i mean if invest $30k in a bitcoin miner it better net me a guarantee of sorts.....what kinda income will this net you???
That rig will get you about 1,500 GH/s
At current difficulty, that would net you approximately 172.71 bitcoins per day, and at an exchange rate of $47, that would come out to $8117 per day.
That calculation does not take into consideration electricity costs.
It also does not take into consideration that mining difficulty will likely continue to rise, which means that you will mine less and less bitcoins as more and more people get ASIC's.
