Well in most developing countries of the world especially in Africa and southern America the battle of a stable currency has been there issue and this countries has sometime serious of inflation and there currency are so weaker can only be accepted for trade within their country.
If bitcoin becomes adopted generally if will Forster a healthy trading ecosystem among countries and also tackle problems of inflation, slow and ineffective transaction processes and even prevent scam and corrupt practices
I beg to disagree. They're still going to need their local fiat and bitcoin won't be the solution for their economic problems. Sure they can go trade within their country, but what if they go outside? Bitcoin is not yet globally adopted so there's a lot of adjustments. Bitcoin though can be a good tool to fight inflation but its not the go to "guy" to salvage their economy if that's what you are trying to drive at.
