Sorry - when referring to encryption, i didn't mean encryption surrounding coins.

So - when sending funds and receiving coins from mtGox, it's essentially a person(s) doing this.  This is what I'm referring to.  I think for the 'average joe' to accept this (assuming they even check) would take a whole perception shift.  PayPal is PayPal.  People know PayPal and "trust" PayPal.  What's the driving factor here?  I'm in to BitCoin because it avoids major institutions?  Because there are lower fees?  Why do I decide to start using BitCoins (hypothetically speaking of course).
