This is one of the projects the world needs.People in developing countries need to have access to a sort of banking system.Millions of people need this and if this project is transparent and honest it can make a big difference for them. The project can grow in the future and become large.
In General, this will probably be a trend in the future. And perhaps the rest of the world's leading banks will also switch to a system using blockchain technology.
A higher possibility that it can be adopted while in sone banks they are now researching for using blockchain technology to out on their system. The one that i heard is union bank if I'm correct. This systems will be soon replace by faster technology and transparent to all people by which not providing the personal information of a bank user.
Humaniq is ahead of it in my opinion they are the best fully blockchain system who's working on this matter as of now.
