Hi all,

I've been reading forums and hearing mixed comments so I wonder if a few of you could help answer the question. I have a 15Ghs rig going at the moment and its generating around 0.02 BTC a week, at this rate I would have made my money back in around 3/4 Months (at the current exchange rate)

so this is making me think, if I spend more money would I be able to cover cost and even make on top?? I understand the risks due to exchange rate etc but ill still have the bit coins.

I have £2500 to spend on kit. the question is should I? and what should I buy in terms of mining equipment?

Thanks in advance

Can anyone shed some light on what the worker difficulty thing is all about on BTCGuild?? im running 15Ghs and im womdering if i should up the difficulty on the worker??
