> At the very least the definition of currency ought to change to something like: "A currency possesses at least 3 out of 5 of these qualities. Actually, if you look at the definition of "currency" from various sources, you'll come across stuff like this: "1. Money in any form when in actual use as a medium of exchange, especially circulating paper money." (http://www.thefreedictionary.com/currency http://www.thefreedictionary.com/currency) ... and for "money": "1. A medium that can be exchanged for goods and services and is used as a measure of their values on the market, including among its forms a commodity such as gold, an officially issued coin or note, or a deposit in a checking account or other readily liquefiable account." (http://www.thefreedictionary.com/Money http://www.thefreedictionary.com/Money) The problem doesn't seem to be that the definition is incorrect; the problem seems to be that people assume their own definition based on what they're used to, rather than adhering to something you'd find in a dictionary - commonly the motivation appears to be using "it's not a currency" as a (fallacious) reason to express their dislike of something like Bitcoin.
