I think the first thing would be for the rich countries to use their power and influence in exposing and helping to bring to book all those rulers from the poor countries, that have stacked their stolen wealth overseas. It stands to reason that, the plundering would have been minimal without the corporation of the rich countries. Just like IMF and World Bank, compels and monitor governments of some countries to implement their agreements, these things are possible if they put their legs down.

Leaving the poor countries to their fate and hoping someday, change would come is an illusion and takes the world further back to the stone age. What is the United Nations really all about in the first place - to mediate in wars that could have been avoided? Bitcoin is a pointer to probity and accountability and could check lots of loopholes those rouges use to siphon their country's wealth.

India is the best example right now for this thread. A lot of people got their gold and money seized because they had no proof of where the money comes from. Bitcoin might help some because they can buy Bitcoin with the money they own, but what will they do with it after that..? I guess they will ban Bitcoin too, I mean now you're not allowed there to own gold, you're not allowed to own old money, the new bank notes.. I guess over half of the population is now poor. Bitcoin cannot help a country in which the technology isn't even advanced enough and not many people can afford paying their electricity bills.

Why do most people here assume that one needs a PC to use bitcoin?

I'm using bitcoin, making all transactions and work using my smartphone (except mining, obviously). I'm just using PC for some bitcoin related jobs like CoinTasker, writing on Bitcointalk.org or Trading. And Believe me, a lot of poor people in my country are buying Smartphones to surf the internet and discover the world of technology (Although, they don't even have something to eat!). So, in my opinion, I think they only lack the knowledge of knowing what bitcoin is.

When it comes to bitcoin reputation in my country, I can say that it's living in oblivion (something that I'm really grateful for, at the moment because our government is bloody stupid). So you are right. Even if the poor obtained the knowledge and basic requirements of bitcoin, they won't be able to spend it.

India is generally one of the richest countries, despite the low standard of living and high poverty threshold. Just the number of rich people there are not small. But only a big business, and bitcoin can make the country and, most importantly its people live with prosperity.

Can Bitcoin or any other altcoin help poor countries?
how? what can be done?

If we want to help poor countries is easy, but with bitcoin is make easier. The big problem is not the countries maybe not accepted bitcoin.

I think millions of people in India use the Internet but they are still poor. So for those people Bitcoin for sure can be helpful.

And actually if to talk about those whose gold and money seized because they had no proof of where the money came from, I don't think those people are poor. Poor people don't have gold and lots of money about which they can't explain from where that came from.

Governments working on trying to decrease poverty is what they want you to believe, while in reality the opposite is happening. Poverty is a great tool for the governments to put a major group of people in one place where they can use them for whatever purpose at barely any cost. Without poverty, India isn't able to compete with other countries as multinationals can get things done for peanuts and sell it in wealthy countries with massive profits. That's how it works. If the government is really trying (big scale) to work on poverty, then it directly will also harm the government there as these multinationals simply move to another country with their business.
