Highly doubt gold will increase by much, it has been replaced in the majority of all industrial applications and the only real use of it is for Jewelry. People used to buy gold as an inflation hedge, but otherwise it is like crypto - it only holds value if people believe in its value.
You do not even understand how gold works, fiat is the one that depends entirely on the faith of the people to get its value, gold derives its value from many different angles, its use as jewelry and as a useful element makes it valuable, but its characteristics made it the best form of money in the entire world before bitcoin was created and its price tends to grow significantly when the economy is not doing that well.
