gold that has a very large inventory and is very easy to obtain so that the price of gold is defeated by the price of bitcoin and that is very likely to happen because you must be able to realize that the total supply of bitcoin is very limited
At present, the value of Bitcoin is huge compared to when it was created and it will be much higher than it is now. But to get Bitcoin out of gold, it's pretty hard because Bitcoin's numbers are so small, so Bitcoin's trading volume is hard to beat.
bitcoin is more easier to obtain imo because you can just mine it or buy it and there are also many methods to obtain it like for example working online thru forum ( e.g sig campaigns , bounties , airdrops , faucets , etc )
while gold cannot be easily buy and it is also rare to find a seller that sells an actual gold chunks . gold is also minable but it is hard to mine a gold these days because there are now a lot of miners . mining a gold do also require a special equipment not unlike to mining a btc which you can use several devices .
