The strongest direct support is the BlockBeats flash '某鲸鱼从Binance提取597万枚ASTER,价值399万美元', which explicitly matches the claim and its added context about prior interaction with Aster. However, this is still secondary reporting attributed to OnchainLens. I attempted corroboration through the linked Odaily item and traced source. The traced Arkham page 'https://intel.arkm.com/explorer/address/0x026447a649e8A9DcAb4b49d94e5006f98A4D600d' did not yield claim-specific evidence in the fetched content, and X/web searches for the underlying OnchainLens post did not return usable corroboration in this run. The separate BlockBeats item '某新建地址从Binance提取1000万枚ASTER,价值670万美元' shows related ASTER withdrawal reporting on the same date but does not verify this exact 5.97 million ASTER event. Therefore the claim is plausible and partially supported, but not sufficiently verified from primary sources here.
