Following are a few comparisons I have thought out, for the reason I am invested in Bitcoin..
Transferable
Bitcoin’s can be sent peer to peer without the need for an intermediary or multiple intermediaries. Bitcoin is also highly divisible making the smallest transfer, as economic as the larger transfers
Gold would need to be delivered by post, or change of ownership on a deposit account. Gold is not divisible, apart from a costly process of melting down the Gold which results in losses or mass.
Limited Supply!!!
Bitcoin - has a transparent supply, which is decreasing overtime at a predefined rate. Current Supply is just over 15.6m to it will cap out at 21m. Inflation last year was 9.3%, this year is 6.4% and next year 4%.
Gold - is very un-transparent. We don’t know with a level of certainty how much has been mined, how much hasn’t been mined, how much (in the future) is mineable in space.. Interestingly, Bitcoin also annihilates all national currencies in this category. Bitcoin over a long enough time horizon by this metric alone can only go up in value..
Divisible Cost
Bitcoin - costs the same whether you buy $1 or $10,000
Gold - costs far more per gram the less you buy. Just see (https://www.bullionbypost.co.uk/gold-bars/). This is the main problem that DIGIX are trying to solve.
Transaction Cost
Bitcoin - cost of transaction is negligible
Gold - cost of transaction can be very high when your paying for insured delivery and brokers.
Costs of Storage
Bitcoin - Free
Gold - Either the cost of servicing a vault or paying insurance to protect yourself at home
Access
Bitcoin - You can access you Bitcoin wherever you are in world
Gold - Access is only to where it is physically deposited
It an interesting case when you go through comparisons between Bitcoin and Gold is how many categories Bitcoin wins out. Now Gold does have some uses in the real world like Jewellery and Electrical cables, however the Jewellery case comes in and out of Fashion and it’s too expensive to make economic sense in electrical cables. Value is set in supply and demand. The way I see it with Bitcoin is, supply has a natural cap, so if you feel that demand will rise over the coming years, it makes a pretty strong investment case for Bitcoin, especially when compared to Gold and National Currency for that matter.
