I don't really care about prices atm , but i think gold is gonna lose popularity with the years. Maybe to bitcoin or an other new asset.
Gold and silver have the unique attribute that their scarcity is secured by physics rather than code and data, so I think there will always be a special role for them.And it also helps that you can't create alt-precious-metals everyday!
This is not entirely true, yes gold and silver are uncommon due to being heavy elements created only when a star goes supernova but the universe is huge, once humans are able to get out of earth and begin to populate other planets natural resources will stop being a limitation, this is why we will need something like bitcoin because no matter what you do there is a limit in the amount of coins.
