only feature that has worked successfully for bitcoin in past 15 yrs is STORE-OF-VALUE vs any asset priced in fiat provided it can be spend directly without ramping or kyc in certain jurisdictions only. 

 Cash, cache, a place to *store* valuable things.  Cash isn't meant to *lose* value.  Bitcoin puts things back in order.

It's a bonus that bitcoin also works P2P over a wire like fiat monopoly credits.
