> You don’t want your actual currency to gain value just by waiting.

Relative to what? Talk of BTC gaining value is primarily wrt USD; I'd be perfectly happy with my actual currency (GBP) gaining value wrt USD.

I suppose BTC can only 'deflate' in the long-run (and with an assumed supply of goods and services available in exchange for it) since the mintable volume is fixed. But perhaps it exposes that talking of currencies inflating is a bit sloppy, as it doesn't really make sense for BTC, and it's the economy or banking system that inflates really..
