Note to all I open and closed all 2014 diff threads they are now more lumped together and since locked should stay this way.

In a day they will drop down but since locked will stay together.  Kind of an interesting history.


Okay last diff has come and gone.  It was [-0.58%]

tlhIwI got it correct.  Congrats.

Picks will start at block 300 and end at block 1000




Look at this set of numbers below  pretty impressive:

We are  under an 0.6% average for 10 jumps.

Do not pick until block 300
Lastly we are at https://bitcoinwisdom.com/bitcoin/difficulty

(-0.19%)


with 1991 to go.

maybe we can go lower again :D

That would be nice for sure.  It's early so I expect it to jump around but bitwisdom now showing slight positive:

Bitcoin Difficulty:    49,402,014,931
Estimated Next Difficulty:    49,465,478,088 (+0.13%)
Adjust time:    After 1955 Blocks, About 13.3 days

Well with the pricing being mentioned by Sfards I think network will be flat. They will self mine 1 or 2 ph of their gear for this diff adjustment.

Which is not much compared to the network.  I also think the 'real' summer heat is not here yet and more of this heat will kill gear.

What will be interesting with them is what LTC market does.  A2 has been king of scrypt chips for way to long.  If people mine LTC with new chip and dump to get BTC could be interesting to watch.  

As far as BTC I'm very happy with the summer.  Were hitting 255 currently and difficulty is still low for this change.  Looks very nice.

6-28-2015  145 blocks 144 is normal   but we were partial for sunday.


https://blockchain.info/blocks/1435508323699



362977    23:54
362837    00:07

this is 141 blocks for 6-28-2015   norm is 144

the time is not synched so there is a difference between sites.

basically we are flat and close to 0%

with price over 253  things still looks okay.

first day we started at block 362870 ended at 362977  so we did 108 blocks.


362977 23:54

362870 05:44

108 blocks in 18 hours and 10 minutes  norm = 109

Late night bitwisdom looking good still:

Bitcoin Difficulty:    49,402,014,931
Estimated Next Difficulty:    49,237,574,589 (-0.33%)
Adjust time:    After 1747 Blocks, About 12.0 days
Hashrate(?):    341,713,015 GH/s

Price currently over 260 ... so very nice day for miners.

Morning Bitwisdom has slightly went positive:

Bitcoin Difficulty:    49,402,014,931
Estimated Next Difficulty:    49,845,509,110 (+0.90%)
Adjust time:    After 1705 Blocks, About 11.5 days
Hashrate(?):    341,060,269 GH/s

And price is still hanging above 260

with the price is rising so nicely, i doubt, this time will be positive, i think i'll pick the same but +1 increase(if it will be available), i'm still not sure

The basic flattening of the network difficulty has provided far more life from my S3s than I thought they would get.  I never once thought I'd see a year's worth of mining out of them when I purchased them... I figured they'd be replaced or sold by January of this year at the latest.

Of course, there are persistent rumors that BitFury is about to power up a ton of their next-generation gear.  I'm sure Bitmain is already working on the replacement to the BM1384.  Spondoolies, I'm sure, also has something up their sleeves.

Okay here we go pick time.


With coins at 268 usd
you know diff will rise a bit.

(+0.25%) current


and will we finally go up and over the 50 bill diff?

I think so as long as price shifts up.

I would like to take +0.51% - 0.75%

Thanks !

+0.51% to +0.75% -------------------- HerbPean

+1.76 - +2.00.  The upward price trend might entice some miners to turn hardware back on, but I'm not sure how much of an impact it's going to have overall for this difficulty adjustment.

I can never guess right when it zig zags like last time  :)

i want this range, this time

+5.25% + 5.5%

usually the diff reflect the price with a delay, and usually it will reflect the possible next increase

price is dropping.

 the Greece bailout may happen which will put downward pressure on BTC price  also put downward pressure on diff numbers.

A lot of high picks over  and only I am negative.

Would be funny if we go minus.  10 days left anything is possible.

I was going to pick negative, but I feel like with slightly higher prices no way we see negative adjustments back to back! Going to be interesting to see it play out.

+0.01% to +0.25% Please

a bit surprising to see not a single negative prediction and the + side filled up.

Well, the rate of ramp-up by Bitfury and possibly 21e seems to be constant, and the rate of hash-rate reduction due to temperature/electrical hindrances should slow down with the higher price of coin, not to mention the natural wave of hashrate should bring us up a bit after the last negative difficulty change.

