yes, i think bitcoin can help some poor countries
we can sent it to their delegation and they can exchange it to their countries currency then distribute it to all inhabitant
or they can hold it for future plans
why would we send bitcoins? we could also send money as in fiat money. and nobody does that. so why should we do it, just because we use bitcoin? also the number of money/fiat/bitcoin we would neeed to send to make a difference would be huge. to huge i think.
