The May Scale of Money Hardness and BitCoinhttp://stakeventures.com/articles/2012/03/07/the-may-scale-of-money-hardness-and-bitcoin
This tickles me.
When talking about Bitcoin with people who are unfamiliar with it, the obvious comparisons to other digital currencies and value transfer systems come up.
It may seem like a minor point of terminology - but to refer to bitcoin as a 'hard' money due to it being irreversable and unconfiscable versus 'soft' molestable systems like Paypal is a good way of emphasizing the distinction.
People understand the 'hardness' of cash - so it makes sense to apply it to bitcoin in this sense.
Perhaps this little bit of spin terminology has come up before - but it escaped me!
edit: indeed, when I search for 'hard money' and bitcoin it does come up. Well - it seems like a meme worth spreading.
As pointed out by someone in the comments of the article, 'hardness' is already ranked against various payment methods on the bitcoin wiki: https://en.bitcoin.it/wiki/Payment_methods
