The assessment is 'likely_true' with high confidence based on strong circumstantial evidence from highly authoritative sources, even without a direct primary source confirming the exact figures.The most critical evidence comes from the combination of sources establishing Coinglass as the definitive primary data aggregator for cryptocurrency liquidations and a report from The Block, a highly credible crypto news outlet. The Coinglass sources confirm that this type of granular data (liquidations by position type, asset, and timeframe) is systematically tracked. The Block's article reports on a massive '$1.7 billion' liquidation event over a 24-hour period, explicitly citing Coinglass as its source. This report accomplishes two things: it validates Coinglass's authority and establishes that liquidations in the hundreds of millions or even billions are a documented reality in crypto markets. A liquidation of $525 million within a single volatile hour is entirely plausible within the context of a multi-billion dollar daily event.While other sources mention different figures or use the term 'liquidate' in an unrelated context, they do not contradict the claim's plausibility. For instance, the source mentioning a '$300 million' liquidation of long positions, although a different event, reinforces that such specific events occur and are reported. The irrelevant sources, such as the one confusing liquidation with trading volume, are easily dismissed due to their low authority and clear misinterpretation of the terms.In summary, while no provided link points to the specific historical data for the '$525 million in one hour' event, the combination of a designated primary source for this data (Coinglass) and a reputable secondary source (The Block) reporting on a similar, much larger event makes the statement highly probable.
