If the US dollar were to collapse

In a possible collapse of the dollar, the whole world will be affected, and any asset you hold with third parties will be seized. If you have gold, silver, and many precious metals in custodian accounts like banks, it will be taken. If you have money in your bank account, it will be seized while you lose purchasing power.

On any collapse, the government first does get the exits closed; they don't let you take your money or assets out of your favorite custodian services by limiting the number of assets you can withdraw. The government does this to prevent capital from fleeing to other jurisdictions, not to mention that in collapses, basic essential services go offline, including banks and their ATMs.

And the same will happen to those intelligent enough to leave their crypto coins on exchanges, custodian services, or any other service on which you don't control your private keys. Stop being competent in the wrong direction and get your money out of third parties applications that yield interest because in the time of the collapse, the government will force those services to surrender your crypto, and you will get worthless paper; if you think crypto is the currency but you are leaving your assets on custodian services you will be taken to the cleaners like everyone else in the coming collapse.

By to way, governments will want to seize that which has value and give your worthless bills, just like when they did with gold before. Third parties will be the easiest for governments to take or seize, or they will put those CEO s in jail, so your custodian services will sell you out in a heartbeat.

In a collapse situation, electricity may fail, so it is always a good idea to have some physical assets like gold, silver, and some cash but never on amounts that will slow you down if you need to flee. Money works when the electricity goes out, or there is a disruption of service utilities.

Pretty much Bitcoin and other cryptocurrencies are good to start over somewhere else or to preserve wealth from third-party confiscation, and that includes first. Most governments like to take citizens' property to finance either their pet projects or to fund whatever else project they may have, but with your money and in exchange, they will give you worthless pieces of paper as they did to gold.

And in a situation like the one that Ukrainians are having, you may need a genuine peer-to-peer currency then a useless store of value that can't be used thanks to transaction fees being as high as the sky. You can bet that the transaction amount daily will increase in a crisis scenario. That means you need a cryptocurrency that can support that usage hike without notice and custodians; that currency is Bitcoin Cash BCH, in my opinion.

You have been warned.
