Coinone、Coinbaseへの持分売却交渉を否定

The assessment is primarily based on a highly authoritative and relevant news article from a crypto-focused outlet. The summary of this source explicitly mentions that it contains a statement from "Coinone officials" regarding the takeover talk, which directly pertains to the claim being evaluated. Two other relevant sources, while not containing the denial itself, establish the necessary context by reporting on the widespread rumors that Coinbase was exploring an equity investment in Coinone. The existence of these rumors makes an official denial from Coinone a plausible and newsworthy event. There is no contradictory evidence among the provided sources. The remaining two sources are entirely irrelevant to the topic. Therefore, the combination of direct, high-authority evidence and supporting contextual information strongly indicates that the statement is true.
