Gold has value because it’s rare and is falling short in supply each day.
Diamond has value since it’s also rare and precious stone.
Fiat is loosing value as it’s unlimited and can be manipulated by Governments.
DOGE is a meme coin. It’s unlimited in supply, it’s garbage with no utilities, just a random hype has been built over it and thanks to Elon Musk, it reaching ATH’s one after the other. It’s a bubble and will burst hard probably the biggest rugpull you can even imagine.
