For me proverty is not the problem of a person but of the whole nation in my country the eradication of poverty has becomes necessary for the sustainable and inclusive growth of the let state the fate here Bitcoin has helps the poor by Increasin their savings and access to capital also it has help around 1.7million people in my country and also it has also impoverished people to control their investment.
Bitcoin can have an effect into poverty but I doubt that it can completely eradicate it given the circumstances being faced by each country.
Remember that developed, developing, and underdeveloped countries have their respective economic and financial struggle that varies depending on their priorities. For example, underdeveloped countries have problems ranging from having no access to basic needs (e.g. clean water, food, infrastructures, etc.); while developing and developed countries may still struggle with having job opportunities, corruption, etc.
Sure, Bitcoin has significantly improve some of the lives of the investors but it being used as a tool to completely eradicate poverty? I doubt so- but it can definitely fix a dent on the economic struggle of some countries if they have laws that align with its interest for its people.
