Winklevoss twins on Wednesday filed to switch the listing of The Winklevoss Bitcoin Trust, their proposed bitcoin exchange-traded fund, to BATS Global Markets from Nasdaq, according to a regulatory filing with the Securities and Exchange Commission.

Cameron and Tyler Winklevoss had first filed the application for a listing three years ago. According to the recent filing, the proposed ETF will list 1 million shares at $65 each – up from a list price of $20.09 per share given in the first filing, Reuters reported.

Bats Global Markets is a leading global operator of exchanges and services for financial markets. Earlier this month, it announced May data and highlights which included 13 ETF listings to the Bats ETF Marketplace and announced Deutsche Asset Management as the third ETF issuer to switch primary listings to the Bats ETF Marketplace. As of June 10, the Bats market has 12 US issuers with 95 ETFs listed.

If approved by the regulator, the Winklevoss ETF would become the first bitcoin ETF issued by a U.S. entity. It would trade under the ticker symbol “COIN”.

The filing also stated that Gemini Trust Company, founded by Winklevoss brothers, has been designated as the custodian of the ETF. Last year, Gemini Trust Co. received a limited liability trust charter from the New York State Department of Financial Services (NYDFS), holding it to the regulatory standards of a trust bank and allowing it to operate as a regulated financial-services institution. In May, Gemini announced its support for ether trading.

In addition, Digital Asset Services, LLC, a Delaware-based limited liability company formed on May 9, 2013, and wholly-owned by Winklevoss Capital Management, LLC., has been named as the sponsor of the Trust.
