Money has a very distinctive smell. A really good smell. "The smell of money" - even sounds cool.
Bitcoin doesn't smell like anything. Totally sterile. That sucks. This is what I see as the major flaw of Bitcoin.
But you forget, bitcoin also lacks stripper juice, booger, pizza stains, and any number of other nasty things that can typically be found on your favorite fiat. I guess there is a trade off to be considered.