So far so good, but summer is only 6 days old...

well yeah but so far so good.

I am doing a thread on gear right now it is an sp20 thread.  
I am trying to determine failure rates.

on the:

 sp20
 s-5
 s-4
 avalon4.1
 sp30
 sp31
 sp35
 sp4+

I think many miners say fuck this shit when a piece of gear dies.  and this contributes to downward diff pressure.
I bring it up here because the heat of the summer is going to be killing more gear.
I can see low diff for 2 months. with no real worries.
The underclockers of gear like myself may become big winners since they never kill gear. Well hardly ever.

-0.01% to -0.25%

I think it is going to jump hard next round. Hopefully not! Has to soon though.
Seems as though BITMAIN would be hitting the test benches with new product right about now.

-0.26% to -0.50% please.

I find this guess unlikely, but since I won the big one last week I decided to sit this one out until late in the guessing and choose whatever was available.  I actually expect a positive this time, but not a high one. 

With the price going up we will probably see difficulty going up (assuming the price sticks), but I would expect a little lag time before that kicks in.  I'm not sure exactly how large farms negotiate their power cost, but having consistent constant power demand (I can't remember what this is called off the top of my head) or at least a minimum usage might play a part.  If that is the case then an otherwise unprofitable farm would need to ensure at least a month of continuous operation before restarting.  Of course, I have no idea if this is actually the case or not.  I do know that around here there are discounted rates for exceeding some high amount of usage (though here isn't the cheap place to put a farm and options vary from place to place).  If that holds true elsewhere then there is more involved than the daily BTC price in deciding if it is profitable to restart a farm or not, thus why I expect some lag in the start/stop decisions. 

I'm quite enjoying the current diff situation.  When I bought my rig in January I expected to be reselling it in May.  It's now July on this rig and, unless diff really shoots up extra fast, I still have enough headroom for undervolting to make it through September and maybe even beyond.  If I can make it to winter then heating offset options are even available to squeeze out a few extra months.  I never thought that would ever be possible.  I may even ROI without selling the rig... imagine that!

59% no to 41% yes with 10% of the vote.

I have to think  the no vote will


A: Cause a big run to BTC for Greeks in the know.
B: 300 usd plus for BTC
C: A solid  diff increase if you get up and over 300usd and stay up and over.

I can see 5% for 2 diffs in a row if we stay in the 320 to 350 price range.

+ 2.31% is perfect  :P

Im wondering if Greeks cant withdraw all cash from atm how could they buy Bitcoin ?
Can they use the online system ? I guess the banks also take down the online stuff, no ??

Funny you should ask.  I used to live in New York City.  I was born in Queens and when my wife and I got married we lived in Astoria Queens for 6 years then moved to  New Jersey near the shore.

Astoria Queens has thousands of Greeks both resident Aliens and USA citizens.  I know a few people even though I have not lived there in 20+ years.  I am sure plenty of BTC is being purchased in Astoria and then sent to Greece as I type. At this point the vote is 60-40 no so you can be sure they will need some kind of money remember Greece has ties to Cypress so I am sure plenty of them remember BTC helping smart ones in Cypress.

This Greek crisis is an example of  the single biggest reason I like BTC.   It can help you if the place you live in fucks up with money.

we made 76 blocks in 8 hours and 40 minutes the norm is 52  this is a 210 block daily pace!
I don't think we are going to have a 210 block day

The Greek scare is definitely not over... Japanese and US markets opened way off.  DOW was down over 150.  BTC is around $275.  Bitmain just jacked UP the price of an S5 (totally irrelevant, but thought I'd throw that little tidbit in here :) ).

yep and the pace for today has dropped from 210 to 200 block day.

still huge.  200 blocks or 210 blocks  are both over  40%  jump.  I have been tracking daily for about a year IIRC 185 has been the biggest daily number.


 My opinion is older gear has been turned back on and a lot of farms are hoping the Greek collapse will be just what is needed  to drive coin price into the 325-350 range.

210 block is crazy!  :-\

I remember a month or 2 ago I read a article about gear that will turn in when price go up.
In the article they name this effect. Will try to find it back. It was really interesting and show that the actual hashrate will go up if the price go up.

