What should I own if the dollar collapses?

If the dollar were to collapse, what assets should I consider owning to preserve my wealth and financial stability? Should I focus on precious metals like gold and silver, or perhaps invest in cryptocurrencies as a hedge against inflation and currency devaluation? Are there other assets or investments that would be prudent to consider in such a scenario? How can I best diversify my portfolio to mitigate the risks associated with a potential dollar collapse?
