Poor nations can benefit from Bitcoin if they invest in it. Countries like El Salvador and Bhutan have invested massively in Bitcoin and I guess that they are now in profit. Bitcoin could also help nations and business owners to avoid the exuberant fees paid to middleman during international trade. Beside these two benefits I don't know if Bitcoin can reduce poverty in a nation. People from poor countries are more interested to survive, hence many of them might not consider Bitcoin investment.

Internet facilities are very expensive. I don't know how Bitcoin will help people from poor nations to develop internet facilities. Maybe they can join financial resources together and buy a satellite connection maybe from Starlink.

The "if been ligalise" thing in your text makes me laugh. Do you mean "if been legalized" or you mean something else?
Are you coming up with the assumption that blockchain technology and Bitcoin are banned in poor countries? I don't have any info about this and I think that blockchain technology isn't banned in the poor countries. Nobody is stopping the people from using crypto and blockchain technology. The problem is that the people, who are living in poor countries don't have money to buy crypto. Blockchain projects require skilled programmers and capital. Poor countries don't have good education systems and skilled workforce.

Microfinance platforms based on blockchain could also open up new opportunities for entrepreneurs who might struggle to access credit otherwise. Plus, the lower costs of remittances would be a huge advantage for families relying on money sent from abroad. Many people in those areas have smartphones, so being able to use Bitcoin for payments could really help ease transactions. Improving internet infrastructure for these people through these projects could also have a ripple effect in enhancing the overall connectivity and access to information. This is quite an exciting prospect

Lots of opportunities, but mostly, it would come from better management of all the other systems - surely, what you described would help people and would do so a lot, but, it should be built upon a proper investment base the ability to create and sustain such big and tech-strong projects, and so on.
To keep things the way they are developing.

A country should start from the bottom - sure, the reserves of the BTC and other related to Bitcoin or crypto projects are great and should be encouraged developed, however, first, there should be a solid base to do so.
That would, by its nature, provide everything that's needed for such projects. Because they won't fix the things you mentioned, I agree with that.

I do think they would be in good shape to go into crypto (said countries) once they are on the right track everywhere else.
These techs and so on won't help them to get rid of the problems they already have. Sure, some people would have more opportunities to use the blockchain, and so on, but the standard of living would still not go up.

Any country that wants to elevate themselves from poor to a standard developed country should first look into so many things going on inside, if they are poor as said, how are they supposed to work the resources to be used for investment purpose. The country needs to be relevant from its sources, economically fit and a well balanced resources to see them through the process of investment. Just like what the US government is trying to initiate, reserves like that for a poor country can help them but it needs to be in the long run, if they are unable to create a favorable economy up until the reserves are matured for sell it will cause them to tamper the long term initiative.

I end up saying, Bitcoin can help poor countries get to a standard financial economic condition but won't be the sole achievement to pull them from poverty, start domestically and close the chapter by making reserves that will surface later to stabilize the economy the more.

Honestly, I am sure that it has helped them a bit, because their investment grew, they got in at a lower price, now have more money, that's a benefit isn't it? Secondly, it "can" create jobs, depending on which nation we are talking about. Of course El Salvador wasn't seen as prime location, but if it was, every big crypto company would open their headquarters there, and hire people to work there instead.

But, El Salvador wasn't big enough or good enough to attract companies like that. At the end of the day, if USA makes it legal tender one day, which isn't impossible if you ask me, could happen in the future, then we could see a lot more stuff changing and then it could help a lot of people without a doubt.

Making an investment in Bitcoin is one of the ways they could seize the opportunity in it to change their own economy for good, but before that, there must be some instrumentation laid on ground for the fair policy on how to go about it, this will help them devise a means to invest, the strategy to use and the duration the investment will go for, when there is adequate planning on ground made already, things will work out for them, but before then, they have to have a concession on how to start.

Only Bitcoin cannot turn the fortune of a country. The nation has to put in place necessary economic policies that will improve living standards, improve infrastructure, and attract investors. El Salvador has a good plan for its Bitcoin investment, which is why they have been hodling it for a long time. An example of a country that failed to plan before adopting Bitcoin as a legal tender is the Central African Republic. Lack of planning was the reason why the country's Bitcoin experiment failed.
