Nahh I can't believe bitcoin can do that!
Bitcoin is not a magic. it's money just as your fiat but digital and a significant difference is that instead of depreciating years after years it increases or appreciates in value.
For a poor country to become more developed they must fix their government first bitcoin is not a saviour to come and elevate poor countries to riches or high economic power however if a good government is in position their can grasp the opportunity to invest in it and help their economy from what they get from it.
Bitcoin can make transactions faster and easier and also low cost of remittance in poor countries, if been ligalise.
Can the poor people from poor countries afford the transaction fees of bitcoin for a transaction?
