I would say gold, but there is a "little problem" with gold. It is very hard to store it and keep it secure. Unless you are building a bunker ,your only option will be Gold ETFs, I could say that those things work and can bring you profit, but the situation with them is very similar to what is happening on crypto market now - too many project, and only a few have future.
But by using an ETF you are defeating the only strong point that you could make of it against Bitcoin: that it is a physical thing that you can own... some people need that peace of mind, for the thing to be tangible. However it's very clear that the fact that Bitcoin is intangible is a strong positive against gold, but goldbugs have a hard time understanding this fact, specially old people, there's no way to convince them otherwise.
The only one point I could make about gold is that it's more stable against Bitcoin, but this also has another side to it: The fact that it's more stable, means that it's harder for it to go up, whereas with Bitcoin since it's still tiny, the second big money comes in we are going to $250,000+
So all things considered, I wouldn't bother with gold, track record doesn't look good, and future wise it's not at all attractive compared to Bitcoin.
