Philippine Central Bank Deputy Governor Nestor Espenilla Interview

Nestor Espenilla, deputy governor of the Bangko Sentral ng Pilipinas, gestures as he speaks during an interview in Manila, the Philippines, on Monday, Dec. 19, 2016. The Philippines is considering regulations for digital currencies as the government seeks to bolster protection for the increasing number of overseas Filipinos using bitcoin and its counterparts to send money home. The volume of transactions involving digital currencies is "rising very quickly" because they offer a cheaper and quicker way to move cash than through regular remittance channels, Espenilla said.
