Yes, it's possible because bitcoin does have a positive impact on our economy, especially for the poor, but the bad impact is that money laundering is very easy, it will harm the country.
I think if bitcoin is received in every country it's a very good thing, and I believe that bitcoin, in particular, can reduce poverty when many people invest in bitcoin. But that can all happen if every country receives bitcoin.
Reduction of poverty will only be to some certain extent and that would totally depend on how people are ready to accept its usage or not. One fact is not everyone will but at least for those who will and ends up reaping a good benefit from the space, it would be an easy thing for them to grow economically, maybe over time create more jobs as the case may be, and would therefore be able to affect those who might not be a part of the community for reasons best known to them.
