Justin Zhu

Justin Zhu is a declared insider at 2 companies; the most frequent names are Bit Digital, Inc and WhiteFiber, Inc. We count 10 filings; the first trade dates from 25 July 2025 and the latest from 15 October 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The record was last updated on 16 October 2026 with a share grant (€36k) in WhiteFiber, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
