if they have the account, and whether paypal apply there?
They do have paypal; I know local charities which accept donations via paypal. So BTC's the logical next step.
More than that, this creates a totally new situation. Here, in our rich countries, we wonder how we could integrate BTC in our daily life, but to Somalis abroad, BTC may be the only option to send money home. I'm using BTC because there wasn't any other choice. Hey, that's cool.
