what is tough is the power costs to btc price. lets say you have good gear for power antminer s-3's 6 of them and you get the full 500gh.
which is about 3th at about 2200 watts. that is 2.2 k watts an hour x 24 = 54 kwatts a day about 1620 in a month .
at 10 cents it is 162 usd
at 15 cents it is 283 usd
at 20 cents it is 324 usd
3th earns about 630 usd before power cost and all other monies.
margins are very tight waiting on coin say 1 block a week is hard if the money goes towards power and purchases.
the low btc price along with high diff made me leave here. I was here for close to 2 years
We haven't hit the point of 1 block per week; a few 3 and 4 day blocks usually followed by a couple of multi-block days.
What I don't understand is the need to instantly convert BTC to dollars. Power bills come once a month, at least where I'm located. Over 30 days, whether you mine at a large pool or a small pool, the average works out to be the same. Last month we had 28 good blocks and this month we've had 18 so far.
Unless we start getting to a point of regularly taking 1 week to hit a block, most people are going to be fine letting the averages do what they do.
