Three separate contemporaneous X posts — x post 2046333254983102909, x post 2046335973173170389, and x post 2046530129854108030 — independently attribute substantially the same quote to BlackRock executive Jay Jacobs in comments to Fox Business: that Bitcoin is driven by its own rules and can provide value to portfolios. The KuCoin result snippet also mirrors the same claim. However, because no direct Fox Business clip/transcript or BlackRock official post was retrieved in this run, confidence is medium rather than high.
