Other than buying precious metals, what else can we do right now to benefit or at least tread water when hyperinflation hits?
No, and it seems too vulnerable to buy into. PM seems like a much safer bet.
1. Real estate, 2. cash-flowing businesses, and 3. Bitcoin.
Rental properties produce stable, predictable cash-flow. As inflation goes up, debt becomes worthless. Works until true hyperinflation and then you don't even want a home in the Weimar Republic, you want to leave. I don't think it'll get that bad.
Any business that people need will probably continue to be needed. Whether we end up using Chinese Yuan or whatever, it'll still be valuable.
Gold/precious metals are inflation-resistant for sure. I was skeptical of bitcoin, but eventually a friend who had conviction began talking to me about it consistently, and his ideas made sense. I owned precious metals index funds at the time, and our discourse caused me to shift to bitcoin, and no other crypto. Bitcoin has an asymmetric upside potential, gold has none.
The bitcoin/crypto thread on this forum has become more of a discussion of how to acquire more and etc, and less of a discussion about its merits, but happy to make my arguments.
If we come back to your question:
Other than buying precious metals, what else can we do right now to benefit or at least tread water when hyperinflation hits?
You owe it to yourself to honestly spend some time and an open mind learning about bitcoin. Its whole purpose is to provide an exit from money printing, and it has gained the critical mass it needs to explode. Money will shift to younger generations and the old people who hate it will die.
