国際タスクフォース、8億1500万ドルの仮想通貨詐欺ネットワークを摘発

The statement's core claims—that an international operation dismantled a major crypto fraud network—are strongly corroborated by two highly authoritative and relevant primary sources: an official press release and a social media post from Europol. Both sources confirm an international takedown of a cryptocurrency fraud and money laundering network. The primary discrepancy lies in the exact value. The sources state the network laundered 'over EUR 700 million' (approximately $760 million USD), whereas the statement claims a more specific '$815 million.' This difference does not represent a direct contradiction. The phrase 'over EUR 700 million' establishes a minimum value, and the $815 million figure could represent a more precise or updated valuation, or be the result of a different currency conversion rate. Given that the fundamental event is confirmed by the most credible sources possible, the statement is assessed as likely true, with the slight numerical variance being the only point of minor uncertainty. The other provided sources are irrelevant as they either discuss general fraud prevention or entirely different criminal cases.
