I've mined in the past, but I don't understand how it works.
I have £200 and want to know what the best BTC software I can get is.
Also, I'm in the UK, please consider electric bills. How much would I make per month?
I also have an i5 3 GhZ computer, quad core, 8 gb ram and a decent graphics chip.
The best thing you can mine with your i5 is CPU coin. But none is profitable right now so you should just forget about mining (you will be paying more electricity).
