Indeed.  This is why we are here isn't it?

I loaned a friend a few bucks for a poker game recently.  From my wallet to his hand.   I busted out, but he cashed.  He paid me a portion of his winnings.  From his hand to my wallet.

The only people who know about this transaction are those I chose to tell.  And there is pretty much no way to confirm or deny my experience.  You take it on good faith that my story is true or you assume I made it up. 

This is one way money has been transacted for millennia.

Bitcoin brings speed and verifiable transparency to commerce.  <- Valuable!

Monero inherits that speed but allows for the privacy we are accustomed to for cash transactions.  <- also valuable!
