The core endpoint of the claim is directly supported by Odaily's report “ETH 突破 2400 USDT ， 24H 涨幅 3.68%,” which says OKX market data showed ETH at 2400.15 USDT and up 3.68% over 24 hours. The earlier-leg recovery context is also supported by “ETH 突破 2300 USDT ， 24H 跌幅收窄至 2.9%,” which states ETH had rebounded above 2300 USDT while still down 2.9% on a 24-hour basis. Additional corroboration that ETH had recently traded below 2300 appears in both Odaily's “ETH 跌破 2300 USDT ， 24H 跌幅 2.08%” and PANews' “ETH跌破2300美元，日内下跌 2.12%.” The main limitation is that all supporting evidence here is from crypto newsflash outlets summarizing OKX market data, not a directly fetched OKX official market page or official OKX social post. Also, one supplied source shows the dip below 2300 as -2.08% rather than -2.9%, indicating the percentages refer to different timestamps during a volatile trading day rather than a contradiction. Overall, the combined narrative is plausible and well supported by the supplied reports, but confidence is only medium because the evidence is indirect.
