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.
However, the computer is there to compute the numbers. But still, learners should be able to know the manual computation and how it increase and decrease according to its equivalent value.
In addition, this will make the new evolution of numbers of Mathematics.
There's been this big news that France included cryptocurrencies and blockchain into the official school curriculum. There won't be a whole subject dedicated to it, of course, but there will be some lessons as a part of Economics (and perhaps Computer Science, I am not sure). Moreover, some universities offer courses in crypto and blockchain. Just recently I found about a couple of them in my country (one listed in an online profile, another mentioned by a person who claims to know the guy to teaches it). So while slowly, Bitcoin starts to get attention from the educational system, which is definitely a good and necessary thing.
