Digital currencies are a terrible concept and I was always against it, it's basically the opposite of decentralization due to the exchanges & the complexity of the subject rendering most users at the mercy of a few in the know. On top of that, in practice, digital currencies are used for the worst things humanity has to offer! But one can hope that young people will learn useful concepts from pursuing the subject.
edit: I'm also wondering, why don't they offer a true javascript shell instead of a fake one? When asked to run the `echo $sig | xxd -r -p` command. The benefit would be that the user can experiment some more with the command line.

Of course speculators, i.e. the vast majority of bitcoin users, want issuance to stop at 21M, to keep playing their game of number go up. As long as the potential problems of fee dominated mining revenue is decades away, they don't care about them.
