Hmmm ok thanks for all the replies, I'm giving up on trying to mine with this laptop for now I'll have to see what I do next

Wow ok so I'd really have to buy a proper mining rig for this to work out? I was kinda worried about overheating as well...

Hmm may have to rethink this then, thanks for your help!

Hey guys so I just started this morning, I'm currently mining using GUIminer in the BTC shared pool. I've tried to read up as much as I can on bitcoins but there are a couple of things I'm still unsure about -


1. So I'm using a shared pool. How will my money earned vs electricity costs look? I have no idea how to monitor my electricity usage (I'm using a laptop) so is this actually profitable for me to run in a shared pool? I don't know how much electricity I'm using so if anyone could give me general advice that would be great. My graphics card is a GT 540M.
2. According to GUIminer my Mhash/s is about 8.7-9.1. Is this good or bad or what? I have no idea what a good or average value would be.
3. I know that mining uses GPU's to perform calculations or something, as I'm using a laptop is there any chance that mining will overheat my graphics card or ruin it?

Thanks a lot for any replies, sorry for any stupid questions

Hey I just signed up and I'm finding it kind of hard to get the hang of everything! I have about 50 tabs open that I need to read through now so gonna start working my way through them
