First of all, I would like to show you similarities between Bitcoin and gold.
The value of both are driven by both scarcity and demand.
The both are decentralized, and the both have limited supplies, the list goes on...

But despite this similarities they still have their differences, Bitcoin is easily transferable while Gold isn't .
In Bitcoin transaction is transparent, but with Gold authenticity can be disputed etc.

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.
Bitcoin and gold  share similarities as store of value,and hedges against inflation.
However the differ in transfer speed, portability, security and transfer speed.
If investing, investor should consider their individual financial goals, risk tolerance and market understanding.
