CBOE CEO Edward Tilly told the Financial News that recent criticism about bitcoin futures was “uncalled for”; “I think letters like that and cheap shots to our regulator, the CFTC, are uncalled for to make it seem this was an overnight self-certification without the proper amount of CFTC involvement,” explained Mr. Tilly; he explained that the Options Clearing Corporation clears the contracts for the CBOE and was comfortable with their decision of bitcoin.
