Bitcoin could help poor countries obviously but it depends in what way. Maybe if we would all have the same currency then the 3rd world countries could get a little bit higher up and try to fix the country more but most countries 3rd world are corrupted though.

of course, bitcoin can help underdeveloped countries. with bitcoin then a country's population can work easier.
will be a lot of jobs available. and also will increase the outstanding economic.

Sure it could help, and one example is Brazil and Argentina. Many people don't feel confidence in their official currency, so they buy Bitcoins. And in a matter where you will have a inflation hate in the house of 12% in Brazil, Bitcoins had just 4%. So it was in Venezuela. Many Latam countries has this profile and people who are brave and who follow the world news (and it's the minority of people in this countries) got a bettet condition because they exchanged money long time ago, so they did the investment when their currency had some value. Many people reached the possibility of getting out of their hellish countries like Venezuela, and many don't lose a sack of money by the misgovernment and the disrupt in their local economies.

I think no, bitcoin can't help a poor countries.
But definitely you help a poor person through bitcoin.
Though bitcoin is being popular in the country but not
all people use to it. You can help a person by introducing
a bitcoin on how to earn in bitcoin. On how to earn profit
in bitcoin

No, you can send and receive bitcoins without internet using a 3rd party.

3rd party? Can you tell what is that? Bitcoin is useless without internet.

Even they can send this possibly without internet, how will they able to use it without an active data connection?

We have to accept the fact that bitcoin is only for online transaction, and since majority of the transaction in this world are not made online so it would not help the majority of people, the only people who will be benefited with this is those who regularly do online transactions, remittances could be a great help for the poor countries.

Yes or maybe buying a hardware wallet which has bitcoin loaded.

But like I said even that is possible, it's really useless since what is the use of having bitcoin if there's no internet around. Just to wait for price increase? Hmm not a good idea in my case since Im doing something to my coins whenever there is a large price movement increase.

Indeed I think it can help out a little bit too maybe by them using the currency the country would get more rich.
Or if they invest in it then they could make money like this also and then the country could be more developed.
