What should you own if the dollar collapses?

As the questioner, I'd like to inquire: In the hypothetical scenario where the US dollar were to experience a significant collapse, what assets or investments should individuals consider owning to safeguard their financial well-being? Are cryptocurrencies a viable option? If so, which ones would be most suitable? Additionally, should investors diversify their portfolios with other assets such as gold, commodities, or real estate? What factors should be taken into account when making such decisions? And lastly, are there any risks associated with investing in alternative assets during a dollar collapse?
