Even the simplest understanding of crypto currency shows why it is a fraud and why you should never use it.

1. You need to have a computer connected to the internet to perform any transactions.
2. Every transaction is tracked in a giant log of all transactions that is shared publicly with everyone. WHEN they figure out your account #, they have complete access to all of your transactions. Hiding accounts behind accounts will not save you, for the same reason shell corporations don't save fraudsters today.
3. Crypto is not and never will be secure. It is a matter of time and compute power to break any encryption. And guess who has access to virtually unlimited amounts of both? The VERY PEOPLE you are trying to fight.

These facts eliminate ALL possible valid reasons for using crypto currency. It is not private. It is not fungible. It is not secure.

What should you do instead?

Do what every sane person has ever done. ACCUMULATE REAL WEALTH. Own property. Make that property produce income for you. Get valuable skills that are ALWAYS useful. Raise a family. Make friends. These things will survive ANY economic disaster, including hyperinflation or whatever. Bonus points if you focus on food production, as you can't eat gold, ammo, or paper currency.
