So if the difficulty goes to +8.01 or higher to infinity does CrazyGuy won automatically?

Or is it considered void?

To win the difficulty has to be within the range you guessed, no exceptions. If no one wins the reward gets added to the next period's reward. Current reward is 0.2 BTC because no one won last time.

[VirosaGITS]

0.2 Is going to be a nice Juicy bits. It look like the winner will be very close to the 5% range. It kinda feel like 5% is the new Norm for the rest of 2015. Meanwhile the BTC price seem to be holding at 230~. For now.

we are under 5%

If we get it under 5 I will consider it a little win since not rediclous amount.   But I am still worried of weeks to come.   

I just wonder how many S7's have been pumped out.  Also with it going to be on hashnest in October if those machines have been made already and plugged in mining for Bitmain, of if we can expect a big batch just for hashnest to come.

Well the only good thing is we know the S2's are offline, and I expect a good bit of those to stay turned off.  No doubt the S7's that are pumped out will keep increasing the hashrate, but we are def getting to the point of no return for the older generation machines that are stretching their last bit of life.

I would not say we know that.  With cheap electricity in some places I don't see them just piling up S2's and letting them die.  Likely they would try to find a buyer and sell as used.

A1/S2 stuff I think a lot remains online.   It's hard to say when we will lose all of this gear.

[VirosaGITS]

Indeed, i am still running S1's (undervolted) so i would definitively want to run S2',s if they were quiet right this moment. I'm assuming they have a plan for all that hardware. At any rate, they would make good heating units for electric central heating in houses.

So Other than personal miners that decide "they are obsolete so i am going to put them in the trashcan" i don't think S2's are going to go offline yet.

[wlefever]

They are offline from Hashnest and I don't think anyone is rushing to get them all back online. Sure they will sell them as used to someone interested with cheap power (aka someone in China), but how much life are left on them by the time you purchase and get it set up assuming were talking a large farm?

Also note I never said they were obsolete but they are def on their last leg per say.

I'm pretty sure S2,s are still profitable in China, and for Bitmain. So i'm not particularly sure Bitmain offlined them. I mean its possible but its not because they stopped payouts at hashnest based on return/cost rules (based on the amount they charge customers, not their real cost)

Because i'm pretty sure they pay much less than than 8 cents per kWh. Or maybe they were offlined because they needed space or for some other reason but regardless, S2's are still profitable here with Hydro so i would assume China have even better rates.

This sadly i'm not sure this will contribute to a difficulty drop just yet. Would be nice though, since the BTC price isint keeping up.

They have no doubt found the cheapest electricity.   Pulling them from hashnest is not the same as them stopping mining internally with them.  It would not surprise me if they pay 1/2 or less then that 8 cents.   

But yea don't count on them going offline.  Just like A1's they are running somewhere I believe on most.

I am running 4 s-3's at 2.4 cents they earn around .014btc a day  the power costs me about 15 usd a month.

you can put an s7 in the place of the 4 * s3!  


Bitcoin Difficulty:    56,957,648,455
Estimated Next Difficulty:    59,938,071,210 (+5.23%)
Adjust time:    After 389 Blocks, About 2.5 days
Hashrate(?):    417,794,711 GH/s

the higher we go in hashrate, the higher the variance the swings will be
maybe in the future we will have even 5% swing from one day to another

yeah if i could make it quiet.

And also come up with $2000 roughly to earn a bit more. The S3's are a sunk cost more or less. Phillip's specific situation is unusual, and putting in a "big money" machine will do nothing but blow whatever profit he already has.

As I understand it, the S3's may not all be in one location, though my memory may be faulty here.

So if the difficulty goes to +8.01 or higher to infinity does CrazyGuy won automatically?

Or is it considered void?

To win the difficulty has to be within the range you guessed, no exceptions. If no one wins the reward gets added to the next period's reward. Current reward is 0.2 BTC because no one won last time.

I didn't know the reward was accumulative that said it will be interesting to see who wins seeing as there are only a few hundred blocks left and it will only carry forward if it passes 8.26% this round which may be a good pick next difficulty seeing as units may start to come online as philip mentioned with the S-7s.

Bitcoin Difficulty: 56,957,648,455
Estimated Next Difficulty: 60,181,868,441 (+5.66%)  
Adjust time: After 358 Blocks, About 2.3 days

I really want to stay under 5 that would be nice but I don't think it's going to happen.   I really want to know if bitmain has already gotten their own internal miners up and running (specifically hashnet ones), or if that is coming in future.

 They are in my friend's office.    And they use up about 1450 watts which is all I can do in his place.

yeah the s-7 would be nice but as you say 1900 plus to use the 2.4 cent power.

A second issue is his lease is up on Jan 1  and we do not know if he will continue in his place.

But I did mine from May 2014 to Sept 2015 so far.  First with s-1's then with s-'3's.

This gear has roi'd in btc and usd including the psu's in use.

I have a second spot in the brooklyn navy yard  I have a 240 volt 30 amp circuit I think the s-7's on order will end up in this spot.

The issue here once again is noise.  I may run the s-7's as low as 3600gh with these mufflers

So how are you getting all these awesome friends for hosting? I have to admit I'm a little jealous of your ability to find cheap electricity.

I do look forward to you making it quiet.  I would love to see some S7 "silencers" for lack of better term.

[VirosaGITS]

Hmm, mufflers. That sound like a great idea, but pretty expensive.
I guess for a S7, its such a big unit that you can soak it, however.

But i'm wondering if i could not DIY one. I'm guessing its just the foam used in sound absorbent panels rolled in a tube of aluminium.

I would have to see how its made but i'm pretty sure with some cheap aluminium sheet that i already have at home, buying the sound absorbent material, i could handcraft one. (With a healthy dose of duct tape)
Edit: Looking at pictures of it from other angles this would be very easy to make. Its just rolled foam.

But i'm guessing you might want one at intake and exhaust?
