The timing portion of the statement is corroborated by both BlockBeats and PANews, which independently report that CZ said he would host a Binance Square AMA at 21:00 GMT+8 on April 15 and both point back to the same CZ X post. The Odaily trace also identifies that X post as the upstream source. However, the direct fetch of the primary source at https://x.com/cz_binance/status/2044237628489511308 failed, and the fetched secondary reports do not substantiate the added claim that 10 signed copies of CZ’s new book would be given away. Because a key part of the statement remains unverified from the gathered evidence, the overall claim is best assessed as insufficient_evidence rather than fully likely_true.
