Yes I can say that with confidence the bitcoin is gonna do this, I think the first country it will help is Brazil because they already have a lot of accepted stored right now.
There is indeed a chance it will change a lot of poor countries in a better place by boosting their economy with the bitcoin.
Brazil is going to the right direction so I also agree about that.
Brazil is a BIG country, continental size, if you try to find any place that accept bitcoin there, you will waste your time, because the nearest place can be a 50 miles away, so isn't "a lot" of stores...
