Bitcoin is superior to gold. Bitcoin's value is in its code. Facebook and twitter aren't tangible but no one questions their value. I think the problem is that people are focusing on the unit rather than what bitcoin allows users to do.
I disagree that Bitcoin is superior to gold, neither do I say Bitcoin is inferior (maybe close to Silver as an equivalent, hence the current price vs "the poor mans gold"
).
Bitcoin is to online transactions as gold is for storing physical wealth as an investment [or hedge if you can look past the propaganda in shows like 'Preppers' or whatever it is
] against currency instability.
They both have their uses that best suits the pro's and cons (sending Gold/Silver in the mail is much slower than sending Bitcoins for example) which is why I would not simplify the value between the two.
