Bitcoin and gold share the same purpose. They are both hedges against global insecurity, economic instability, and inflation. Both assets are intended to provide security for investments. However, GOLD is a physical asset that has many intended uses, which makes it a highly sought after resource while
BTC still a virtual one which sometimes crypto traders used to trade at a particular exchange
Gold is more of Great Depression type of hedge but bitcoin is just a general unrest in the economy and I do not think that they share the same purpose. Bitcoin does not provide security like gold, remember that gold is still the chosen reserve by countries even though bitcoin is a far better option for security.
As far as I know from bitcoin and gold, there is no relation whatsoever, gold will not be able to influence bitcoin price movements and vice versa bitcoin will not be able to influence gold price movements, but if you want to get a lot of profit then you can buy bitcoin and use bitcoin as much as you can, bitcoin will provide a lot of profit because of the influence of limited supply and very high demand.
What you know so far is right, bitcoin does not have any relation to gold. For me, the only relation that gold and bitcoin has is that people keep insisting that they have a relation, don't they know that there will be chances that the prices of both market goes down the same way, well if we will go that far, I think bitcoin, stock market, gold and airplanes have a relation, and that is all of them goes up and down.
