a great development, and very helpful for the people of Zimbabwe and this can raise the price of Bitcoin itself.
but maybe for inflation it is difficult to control, because Bitcoin can only be a medium of exchange, but hopefully in the future Zimbabwean state can stand upright like before.
I doubt that one bitcoin ATM can affect the price, but Its sure a good news when bitcoin is spreading on all continents. Africa is very populated continent, they have a lot of resources if they manage to combine blockchain and their resources they can escape from poverty.
Africa can be one of the leading forces od blockchain in the future, they have man power, they have resources, they have so many deserts where they can build renewable sources of energy, they can build miners. If they manage to organize all that then they will push the price of bitcoin very high. But only if they agree and do something all together, whole continent, only like that they can affect blockchain on larger scales.
