Price doesn't matter, profit does. And mining difficulty automatically adjusts to price so that the profit (also from transaction fees) tends to zero (whether from the top or from the bottom). I've seen the average Opex estimated at 60%, but that was some years ago...

(Also, an expectation of prices being higher than they "should" would mean that one has to consider an incoming crash and the whole operation should probably start getting wound down, so as not to be left holding the bag with now (almost) worthless cryptocurrencies and mining rigs. In that sense, yeah, you're probably better off staying closer to home, which I'll assume to be one of those "high consumer power price" countries.)
