According to COINOTAG News on September 12, monitoring by Emmett Gallic identified a pre-listing transfer of 350 BTC from the Gemini Custody address attributed to Winklevoss Capital. The report states the firm plans to periodically sell or donate small tranches from its 17,000 BTC reserve. Blockchain analytics validate the on-chain provenance of the transfer, and the activity is consistent with routine treasury management ahead of a potential exchange listing on Gemini. Market participants should monitor formal custodial disclosures and exchange filings for confirmation of future distributions and any consequent shifts in circulating supply.
