Saylor’s Strategy Acquires Additional 390 Bitcoin, Total Holdings Reach 640,808 BTC

The assessment is based on overwhelming and consistent evidence from highly authoritative and relevant sources. The most crucial evidence comes directly from Michael Saylor's official X account, which serves as the primary announcement. This source explicitly confirms both parts of the statement: the acquisition of 390 Bitcoin and the new total holding of 640,808 BTC.This primary announcement is strongly corroborated by multiple independent news outlets focused on the cryptocurrency industry, including The Block, CryptoPotato, and Chaincatcher. Each of these secondary sources independently reports the exact same figures, lending significant credibility to the claim.Several other provided sources, such as older SEC filings and press releases, describe past acquisitions with different numbers or outline the company's general strategy. While these sources are authoritative, their low relevance means they neither support nor contradict the specific claim in question; they are simply outdated or provide general context. There is no conflicting evidence among the provided materials.In summary, the statement is directly verified by the primary source (the company's leader) and confirmed by numerous secondary sources, making it highly likely to be true.
