The strongest available evidence is the original-source provenance: the Odaily newsflash traces directly to https://x.com/lookonchain/status/2045837716991201344, and the PANews article '某交易者“卖飞”74.3亿枚ASTEROID,错失260万美元利润 | PANews' repeats the same concrete figures: 7.43 billion ASTEROID, bought for $542, sold for $405, one day before a surge, with later value above $2.6 million. These details align closely with the user's statement. Confidence is only medium because direct web_fetch validation of the X post failed, so the primary post itself could not be substantively fetched in this run.
