MILAN, Feb 19 (Reuters) - Introducing the digital euro could cost European banks between four billion and six billion euros ($4.7-$7.1 billion) spread over four years, a senior European Central Bank policymaker said on Thursday.
ECB Governing Council member Piero Cipollone also said the new digital-only central bank currency is estimated to cost the ECB around 1.3 billion euros to set up.
