All mining operations that pay market price for their hardware, yes. Mining operations that pay marginal production cost, or very close to it, thats quite a different story. Their overall costs per TH are at least 5x lower. Most of those would be quite profitable. But they are not sharing their profits, they are only sharing their costs by selling (overpriced) hardware.
This is so true. Costs can be much lower on just a small batch order. Can't imaging what price are paid by projects that buy dozen miners - peanuts in regard to market price
