The assessment is based on strong, consistent evidence from multiple sources that directly address the claim. Three sources (Phemex News, Coinness, and Coinstats) explicitly report that Founders Fund reduced its stake in Bitmine by half. One of these reports even specifies the remaining number of shares, adding a layer of detail and credibility to the claim. While these sources have moderate authority scores (0.60-0.70), their relevance to the statement is extremely high, and their reporting is consistent. The other provided sources, despite having higher authority scores, are not directly relevant to the claim of a stake reduction. They are press releases or articles concerning other corporate events, such as CEO appointments or crypto holdings. These documents confirm that Founders Fund is (or was) a major investor, which provides important context but does not contradict the reports of a sale. The absence of information about the sale in these announcements is not contradictory evidence; companies do not typically announce changes in their investors' holdings in press releases about unrelated topics. Since there is direct, corroborating evidence for the statement and no contradictory evidence, the statement is assessed as likely true with a high degree of confidence.
