The evidence strongly supports the truthfulness of the statement. The core of the assessment rests on two key pieces of information that work in tandem. First, a reputable financial data source, MarketBeat, confirms the underlying premise of the claim: that Norway's Sovereign Wealth Fund (via Norges Bank) holds shares in MicroStrategy (MSTR), a company known for its significant Bitcoin holdings. This establishes the mechanism for the fund's indirect Bitcoin exposure, making the claim plausible.Second, the TradersUnion news article directly reports the specific 149% increase and, most importantly, attributes this calculation to a research firm named 'K33'. By citing a specific analytical source, the claim is elevated from a mere headline to a reported finding. While we don't have the original K33 report, a secondary source citing its primary analytical source is strong evidence. This is corroborated by another news source (ETHNews), though its credibility is slightly diminished by summary notes. There is no conflicting evidence among the provided sources. The other sources are irrelevant, as they either link to general homepages or discuss unrelated topics. The combination of primary data confirming the mechanism (MarketBeat) and a specific, attributed analysis reported by news media (TradersUnion) makes the statement highly likely to be true.
