Well my main piece of advice that I am looking for is if I put down 2,500 for a bit coin miner at 50 GH/S will it be profitable at all in the next 3 or 4 months? Then I could just buy a bigger miner.
If you're going to pay 50usd/GH , I suggest you think twice about it.
After seeing the one malumeze86 referred. 1TH/s for $3527 I am definitely interested in buying that but I want to be sure it will make profit because the bit coin value does look like it is declining.
