if you have no money at all, then you are to poor to buy bitcoins. but other than that you can exchange your local currency for bitcoin for very small fees. in fact they are so small that you could earn them with some faucets or signature campaign.
sometimes i get the impression that people, that talk about bitcoin being to expensive, think you have to buy 1 bitcoin, like it would be not possible to buy 0.5 bitcoin.

Bitcoin is invention. Which can give better economy as well as transparency in financial transaction. Due to some innovative features like as Anonymous, instant, open source, transparent can give more better solutions which can reduce poority.

But if we consider formulation of Bitcoin, which need lots of computing power.

And poor country may cannot afford this much power cost to make sustainable environment for better digital and virtual economy which is based on cryptocurrency.

But Bitcoin can give opportunity to enhance better economy in poor country.

Long Live Bitcoin.

This thing is  one of the benefits  of bitcoin which we could really do peer to peer transaction without any hassle of having a bank account as you said. I do agree with you that it could easily spread directly to the people. This way would somehow help  on poor countries.

bitcoin is not mother thresa to help poor countries, bitcoin is just another currency like any other with some extra features.

it is up to the people of those countries to start thinking for themselves and earn money, but yes if they can start earning bitcoin online that would be a great help for them financially.

yes it is a fact that poor people cannot afford bitcoin to buy, as the currency of some countries is very low as compare to USD, just line india and pakistan whos currency is too low as compare to bitcoin but still we can see people from these countries to invest money in bitcoin, but i think they will be feel it to difficult to invest because their currency is too low as compare to USD.

Buying is not always important but people can also earn them as that is what me and a lot of people are doing in this forum, buying is for those who can afford it but not for those who cannot.

Bitcoin is probably a currency like others but earning it online is way easier than other currencies i guess so if the people in poor countries come to know about this so they can get good financial help as you mentioned, i have seen a person who said his monthly salary is $80 and he runs his family with that money so you can imagine what bitcoin can do for people like him.

That's sad! And they will stay poor without electricity...

At least the world have projects to help they in this point, solar plants and thing like that, hope they can "fix" it soon!

I think the country agrees that the poor have a lot of problems. not only financially but mentally, politics and so forth, but it is at least bitcoin might help the private economy of mass

If bitcoin was adopted fully then it could help citizens of poor country. These people usually don't have bank account, so direct p2p payments system like bitcoin should be good option for them.
Unfortunately Bitcoin in its current state is not capable of influencing any country poor or wealthy alike.
