Mining profits are plunging and gpus have risen in price. That has led us to surplus of overpriced gpus. Nobody is willing to buy them with mining profits low. Another thing is quick coverage of algorithms with asics, we have an asic for everything now, and with second gen it will destroy gpu profits. We need more new asic resistant algorithms,
Yeah we cannot deny that profit in mining is lower now somehow it affects the droppings down of mining equipment price but in the other hand it is maybe the cause of low demand due to high supply because there are of computer companies who ares willing to manufacture GPUs.
