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.
If this is in Indonesia, this may not happen, moreover people need bank account to have transaction or everything about Bitcoin activities. So, having Bitcoin means having bank account, commonly like this.
What happens to the society is that people are still using very traditional concepts' of transaction or payment, moreover in the traditionally market. Some also are still not using any bank because they are lack of the knowledge or they are against bank and prefer to save their money in gold or others. Moreover here, Bitcoin is not legal if used as payment method and I ma very sure that people who are not using bank account are also not interested in Bitcoin.
But, don't know if it's in other countries as mentioned.
