Give Bitmain another 2 weeks or so,the price should drop another $500...........I am hoping it will,otherwise I'm out of BTC mining............all BTC ASICS as of now are overpriced & the diff is going to explode within the next 2 months,75PH isn't too far out,by summer from the looks of it  

It won't be long before us "mine at home" guys are done,by years end if things keep going the way they are,diff rising & BTC price dropping.........................

The Gridseeds I think will be my saving grace,with soooo many altcoins to mine & turn into BTC & at 7 watts per 360 mh/s,they just can't be beat
