I guess they have a crappy currency, even crappier than currencies like the dollar or the euro, and people get by as best they can. Apart from being extremely useful for the unbanked. That makes sense. From what I see on the forum, something similar is happening in Nigeria.
It's really a good project development.
However the risk includes.
Volatility:this means that Bitcoin value can change fast which make it uncertain.
Security risk:means they can hack your Bitcoin wallets
Regulatory uncertainty:when Bitcoin laws and regulations in that nation are been change it can affect the use and the value.
Loss and access: when someone forget his password or his private keys it can lead to losing his Bitcoin.
These risks I mentioned are the important of caution before engaging on Bitcoin.
