The Winklevoss Bitcoin Trust of Tyler and Cameron Winklevoss, has changed the desired venue for its listing, according to a preliminary prospectus it filed with the SEC. The shares will be listed and traded on Bats BZX Exchange, Inc. (BATS) under the ticker symbol ‘COIN’.
The Winklevoss Bitcoin Shares will represent units of ownership in the trust, whose sole purpose is to hold bitcoin. The instrument will be based on the spot price at Gemini, the cryptocurrency exchange founded by the Winklevoss twins.
Regarding all the important issue of cyber security in the cryptocurrencies world, the prospectus details that the private keys that control the trust’s bitcoin are secured and stored completely offline using “state-of-the-art, proprietary Cold Storage System”. It explains that this system is founded on the principles of building defense-in-depth against external threats; protecting against human error; and guarding against misuse of insider access.
Tamper-resistant computers are used to sign the transfer of bitcoin and all signers are stored, as well as backed up, in various geographically distributed, access-controlled facilities throughout the United States. It utilizes multiple-signature (Multisig) technology with an ‘M-of-N’ signing design that requires a signature from more than one signer in order to move the bitcoin. In addition, the operation of a signer requires the coordinated actions of multiple employees to protect against insider malfeasance.
Earlier this month Gemini opened Bitcoin and Ethereum trading for registered customers in the UK. In May it was authorized by the New York State Department of Financial Services (DFS) to offer the trading of Ethereum in the US.
