Addressing the future, cryptocurrency such as bitcoin should be taught in schools. This is why I did innovate a basic strategy as my research to used base numbers in cryptographic algorithm.

This is a very good issue you raised. The bitcoin and blockchain are new innovations that'll sharpen the world in many ways.
I believe we should start teaching the basics in primary schools, high schools and colleges. The training should be on the technology and financial sides of the evolutions.
Knowledge is power but the application of knowledge is powerful....
