U.S. derivatives regulators are providing more time for public feedback on the possible registration of a firm seeking to facilitate trading in Bitcoin derivatives.

The U.S. Commodity Futures Trading Commission (CFTC) said Tuesday it is extending the deadline for public comments on an application from LedgerX, LLC; a firm that plans to list and clear fully collateralized, physically settled options on the virtual currency, Bitcoin.

The firm is seeking registration as a derivatives clearing organization and as a swap execution facility. The original comment period on its applications ended on Jan. 30, but in response to requests for additional time, the CFTC is extending the deadline to Feb. 20.
