My wife though is still into gold.
I'm bullish on Bitcoin all the way through, but have to admit that Bitcoin in general terms is still a high risk asset, especially amongst traditional investors and average joes. In other words, your wife is likely to do better going for Gold in the short term. Gold has had thousands of years to gain trust, while Bitcoin is the new kid on the block. It will take time for Bitcoin to become a safe haven asset, but I'm confident that it will happen.
Storing physical Gold is doable in smaller amounts, but a total disaster when it concerns so much Gold, that you have to buy a massive vault or have your bank store it for you. Storing large amounts of Gold in a vault yourself comes with the obvious risks of thefts and whatnot, and letting your bank store your Gold for you means you don't actually own it anymore.
Bitcoin for average joes can be stored conveniently in a hardware wallet. Even if someone takes it from you, they still can't do anything with it as long as you have your recovery seed hidden in a place only you can find.
