(Originally posted in the "How many cards do you have mining thread", and moved to a separate post here.)
I'm (relatively?) "poor", being on a fixed income (disability), and all-to-often spending my monthly check on "expensive toys", and not having "food and gas money" for the month. That's where the mining comes in. It's kind of like an "adult allowance", every few days, I get $20-35 deposited in my bank account, and I have to manage it, and live off of it, right now. (Yes, I need to manage my finances better, I know that.)
So for me, mining is a lifesaver, relatively-speaking. It gives me a (small) extra monthly income, that becomes my daily or discretionary spending account. Now if only I could control my "ebay urges" better. Tech Addiction, indeed.
Don't hate miners. It could be YOU some day that's stuck in poor-ville, mining to make ends meet.
