The potential that you are talking about could always go south. I dont think that bitcoin has the potential to win over gold. It does has the potential to stand on the same height as gold however to win over gold that has stand as strong as of now for thousand of years would be near to impossible
It is just a matter on how the majority has seen this bitcoin even if it is just an internet money but if they see this as a sign of freedom that they can use bitcoin to transact in a decentralized system they will treat this one as a gold.
gold being here for thousands of years doesn't mean it's more precious than bitcoin. and in fact it isn't as gold basically has an unlimited supply that will come above ground in the coming years and the hundreds of years after that. another important thing is that the current gold stash of the world that is made publicly, is not even half of what governments and institutions from different countries have in hidden storage.
