According to
world bank 1.7 billion people ranging from 200 million in China and India each, 100 million range in Pakistan and Indonesia, 45 to 65 million range in Mexico, Bangladesh, Nigeria etc. This shows that a lot of rural environments have no bank. Real estate, renting a building, is one strong marketing technique used by banks to garner customers in a place. And these stats proves that banks can't reach out to all rural environment. Bitcoin on the other hand, requires only a smart phone and internet connection to send and receive bitcoin anywhere in the world; no buildings needed. It also opens a portal for users in high corrupt countries, 68.9% of 180 countries, to keep their funds safe. In Sudan for instance, Government once forced into people's houses to seize and destroy their treasures.
Hence with 1.7 billion people staying unbanked, added to the increase of people who don't rely on banks, Bitcoin provides them with numerous options why they should use bitcoin for different purposes like sending money to relatives in different countries at a very low fee.

First, Bitcoin should be accepted as legal tender and companies start paying their employees in Bitcoin. Bitcoin should also be accepted pretty much everywhere too. Otherwise, I doubt this is going to work.
It is for sure a more complicated thing than just providing a means of banking for a lot of
the people who are classed as unbanked.
For those people who live on the equivalent of a few Dollars per week/month, having
the service of a bank is not needed, same for Bitcoin really.
If your life is revolves around the basics of food and shelter by the means of bartering or
very low amounts of FIAT I cant see how a bank is going to advance the lifestyle, same with
Bitcoin, how is it going to improve the lives of those?
