If you’re excited about the idea of investing in a bitcoin-tracking exchange-traded fund, you’ll have to wait a bit longer to learn if you can—again.

The Securities and Exchange Commission on Wednesday designated March 11 as the date by which it would either approve or disapprove the Winklevoss Bitcoin Trust ETF, which would be the first to exclusively track the digital currency.

A decision would represent the end of a multiyear campaign to bring a bitcoin ETF to market. Tyler and Cameron Winklevoss, who run Winklevoss Capital, first announced plans for one in 2013; the pair also run both WinkDex, a bitcoin price index, and Gemini, a bitcoin custodian and exchange.

Winklevoss Capital didn’t immediately return requests for a comment.

What is the future of bitcoin?

The SEC has delayed issuing a ruling on the proposed ETF multiple times. In October, it declined to rule, saying it was instead seeking additional public feedback on the proposal. In a filing published on Wednesday, the SEC said it had subsequently received 30 comments.

The proposed fund, which would trade on the Bats exchange, was first published for public comment on July 14 of last year. The SEC could have ruled on it on Jan. 10—180 days after that date—but it is instead waiting until March 11, which is 240 days since July 14.

“The Commission finds it appropriate to designate a longer period within which to issue an order approving or disapproving the proposed rule change so that it has sufficient time to consider this proposed rule change,” the SEC wrote in a statement.

Because March 11 is a Saturday, the ruling could actually be announced on Friday, March 10, the final business day before the deadline.

While investors can put their money into bitcoin directly, those waiting on an ETF to get bitcoin exposure have missed out on some massive gains. The price of a single coin more than doubled in 2016, due to increasing adoption of bitcoin among professional investors, improving market fundamentals and a perception that the world’s largest economies are growing increasingly unstable.
