Even pre-teens and teens use paper currencies around the world on a daily basis, but hell they can't even purchase Bitcoin without being 18+ yrs old and having a drivers license and a bank account first. How about that fkn irony, Satoshi? Should we add an addendum in the white paper for that too?
There is localbitcoins for that. Just putting that out there.
There are teenagers in places other than the USA where those rules dont apply.
