I do not consider gold to be money. You can't go and buy most goods and services with gold. Gold is a commodity, dollars are money. Bitcoin is a virtual currency. It has more in common with paypal than it does with dollars or with gold. I wouldn't really call it money until it is more widely accepted as payment for goods and services.
it doesn't make sense what you say, bitcoin have nothing to do with paypal, paypal is a trusted tthird party that function as an escrow basically, bitcoin is an untrusted payment system
if you want an example how it would look to have paypal in the bitcoin world, bitcoin is the money paypal is the escrow, bitcoin is no different than electronic cash, i would compare to that, "virtual curreny" is just that...
