I think everything could be tokenised in the long run.
I even think with blockchain technology even tokenezing student cards is an option.
They should just use an address which is connected to the Gatcoin blockchain and that has special tags (like student or something)
I've heard Andreas Antonopoulos once say he can see a future, when kids in primary school create tokens them self that get value to trade kid stuff. Like marbles, or Pokemon cards also
had a trade function for kids. Interesting stuff to think about
For that to come true, either the process of creating tokens has to be simplified, or primary school kids need to become smarter. Although it currently takes just a few minutes to create an ERC20 token with some copy/paste magic.
