I'm currently running 7 cards
the 7970's go for about $450 a pop
You join a pool to get a steady payout
so, like 5k on cards, say another 5k on setup 5 rigs (2 cards each) so 10k investment pays 1 bitcoin per week? and $120.00 per bitcoin(?) means $120. x 52 weeks=$6240 minus electricity? means like i make 5k from like 10k investment (+ electricity?) or im missing something?
thanks for the answers... much appreciated!
Which is why you would have to build an outrageous amount, the price of BTC will fluctuate, it was $266 last week before the crash, will it see it again? who knows, but as the difficulty goes up, your income will drop, so you ave to stay ahead of the curve. It's just like any investment, it takes money to make money. And if in the event that GPU mining becomes no longer viable, well I have PC's I can sell for $2000-2,500 a piece.
