The Winklevoss ETF was intended to do the following:
* ETF would hold spot BTC bought via Gemini.
* NAV would be based on Gemini's daily auction.
* Each share was set to be worth 0.01 BTC.
- SEC believes the spot market has too much potential for manipulation.
- States that only using Gemini isn't good enough & that it's too low volume/liquidity.
- Says that: "(No) current trading venue in the worldwide bitcoin spot market is a regulated market."
Winklevoss ETF was accessible to retail b/c it was set to 0.01 BTC per share, making it less likely to be approved.
The VanEck proposal sets each share to be worth 25 BTC -- thus restricting access.
The VanEck proposal is more advanced than this using OTC markets for the NAV & incorporating multiple exchanges into it.
