You are building a straw man here. I’m not comparing bitcoin to the US dollar, I’m responding to your assertion bitcoin is a Ponzi scheme. Since there is demand for bitcoin in countries where people wish to move or store their money in a transportable, unanimous manner, there will be demand. A ponzi asserts the underlying value is zero. I assert the underlying value is not zero. It’s certainly not worth several thousand dollars but it is not zero. Whoever thinks that bitcoin will replace the dollar is clearly delusional, but that was not the original argument in the first place.
