Bitcoin can not eradicate poverty around the world. Even if it is not bitkoin and another currency The whole world has always been divided into rich and poor. Dengi is not the goal. A goal is a person's needs. If a person sets a goal to get education to open and develop his business. This person will be rich. And if, for example, a drug addict or alcoholic also needs money. But their goal is different. Therefore, such people will never be rich.
I think the same in this matter. Poverty is a very big problem and Bitcoin alone cannot handle this. It is far more than its potential. Even if we combine all the crypto currencies of the world still we cannot manage to get rid of this problem.
However the effect of Bitcoin on the financial status of the holder is very clear. Like you said it is capable of improving the individuals economy in a dramatic way.
