Bitcoin may or may not be able to end poverty . Ending poverty is a very huge thing to do and all the people in this world do not have access to internet and the poor people don't have  any idea about whai is bitcoin. Bitcoin has become an investment asset.
The people who are using bitcoins are majorly the people who need to start their startups or are those who already wants to earn some money for themselves. So there is a very little chance that they will help to end poverty. They can only help by spreading awareness amongst more and more people about bitcoins who are in need of some financial stability.
