Here are some possible reasons why the above African countries are better off putting their money in bitcoin:
The Sudanese Pound has suffered from U.S. sanctions and secession of South Sudan, which has resulted in the loss of most of its oil and foreign exchange resources
The Zambian Kwacha has lost its purchasing power due to inflation as the country’s mounting debt burden has resulted in the country defaulting on its loans
The Angolan Kwanza has depreciated by over 17% in 2020 against the US. Dollar brought on by the fall in foreign currency resources as a result of a drop in oil export revenue
A recent report by Luno seems to support the above conclusions. The report shows the rapid adoption of cryptocurrencies is more likely in Africa in the context of high inflation rates, volatile currencies, and underdeveloped banking infrastructure.
Bitcoin is currently at an all-time high for the year 2020 having already gone up by over 70% this year alone.
