Only can applied for a developed country but can't applied in poor countries.

How those people in the poor country will get their life improved if by any means they didn't have a chance to access any bitcoin related works? Fiat currency can't help them in some of the matters so how much more in bitcoin.

yes definitely bitcoin could help poor country but they should be brave enough, if the country is brave then they might become victim of scammers and thieves. by trading with bitcoin they could definitely make huge money and bitcoin will help small country because it will have less population and so their economy would rise up.

on the other hand it has the potential to destroy many jobs. people involved in traditional financing. if bitcoin changes the world then banks and people working for them will lose jobs.

the main thing is that people expect too much from bitcoin. they think it can directly solve this and that problem, while in fact it can never be solved with the governments being corrupt. that aside, poor people will not put their money into something that they might have no access to. think at them not having internet, no smartphone, etc. it's not as easy as it may seem. these people have other things to worry about.

Creating jobs is one thing and financial stability is another thing. The revenue the company earns should be enough to supply the employees and the future development. That is more easier done on fiat simply because it is accepted everywhere. Its difficult for bitcoin to take that position but it can happen if and only if the governments start to adopt it properly.

i do believe most government around the world wouldn't adopt bitcoin in their economy and banking system. as most of them just think about how bad side bitcoin used out there and then they playing with the media , spread false things. hard to cooperate with them , so nothing so much bitcoin can do to help poor countries developing at least for now.

But the jobs bitcoin hasnt created are limited and wont be able to help all the people from the poor countries at all, sure some people may find at signature or at bitcoin a safe way to survive, then the real job offers they might get there. Besides that they will need to exchange and trust into someone outside their country since its hard to believe someone with money will echange bitcoin into fiat.

Yes, a country is nothing but its citizens. Innovating new business for bitcoin ecosystem will help any countryman could bring new lifestyle to his folks.
I too do see, lot of opportunities to innovate new business based on bitcoin system that may result in supporting many lives. Other than this, simple freelancing way of earning will definitely help any poor country citizen.

When a country is suffering due to its economical collapse, instead of going with USD or gold, may prefer to go with bitcoin payment system as their reserve money that will help in many ways like we have seen and discussed when Greece had similar collapse and situations.
