I am thinking of buying an ASIC and start mining BTC. I just have 1 question to miners. Is it difficult to mine? I mean should I be a PC professional or have a computer science background to mine? Few people told me that I shouldn't mine because it is not something easy, and if i don't know what I'm doing, it might cause me trouble in terms of ROI.

I work at a bank from 8 to 6 everyday, so I won't have time to sit on the PC, but in order to make money, I should keep my PC running at least 20 hours a day. Is mining just plugging the hardware and letting the PC run alone to mine BTC?

I appreciate your help with this matter.

Thank you

I want to sell my lot for a fair price, but what might that be nowadays? Obviously I won't get my investment back, but I see them for sale ranging anywhere from .06 to .15.
