Feel free to redefine "sound money" to take into account bitcoin.

Redefine it from what?

But honestly, I don't hear the phrase "sound money" that much, where do you keep hearing it?

Really? Do you only read mainstream media finance articles?

The phrase is used a lot in the Daily Reckoning for example:

Redefine it from whatever definition you don't like.

I don't read dailyreckoning.com, sorry, never heard of it.
