ugabda should develop their own coin and built it on the blockchain if they think that bitcoin is too risky to be adopted into their economic? The infect of USA dollars on most of Africa's currencies is too high and it will be very difficult for some of this country to develop. To me, Bitcoin is too volatile to be used as country money and if Uganda does that it will create serious problems in the country but on a long run, they should develop their own coins just as companies like Facebook are planning.
They could just make another stablecoin with their own currency or backed up by something else valuable if they want, but what is the point? in Uganda internet is not available everywhere, I don't live there so I don't know but Uganda is not a developed country so that is to be expected, digital currencies there will just available for certain people and not for the masses.
