Once you start mining then you quickly come to realize that it's never enough.....
No...
I did with black erupter 30 that run 33-36 depend on temperature (its mean 10-20% higher) and never below 29 (-3%). Antminer 180 GH is randomly change speed from 160-180 (in specification) and yes it can do 180+ (some times 190), so it means it can run only 5% from its name but sometimes do 160 (-10%).
What I mean is when you pay it for the first time, you will imagine how much you will get. But in reality, when the product comes everything will be different. Like my experience up there. Diff will be harder and with many new competitor (miner) you got less BTC. So when the product arrive at my house, almost 3 weeks, the diff has changes 2 times.
1. Im hoping Antminer 180 would be 6 times from BE 30, and its wrong since Antminer 180 have about 175 in avg while the BE 30 have about 33 in avg. So it will mine only 5.3 times from BE 30 not six times as I imagine.
2. Diff change 2 times. I buy BE 30 first than Antminer 180. The first time I use BE 30 I gate 0.004-0.0045 per 24 hours. When Antminer arive I only get 0.018-0.02 per 24 hours. Yes it drops to 4-4.4 times.
Im not saying Antminer 180 is bad product. Antminer 180 is a great product, the less avg than it supposed been backed by its good software and automatic works. I loved to see more GH (or TH) product from Antminer...
Sorry Im bad in english >.<
Edit :
1TH antminer is coming @_@
