Such comparisons are meaningless, by and large
Since only a small part of both assets is being actively traded. And to make any reliable assessments, we should look at figures showing actually traded amounts, not total reserves. Regardless, it looks like only a tiny fraction of gold is present in the gold markets at any specific moment, so the genuine value of Bitcoin could in fact be way higher than the measly 1% of gold value. Apart from that, we should also remember that unlike Bitcoin (which is always present in "person", so to speak), there is plenty of paper gold which severely affects the gold price (and likely in both directions)
