REASONSNotice the weasel words, 'what some consider'. Bitcoin.org should not assert that Bitcoin or bitcoins are a currency. 'Currency' is a legal term of art and like the word 'funds' can invoke some nasty sections of law. Currently, Bitcoin and bitcoins are clearly neither 'currency' nor 'funds' under applicable statutes, like
31 USC 5103, because the standard to be 'currency' and 'funds' is usually that is must be legal tender.
I don't see any legal definition of currency, only United States currency. Bitcoin is obviously a currency.
