After reading your response, I looked at the "hardware" forum section for mining, on this site, in order to find out what hardware people are using if they're not using GPUs. It all seemed a bit depressing, if I am to be honest. It seems as if the whole concept of mining is doomed to become obsolete because in order to be profitable, one must keep buying new hardware. I figured that finding lower electricity costs would be the main thing to worry about. However, it almost seems that even if a person were able to have free electricity, not a lot of money could be made because it will just get harder and harder to mine enough profit to cover the initial cost of the hardware. Am I right? This gives me a lot to think about.
Thanks for your advice and honesty. The funny thing about finding "current" articles is that if you do an internet search for bitcoin mining, good luck finding a "current" article because, as you have pointed out, fewer and fewer people are doing it. Therefore, any article that I find concerning ways to do it, are bound to be relatively old, and they talk about using GPUs. Not many people write about what people used to do, they focus on what people are doing now. And if you don't already know what people are doing now, and what the new thing is called, how do you know what to search for?
Thanks for pointing me in the right direction. A look at the "hardware" forum was a big help.
Lower electricity is always great. Sadly GPU mining there are some out there doing but for most including myself It's not worth it. Before buying any equipment decide of a ROI time-frame. If you have cheap electricity this will help. I personally don't suggest GPU's for most.
As far as mining there are two main choices Scrypt or straight bitcoin for most part. If you are looking into scrypt you might take a look at the new SF-28 https://bitcointalksearch.org/topic/guidelee-goup-silverfish-28mh-scrypt-miner-notlist3d-picture-heavy-650608 . If you compare the watts it uses compared to amount of GPU's to get the same it will show why I suggest asic. But GPU ofcourse will be mining a different kind of Scrypt.
As far as the day's of using computer with no investment it has passed. Just make sure to do some math and decide best option for you.
