Pretty much all types of currencies have that phenomena (as a store of value function)... I'm just trying to point out that there are two types of hoarding: "hoarding by money users" and "hoarding by central banks" (the issuers of that money). The former serves as a confirmation that a store of value function is present and working well within a currency, the latter destroys all three functions of money. Now, you seem to be in favor of the latter... What gives?
