The key factual statement is explicitly present in the validated PANews article titled 'ETH跌破2300美元,日内下跌 2.71% | PANews', which says OKX market data showed ETH at $2,299.68 after falling below $2,300. A second validated PANews article, 'ETH跌破2300美元,日内下跌 1.31% | PANews', shows a similar update at a different time with slightly different figures, which is consistent with normal market movement rather than disproving the first item. Attempts to corroborate through the provided Odaily links and general web search did not yield stronger independent evidence, so confidence is medium rather than high.
