A fool and his money...
That's quantities of money; this is actual currency. Different.
How different? The majority of money is numbers in a ledger (which has been electronic for the last 40+ years), cash is only a fraction of all money that exists: MB + M0 - M3 + MZM).

Value is more likely to be preserved if a currency has :
(1) Reliable ledgers.
(2) An entire nation / economy of workers who are contractually paid with that currency. (Who is obliged to accept bitcoin?)
(3) The issue of new currency (lending) is restricted to new assets that devalue slowly (not worthless used computer processing).
(4) New currency can be created according to demand. If supply of a currency is artificially restricted (like Bitcoin) or is tied to a rare asset (like gold), this can restrict lending and economic growth, causing people to switch to alternatives.
