Can we let the comparison between Bitcoin and Gold rest? I've concluded that the two are useful, it depends on how we use them. We should however use them the way we know is best useful for us to make money and secure our investment. No one would trade/invest in Gold reasonably and lose, the same goes for Bitcoin, enough of this comparison, it's noise.
To me gold is more of fashion using it for beauty than bitcoin, when you talk about gold you remember your lovely clothes that is designed by Gold, your lovely necklace, ear ring name it all this is were we can classified gold mainly for beauty and design even though it is used as store of value or as a reserved fund.
And the price of Gold is not valuable despite having such a value you mentioned which Bitcoin can't do? After all, from what you said, it could be reasonably deduced that Gold has enormous use both online and offline, but what is the offline use of Bitcoin?
Bitcoin: when you hear about bitcoin what comes into your minds, investment, savings, peer-to-peer and mining. Apart from that what else comes into your mind?
When I hear about Gold also, it is investment, trading and values like saving etc that come to my mind, so what are you trying to prove? Come off it bro, both are valuable and can do almost the same thing, except for Bitcoin which can't function offline.
