier gains were never taken off the table.

Whether Machi's remaining stake survives the next leg of Ether's range likely comes down to a matter of dollars rather than any broader market thesis. It would not be the first time his account has gone to zero, and on current form, it will not be a surprise if it happens again before this particular story is finished — Machi is far from the only trader whose portfolio has swung by eight figures on nothing more than a few days of volatility this year.
