In Johannesburg, South Africa, Lorien Gamaroff believes he has a way for Africa's millions of unbanked consumers to pay their utility bills - the digital currency Bitcoin.
Gamaroff worked as technical director at Invirohub, a smart meter developer owned by the Bidvest Group, before founding Bankymoon
Gamaroff, a South Africa national and founder of Bitcoin company Bankymoon, has a background in developing software applications for smart meter solutions.
Gamaroff said he "looked under the hood" of Bitcoin and liked what he saw.
Launched in 2009, Bitcoin is a decentralised currency that is independent of central banks and governments.
Users download a Bitcoin wallet app to their phone or desktop to top up their own meter or members of their family's in another country.
