The evidence overwhelmingly supports the statement that Huang Licheng (also known as Machi Big Brother) made a profit from Ethereum (ETH) long trades. Multiple high-authority sources, including news outlets from major crypto exchanges like MEXC, Bitget, and Binance, corroborate this fact. These sources, often citing on-chain data analysis from firms like Lookonchain and Ember, report profits vastly exceeding the $100,000 mentioned in the statement. For instance, different reports confirm profits of $3.5 million, $33.83 million, $42.6 million, and even $44.5 million specifically from his ETH trading activities, including long positions.One source directly states he closed ETH long trades for a profit of $33.83 million. Since making a profit of several million dollars necessitates also having made a profit of $100,000, the statement is a conservative but factually accurate representation of his trading success during that period. The evidence confirms both the specific activity (ETH long trades) and the outcome (profit).The only contradictory information comes from a single, very low-authority Facebook post mentioning losses. However, the high-authority sources also acknowledge liquidation risks and subsequent losses, but they frame these events as occurring *after* he had already secured tens of millions in profits. Therefore, the existence of losses does not negate the fact that significant profits were made beforehand. The consistency and high authority of the supporting evidence far outweigh the weak, contradictory claim, leading to a high confidence assessment that the statement is true.
