Mr Bailey's comments came after another volatile session for Bitcoin, which the Governor last year said lacked "intrinsic value".
European Central Bank president Christine Lagarde last week called the crypto-currency a "highly speculative asset which has conducted some funny business and some interesting and totally reprehensible money-laundering activity".
The price of Bitcoin - described by one market participant as "tulip mania" - has veered wildly this year, topping US$40,000 (NZ$55,500) on January 8 and then crashing below US$30,000 last week in its biggest sell-off since March.
The price bounced again to US$33,845 on Monday.
