Nothing wrong with Mini Fiat... At least you can hold their feet to the fire when they fuck up their policy or move to a better one. Fiat gets into trouble when it falls into the hands of the few. BTC is actual Fiat created out of nothing.

The only value it truly has is what you assign to it. What value you exchange for it. Unlike gold which physically represents the labor that was expended to acquire it.

Abraham Lincoln created a fiat called Green Backs. With it he purchased guns, uniforms, and munitions. Instead of borrowing interest bearing fiat from bankers across the ocean and he ended colonial slavery.

Again it's the principles that make money good or bad. Even gold backed can be bad as the bankers took all their fiat and bought all the gold!
