so miners are optimists about the future prices and they save BTC (and create more BTC, pump the offers again)or they are willing to tolerate to have lower margins because something is something, and sell at lower prices
so will the price rally up again on september ?
Miners don't have to be that optimistic to keep running. They just had to be overly optimistic when they got their rigs up.
Tolerate low margins? What choice do they have? Stop mining and have no margins? Whine about it?
Exact same choice as those who buy BTC speculatively. They can sell their investment and move on. In fact, since even 6990s don't drop 50% in 3 days their out is nowhere near as painful.
