The difficulty increase 3,182,542,067 equates to roughly the OVERALL network difficulty only 12 months ago

Nobody wins unfortunately due to this:
The good news is that the next cycle will have a 0.2 BTC bounty. I'll post the slightly revised rules when the new thread opens.

To win you must guess within 1 percentage point of the actual change.

and it was (+7.71%) not sure if we have a winner. I think buyandhold was closest at + 5.99% and that was more then 1% off.
As I understand suchmoon's promo the new guess will be .1+.1
I will leave this open a bit for suchmoon to check in..
I know those two last attempts were a little bit past the deadline but I'm going to count them in because the site was down for quite a while. Next time I'm going to include some verbiage in the rules to make it fair for everyone. So here is the final list:
railzand -3.00%
BTCish -2.00%
mavericklm -0.01%
notlist3d -2.50%
tarmi -1.24%
Kexkey -0.27%
SunnyIgor -3.20%
wpt1wpt1 +3.20%
stonerider +0.10%
davejh +5.50%
tsm13 -2.24%
alh +1.95%
skuser +2.00%
SimplisticStu +0.75%
buyandhold +5.99%
armedmilitia +3.00%
klondike_bar +1.55%
tss +4.80%
philipma1957 +4.09%
Let me know if I missed anything. No more entries will be eligible for the bounty, but please don't stop estimating/speculating/guessing.
I'd say +5% this time around. but a decrease next time if BTC stays below $250.

As I understand suchmoon's promo the new guess will be .1+.1
I will leave this open a bit for suchmoon to check in..
Thank you. 0.1 BTC for the most accurate difficulty guess, no strings attached, just some basic rules:
Deadline is 16:00 (4 PM) UTC February 1st, 2015, about 5 days from now and roughly 1/3 into the cycle.
A guess is a percentage with up to two decimal places (I'll round it if you put more than two) posted here in this thread. No PMs or posts elsewhere or anything else. Must include a "+" or "-" sign. No special "enrollment" wording or format is needed for the bounty - just post like you would normally do, as long as it's clear that you're predicting the next diff change percentage.
If you guess multiple times only the last one (not the best one) submitted before the deadline will be counted.
To win you must guess within 1 percentage point of the actual change. The guess that is nearest to the actual change wins. If nobody is within 1 percentage point the bounty will roll over to the next cycle.
Your number must be unique. If you would like your guess to be considered for the bounty please review previous guesses and make sure your number is different from all others. I will try to warn if I see duplicates but if a duplicate slips through only the first member who posted that number will be eligible for the bounty.
To determine the winner I will use the percentage shown by bitcoinwisdom (table at the bottom of the page) after the next adjustment.
To collect the bounty the winner will need to PM me their BTC address and the TX ID will be posted publicly.
Allow up to 2-3 days after the next adjustment for me to pay out, although I should be able to do it much sooner than that - just covering my ass I get sick/drunk etc.
I think that's it, if I missed something obvious let me know.
Edit: clarified that it's "within 1 percentage point" (not 1 percent, which might be confusing). So if diff change is -2.45% for example, you must have guessed between -3.45 and -1.45 to be eligible for a win.
Edit2: added a link to bitcoinwisdom.com difficulty page. Slightly clarified eligibility.
Edit3: as suggested by philipma1957 I'm reviewing the situation with multiple winners. I have added a condition that in case of duplicates only the first occurrence will be considered.

We had a decreasing difficulty last time and now we will just return to the last difficulty.
close enough to true. btw if we see-saw for a few months time up and down 5% with stable btc at 225 or so it does not kill my setup price wise.
What price do you need to break even not considering the cost of the equipement but just maintenance costs?
diff of 45.0 and btc at 160 I am good $ 5.50 a day
diff of 45.0 and btc at 140 I am good $3.00 a day
diff of 50 and btc at 160 I am good $3.50 a day
diff of 50 and btc at 140 I am good $ 1.00 a day
diff of 60 and btc at 160 I am good $0.34 a day
diff of 60 and btc at 140 I am down $1.65 a day
so I could stand diff of 45-50 and btc at 180 usd before I start to sweat.
So you still have some margin. If you mine at a loss, you are still acquiring bitcoins with a premium, up to 3% premium is fine.
yeah I should be able to hang in until June when my summer power rates hit.
What I usually do it sell 60 days early so Summer rates are June 15th I need to sell my in house around april 1st.

As you can see every day has been over 144 but Jan31st
Last adjustment 4 days over 144 10 under
note blocks made on feb 3 nice drop.
http://btc.blockr.io/charts
back up on the 4th
You can't quite chart perfectly with the above since the 27th is straddling both diff numbers
but 1233 blocks were done in 8 days 'normal' is 8 x 144 = 1152 so we are up 7.03% like I said we are missing part of Jan 27th and
today feb 5
on Jan 27th we made 145 blocks I do not remember the exact time we switched difficulty but if you include all of Jan 27
we go to 1378 blocks in 9 days normal is 9 x 144 = 1296 so we are up 6.32%
And 1 more big one 159
means 1537 in 10 days this is around 6.73% if you count Jan 27th
and the biggest number in a few weeks 171
this is 1708 block in 11 days = 155.27 blocks a day or (+7.82%).
What does it mean?
I would think a big boy like KNC or Bitfury is bringing a plant on line. Others may want to say variance but not this time.
[/quote] feb 7th was 162
that is 1870 in 12 days = 155.833 or (+ 8.21%)

+ 7 or +8 are both high we look to be very close to 44.7 - 44.9
either one will be an all time high
Looks to me like suchmoon won't be paying out anything at this time. I think there's only one member that has a chance at this, and that's if things slow down some in the next 36 hours. If this is actually variance, then we shouldn't see another big increase after this upcoming one in a day or so. While I am no math wizard this seems like a real increase, not just statistical jitter.
The hashrate for the last 502 blocks has a high variance but the difficulty will increase in 1.5 days, it will be about what it was before the last change.

It's gonna be tough all round with BTC holding in the low $200's and diff looking like it's going up again
Its even tougher for ppl holding their miners hoping to get ROI.
Phillipma's opinion does not count because he got "free" electricity with his rent. I feel bad for ppl who just bought some miners tho....
however, it is a good time to get *some* used gear at good prices. I pay $0.09 USD for nighttime and $0.13 in the daytime/peak, so am still somewhat competitive.
and im hoping to move into ~$70/kw/month colocation very soon
I am not aware of $70 colocation. Some come close, but most with long contracts.
You probably would be better off by selling 0.5-0.65GH/w gear anyway and go for 0.2-0.3GH/w gear if and when it shows up
so they can survive at ~220$ a btc for 3 weeks....
Difficulty is a joke right now with the recent price slump, where's all the hash power coming from and how are they affording to operate?
well if it is not variance and it is hash, then it is a major company using 'special' gear
Say bitfury adding 30-50 ph.
In theory they should be building a major plant in the north of Finland or maybe Iceland.
