Both gold and Bitcoin are considered stores of value. However, gold has been around since ancient times, while Bitcoin has only been around for 15 years, having been established in 2009. Gold has been a valuable asset since ancient times and it is widely accepted around the world, while Bitcoin has not yet gained the same level of acceptance.
Governments are gradually moving away from opposing Bitcoin. They are becoming more aware of how they can accept Bitcoin. Where gold took thousands of years for people to build trust, I think Bitcoin has improved from that position in a very short period of time.
Both are needed as for now, imo.
For different situations that are engulfing the market, bigger entities see gold as a more stable option, and they are only adapting to use BTC in the cases reasonable for them, and I agree that opposition to BTC will end eventually.
