Re: Gold
"If other people essentially start "minting coin", this takes one of the main sources of power out of the government"
That part isn't true. The BoE is independent precisely because we don't want to give politicians that power.
Other than that you're right, Bitcoin is a scam and the claims made about it are not only untrue, but obviously untrue. It isn't private, it isn't secure, it isn't usable as money, etc etc.
