The fact Bitcoin is volatile and gold is more stable , and the fact that gold has high liquidity and Bitcoin is still growing, makes investments consideration quite tough.
None is stable between them both. Gold is less volatile. Gold Bitcoin is also having high liquiditt. Just that gold has higher marketcap and also can be more liquid but if you want to buy millions of bitcoin, you will be be able to buy it right away. I prefer bitcoin investing after a significant bear market but it is good to diversify.
This question has been asked here too many times and it doesn't make sense to ask on Bitcoin forum which is a better investment because people here will naturally be biased towards Bitcoin.
To ask this question you would need to find neutral forum for investments.
Not that they are biased. Bitcoin is giving higher ROI.
