BitMEX, a Hong Kong-based cryptocurrency derivatives trading platform, has announced the launch of a prediction futures contract that will allow traders to bet on whether the Winklevoss Bitcoin Trust ETF will get approval from the SEC, CoinDesk reported.

Cameron and Tyler Winklevoss, the co-founders of Gemini bitcoin exchange, had first filed the application for a listing in 2013. In June 2016, the twins filed to switch the listing of The Winklevoss Bitcoin Trust to BATS Global Markets from Nasdaq. Later in October, they announced that they have chosen State Street as the administrator and transfer agent for the Winklevoss Bitcoin Trust.

Whether this proposed bitcoin exchange-traded fund (ETF) will get the SEC approval or not is being highly debated.

Recently, Needham & Company released a report examining the prospects of the Winklevoss twins’ proposed bitcoin ETF. Spencer Bogart, a research analyst at Needham & Company and author of the report, saw a very low probability (sub-25%) of a bitcoin ETF getting approval in 2017.

As the speculation is building up, BitMEX has launched the COIN contract. The futures contract is binary, meaning it will either settle at 0 or 100.

“COIN will settle at 0 if the SEC does not approve the proposed rule change. COIN will settle at 100 if the SEC approves the proposed rule change”, the website reads.
