bitcoin is just money, and like any other moneyz it can not do magical things on its ow. people can use it as a tool to make more moneyz an make themselves richer by increasing their net worth but to expect bitcoin to end world's poverty is just absurd in my opinion!
You are true, it cannot end the world's poverty. But i think it can bring some good to the world. It cannot end the total poverty. But if it is considered as a legal currency, then it could be possible to end the poverty in a very small amount. Full poverty cannot be removed. But, as bitcoin is growing its popularity day by day, then i think it will be able to do a tremendous change in world's economy as well as social development in future.
Hope for the best.
