Bitcoin and gold have their own advantages, but are very different from each other mainly for one reason: volatility.
When you buy gold, you must keep in mind your investment isn't going to return much profit, as it's just going to keep its value through the stability of gold.
Meanwhile, Bitcoin investors are facing major and unusual profits by investing on this cryptocurrency, much superior to what they could make through traditional investments.
Both are considered strong store of value, but the risks involved and results achieved are too different. With that in mind, we can decide more accurately which one we should go for.
Gold is also volatile, although at a lesser rate than Bitcoin. Market prices can decline if central banks start raising rates, or if geopolitical tensions are eased. With Bitcoin, it's different. It can continue to go up, even when things are settled. For complete peace of mind, you should hold both BTC and Gold. At least for now.
Long-term speaking, Gold will lose its "luster" as a store of value. Especially if Bitcoin becomes the next "Digital Gold". But it's a wild guess, since the future is unpredictable. What's important is freedom and censorship-resistance. Bitcoin is certainly better than Gold in this regard. As long as it stays that way, nothing else matters.
