Like Satoshi said, "The price of any commodity tends to gravitate toward the production cost." Bitcoin and every other mined crypto has tended to prove this out over and over again over the long term.
I guess it works better in reverse
So I could say that "the cost of mining a coin tends to gravitate toward its market price" (you can quote me on this too, ©). Really, the cost of mining is ultimately determined by the price of the coin. For example, if the price rises, we should soon expect the cost of mining to rise as well since more miners will enter the competition being attracted by increased profits. And this competition will eventually reduce profit margins to a minimum, which necessarily means costs coming close to market price. As to me, this inference is more correct
