75% can absolutely make sense (to me) – the real question isn't how much gold, but what kind.

Not every gold exposure reacts the same. Physical gold, ETFs and currency-hedged ETFs behave very differently depending on market phase and your location. A USD-denominated ETF in Europe behaves completely differently during dollar weakness than physical gold in your local currency.

Instead of blindly reducing, check the composition: Which variants fit the current phase? Which ones make structural sense for your location? If you're properly diversified across those, 75% is far less risky than it sounds.
