If one year an apple costs 2 gold coins, but next year, that same apple costs only 1 gold coin - this would be deflation. I'm still trading gold coin(s) for an apple (fungible), it's just that the currency itself got stronger against the asset I wanted to purchase.
The currency (or asset) will continue to outperform the dollar or any fiat currency because it is setup that way to scale inversely and inverted-like through the magic of fungibility.
No one no where ever created a means of trade accurate to the ten millionth. Go look it up I’ll wait.
Just because something scales inversely to your currency that doesn’t make it a ponzi, it makes it mathematically and theoretically possible; as the market itself has proven for nearly a decade.
