Why you guys want to buy mining equipment unless power is dirt cheap and equipment too then buying is worth it besides the ASIC's manufacturers are your competition, they're making sure the difficulty rises to force you to buy more. If you bought coin two month ago at 4xx today you'll se profits. Mining is becoming less profitable every time difficulty rises and price stay the same. 1TH produces 0.035xxx a day less power consumption and cost of equipment plus difficulty rising almost every week do the math and stop supporting your competition.
