What's backing the dollar? Inflation? Spiral debt? Violence?

The fiat system is not backed by anything tangible, it's just based on faith and such faith is being eroded very fast.

Bitcoin and gold are bearer assets i.e. don't need backing because the assets backs itself.

Bitcoin is an immutable protocol and a global network that can resist any attack while producing value. Bitcoin is math and math doesn't need backing either.

Only fantasy assets like the dolar need faith and trust.

You will never understand this because you've been brainwashed beyond repair. I wish you luck with the incoming fiat collapse
