Worldwide, approximately 2.5 billion people lack a formal account at a financial institution. Access to affordable financial services is linked to overcoming poverty, reducing income disparities, and increasing economic growth.
Sorry, but this is blatant propaganda of the established banking industry. "Linked to" must be interpreted as being based on correlational data. So the true relationship between the variables mentioned is most likely not that access to financial services leads to overcoming poverty. Instead it is merely the observation that people with a higher income are more likely to use financial services as well. It is complete nonsense to assume that giving bank accounts to poor people will make them rich.
You're right with your assessment, that for Bitcoin to become successful, people must be able to buy their daily necessities with it. That is the true mission that needs to be accomplished by the actors of the Bitcoin economy: Providing
essential goods and services (food & shelter). If people in developing countries could use Bitcoin directly to buy their necessities, no remittance service would be able to compete with Bitcoin anymore.
ya.ya.yo!
