Cryptocurrencies might be enduring tech rave of the moment—but not for Zambia’s apex bank.

The central bank has warned against using cryptocurrencies like bitcoin as they are not recognized by the country’s financial system. As such, trading in or using cryptocurrencies, it says, will be at users’ risk as there is no legal recourse with all cryptocurrencies still unregulated in Zambia.

Nigeria and Kenya, two of the continent’s largest economies, have gone from warning banks against trading or doing business in cryptocurrencies and comparing them to pyramid schemes to reportedly researching policy proposals and studying benefits of cryptocurrencies’ underlying blockchain technology.