Looks like the BTC price will push up the Diff now.

looks like 3-4%

My hope is a lot of expensive gear was turned back on  by people hoping price jumps a lot.

If this is a shit ton of new gear  it is really more then I thought possible.

Of course variance is possible the time period I used to calculate 210 blocks is small.  The next calculation dropped it to 200 blocks.

https://blockchain.info/blocks

So far we made 128 blocks today in  16 hours and 10 minutes

we should be at 97  so   128/97 =  1.31958    and 1.32 x 144 =  190 blocks


so part of that 210 then 200 then 190 projection for today is variance .     But for now it looks like we will move up this adjustment.

I'm certainly hoping it's not a bunch of miners firing back up old gear just to mine and dump.  I'm also hoping that it's not a new 20PH farm that's come online either... in any case, though, certainly looks like we're in for a positive adjustment.  Hopefully this is just some variance spiking and it'll come back down :)

I suspect some big farms  keep some marginal gear on hand just for an occasion like this.  Price spike of 10% flip a switch and turn on 1ph of s-3's

Looking at a longer time horizon, difficulty has increased by roughly 21% during the 1st half of 2015. In the last half of 2014, the difficulty increase was roughly 140%, with about 20% in the last 3 months of 2014. Clearly the rate of increase has been slowing since Mid 2014. So while difficulty has increased, and will likely continue to do so through 2015, it's decelerating.

A small bright spot.

Do you?  I was thinking something like that, but then I had to think of the space that would take up, the effort to maintain all the hardware that you rarely use, etc. etc. and I just don't see it as a very profitable or workable theory.  If a farm has the rack space then they're probably using it for gear that's running.  Marginal gear does not get left sitting around, hooked up and ready to go.  It gets removed from the farm to make room for more gear!

I think the profit margin dictates this behavior and the corners farms cut to maintain a profit lead me to think that the scenario of keeping marginal gear around and connected to network and power to only be used on rare occasions just doesn't make accounting sense.

it does  if your are selling off s-5's and replacing with s-7's.  Then have the s-5's  go back to mining while still having them listed for sale.

I should have been more clear.  oh 176 blocks made today with 40 minutes to go.

https://blockchain.info/blocks

Later today I will map out what I said a little more clearly

While your math makes sense, I can tell you that no one is doing this. No large farm has that kind of space available. All the majors are constantly looking to fill any spare space, and they'll pay more than your old gear will make you. Go ahead, get a MW set up and ready to fill and cool. And then wait for the price. You don't: you fill it with someone willing to pay. Simple business. No one is sitting on MWs of capacity. I would guess that "spare" capacity is less than 5 MW through the entire network of space that has low enough costs to be competitive.

disagree but my  example takes into account a lot more info then yours. It hinges on my belief that asics builders have tried to keep diff lower in order to avoid an arms race.

So in the fall I am Bitmaintech I swapped out my s-3's for s-5's



 Now in the spring summer I swapped out my s-5's for s-7's

I don't try to grow like mad I grow a little and I lowered power bills with better gear.

If I fully swapped out from s-3's to s-5'  to s-7's the network would have grown faster.
Same goes for the other companies.

If companies fully swapped and kept all places maxxed  the hash rate would be better. more like 400 or 425ph.

I appreciate that "you took into account a lot more info" then I but take my word that I'm well positioned in the industry and not a home or hobby miner as you are.

There is very little spare hosting capacity out there. No one (other than home miners who are less than 1% of the network) was sitting on machines through February and March. If you weren't profitable then, but are now, you're going to be under water again in 8, maybe 12, weeks, so that is dumb strategy. (ie. a 20% price rise makes you profitable again, so once difficulty catches up with price, very soon, you will be under again. Furthermore, your "carrying costs" of the data centre, like your mortgage/rent/insurance, will ensure this strategy yields less profit as you paid that money while waiting for the price to rise. Furthermore, these 8 to 12 weeks of "back in business" are going to be barely profitable, if at all.)

And from what we all know, chances of those machines being "back in profit" ever again, after surviving retirement once? Little to none.

If my mine was 20% away from being "underwater" I'd be sweating. Not going "Gee, I'm going to plug all this back in when the price goes up". Running a large operation is expensive. As I said, mortgage, rent, insurance, internet, security, employees (you can't just fire everyone and expect them to come back after 6 weeks of unemployment).

