Three days out, and network hashrate unaffected?

[Luno]

The price on used GPU's in this forum should be a good measure of the perception of future difficulty / price levels,

The market for used GPU's are existing miners and new entry miners.

So either people are believing that price is going to the 20-25$ range soon, or they are expecting a crash that will make difficuty go down to a level that compensate for the block reward halving.

If I was serious about mining now I would buy all FPGA's I could get my hands on, as they are priced favourable now MH/$ vise. That would still be a gamble that asic's will not take over (either because of delays or a smaller market than people think).

So everybody are waiting a little longer and running their GPU's while the price is still rising. If we see a serious price drop, people will shut their rigs off and their will be a fire sale of GPU's

Sigh.

Variance.

Spend some time looking at a network hashrate chart on a log scale and you'll figure it out. Or just read the posts of mine above.

7xxx cards are still profitable as they use less wattage per hash, it's the 5xxx and 6xxx cards that have a razor thin profit margin, if any at all.
plenty of 7970's making money though.

I wish the difficulty would drop quicker, since that would squeeze more out of FPGAs before ASICs...

Looks like a temporary weekend upsurge in total network hashrate.  More likely, than not, it'll go back to upper teens by Monday.

I don't think the estimated network hashrate is what you think it is.

5xxx and 6xxx are not profitable at all
7970 is razor thin like $0.33c per day right now, that's a long time to get payback on a card.

Finally we see hashrate drop! Now if it could just go down enough for ROI on my FPGAs before ASICs hit that would be very welcome!

Please turn your "environmentally unfriendly" heater GPUs off!

You probably aren't following this thread then:

If the foundry keeps up 4 layers a week from now on, it means ASICMINEr should receive the chips just before Christmas, so we could theoretically (hopefully) have something online before the end of the year....hashing the first ASIC mined block ever

then following that:

(~2-3 weeks)
First 6TH/s online
(~2-3 weeks)
Second 6TH/s online
(~0-4 weeks)
50TH/s of chips out
(~2-3 weeks, ~2-5 weeks if location changes)
Part or all of the 50TH/s online

wtf, now it's going back up again?!

EDIT: Ah of course, price went up 1 $... GPUs are back online...

And because of those coming back to BTC mining after giving LTC mining a try.

But yes, with the exchange rate up 10% and difficulty dropped by a small amount ... today it is marginally better than it was two weeks ago.

Though the ASIC onslaught continues unabated.   Not every promised ASIC design needs to ship to finish off GPUs, ... just one actually shipping will do that.

Or even some souped up FPGA monster.  Such as what yohan says they've got.  From another thread:

Before we ask for money you will be able to see the inital small system results in the network hash rate. It will be big enough to be noticed.

There seems to be a decent drop in difficulty, I hope it keeps going down to get more GPU profits before the Asics come in!

What makes people think that GPU miners will quit all at once, and no one will replace them? This isn't an orchestrated event. It's thousands of individuals discovering slowly that they might be unprofitable, and others acquiring FPGAs and replacing the computing power. There are also miners who have paid-for electricity. They have no incentive to stop mining now - especially not with all the GPUs from the miners who quit because they do have to pay their electricity bill hitting the markets and decreasing the price of used GPUs.
