In terms of investment, it is possible that Bitcoin can replace gold, but in terms of the function of Bitcoin it cannot replace gold. Why, Gold is a real item that we can form in various models, while Bitcoin is a digital item that only we can find on the internet. these are two very different things. If for gold and Bitcoin investments can be invested together, even Bitcoin has better potential.
Exactly, they are totally different form of investments. No matter what era or age we are, physical gold will always be here. But bitcoin is something that we can't have a physical grasp. I guess bitcoin can never replace the benefits of gold investments.
