Any individual stock can tank to 0 as well. Enron would be a good example (fraud), though I see you at least had months to pull some of your funds out.

Hell, even an index fund won’t be safe if there’s another depression. COVID 2: this time even worse could happen at any point, for instance.

Gold might drop if we get asteroid mining going.

Bank runs can wipe out your money.

There’s no entirely safe way to store funds. Property, maybe, as long as the population keeps going up and the government is still functional.

It’s all risk/reward.
