If bitcoin and gold are both presented before me and I am asked to choose only one, I would happily choose bitcoin any day and any time.
And if for example, I am blindfolded and asked to choose on a piece of paper, bitcoin or gold, and I mistakenly choose gold, I will be very angry with my self for making such a mistake..

I am not saying that Bitcoin will replace gold because in as much as bitcoin is doing better than gold at the moment, gold still have some really important uses in the world most especially in the fashion industry, so golds existence can never be over emphasized, but gold and bitcoin can peacefully co-exist together, the physical gold can serve the utility it provided in the world or fashion while bitcoin being the digital form of gold can serve well in the world of investment.
