Octominer here. The big boys are still playing the big game. We supply big mining farms in USA and Canada with fully built GPU miners and ASICs. We are currently working on multiple 5MW+ projects, selling the new MicroBT M10(contact us for a great deal 
) SHA-256 Bitcoin miners and AMD RX580 8GB based GPU miners. The really crucial part here is the cost of electricity, most of our bigger clients have 4-5 cent USD electricity. This is really important for large scale mining to make sure you will remain profitable when BTC price is down.
