Mining and block difficulty growth

I never really bothered to take much notice at that chart before. But now that I have, i'm a little concerned about my ROI... perhaps I should stop buying new mining hardware. What do you all think?

    Yes. You're unlikely to get your money back for new hardware, at this point, unless something changes. The difficulty is very likely to continue to increase substantially.

    Yes; I'd stop buying hardware if you were planning on a quick cost recovery, unless you plan on mining for at least the next 3-4 months with no expectations of profit until after that time.

    When I started only two months ago, diff was about 10.5T and 40MH was getting ~1.4ETH/day. Now, diff is twice that and 75MH barely gets the same amount. ETH is also 5x what it was, so there's that...

    Even at $11/ETH, a 25MH $300 card would take almost 2 months to recover if difficulty stays the same (which it won't):

    $300 / (.5eth/day * $11) = 54 days

    Bottom line: IF difficulty doubles again in another two months, price will have to double to maintain that 2-month target; otherwise you're looking at 3-4 months if price flatlines.

    Currently hashing away at 600MH, but a good half of that power was purchased in new mining hardware over the past 2 weeks. I'm tempted to double my hash rate with more hardware purchases, but am a little afraid of ROI. I got burned very badly in the LTC mining days, so i'm a little more cautious this time around.

    @hasher Ah, LTC... the burns are still fresh, as are the lessons learned. At least with ETH there's no ASICgeddon looming on the horizon; gpu's all the way. 'Till next year....
