Separatists in Cameroon's English-speaking regions have launched their own crypto-currency called "AmbaCoin", according to the Quartz Africa news site.

They want to create a breakaway state called Ambazonia, and this currency is the latest symbol of nationhood that rebels have attempted to adopt, along with their blue-and-white flag and anthem.

One AmbaCoin sells for $0.25 cents (£0.18), reports Quartz, and is currently on pre-sale ahead of the "main initial coin offering scheduled for 24 December".

Quartz adds that the AmbaCoin was "conceived and built by a group of anonymous Anglophone separatist scholars, technocrats and developers".

Cameroon's official currency is the Central African franc (CFA), which is linked to France’s national treasury. There have been calls from some to scrap the CFA, which they regard as a "colonial currency".