Rather than mothball your facility, if you were giving up you'd probably strip it of the electrical (resale on transformers, panels and HVAC is good) and sell the building and land.

Now - your argument is not without merit. If we saw, say, bitcoin return to $500 in the near future. Then yes, everyones going to be opening a mine everywhere, and you will see stored equipment come online. But not at $270. Not enough incentive.

Edit: Also, on your last point about majors maxing out their capacity. Believe me, they're trying. Between fires, equipment failures, bankruptcies, etc. this hasn't been an easy road for most of them. KNC's mine appears to be under water. Bitfury (who are doing fine now) had to shutter a mine in Finland over the winter. We see all of them needing equity investments. If you are making good money, you get debt, not equity. Equity is for companies that need to expand in order to survive.

 so if  home miners have  1% of the network , 3 to 4 ph out of the network?  and 4 ph earns about  41 btc a day. or 1.6 blocks a day.

below is f2pool's payout for july 6th 2015

https://blockchain.info/tx/6a8c32b23b795a8c700e5e46f62151686ac2156ce1c27b8833a7caf0f44df8f0

they paid 700btc to 697 accounts

11 th would have paid .1 btc

80% of the payouts where for miners under or close to .1 btc

they are 1/5 of the network . So you 1% of the hash is from home miners means you don't count guys with hash at f2pool.

I think if we merge my ideas with yours we get closer to the truth.

I also think based on my f2pool studies more then 10 % is in home mining  not 1% .

I would imagine builder/farms   are closer to capacity. then I am saying.  But I am sure home miners are at 10% of the network and I know a lot that have idle gear.

so it is a bigger factor then you think.  If home miners have 10% of the network and can boost there mining 25%  that means they could change 35ph to   45 ph

or a 10ph boost. that  is 3%.  I still think bitmaintech does not run at 100% capacity at certain times.  When they swap  s-7's for s-5's which would be now.  the hash stays flatter and the power drops.  I know you think it is a full power level and for all I know you supervise the swapping out of the gear.  so you are certain it is a full power level model for profit.
 If so too bad  as the gear race will never end if you are correct.

To add to Jamphone -though I am a nobody in the industry- manufacturers aren't worried in the least about the total difficulty/hashrate, they are concerned with their own market share of it, and specifically maintaining/increasing that.  Increase of difficulty is the natural by-product of competition and capitalism in the mining world, and if manufacturers took measures to try to keep the global difficulty down, it would mean they were sacrificing their own revenue in the process.  That just does not happen.

well I do see looking at it that way and it certainly may be true. time will  tell if you are correct that is the method they use.

or if they moderate my way and maintain hash rate share by cutting power  and less growth then possible.

I suspect they mix methods and constantly look at other big players.

many ways to get things to work well together.

No, I count them for what they are, hosted miners on separate accounts. F2Pool is roughly 65 PHash. That's at least 40MW of power. While undoubtedly some are home miners, most is large scale operations. Perhaps 1% is too low, I still doubt it's 5% of the network. And among those home miners, I'd surprised if they had even 10% idled power. Why would they? Older miners have lower hashrates which makes such a large amount of idled power even less likely.

Well its the summer.  A lot of home miners turn gear off in the summer due to higher power rates.

as for f2pool  I can fully break the coinage down. takes about 15 minutes.  they paid out 700 coins    I think at least 40 went to payments under .1 btc which is about 10th.

this is an address from f2pool payments

https://blockchain.info/address/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje

585 coins of 697 were paid  from 65 btc down to  .2 btc  which means 112 coins were paid to   miners under .2 btc
637 coins of 697 were paid from  65 btc down to  .1btc   which means   60 coins were paid to miners under .1 btc


112/697 = 16% of the miners on f2 pool are at 20th or less.
 60/697 =   8% of the miners on f2 pool are at 10th or less.

antpool  is close to the same.

as is the other big Chinese company

So  8 to 16% is home mining by the little guy.

 not 1 to  5%

Now I know Great Northern Data we have talked a bit.  About hosting ..


You host have many 10th and under do you have>   percent wise  10 percent or less?


 I suspect most that host  with do a lot more then 10th with your company..


But there are a lot of people that mine like I do.  More in the winter less in the summer.  Due to heat and due to power cost.

This year I said fuck it. and I don't have much gear in house.

 but if I had  5 avalon's  I can move them from 800gh each to 1000gh each or 4th to 5th if I spec that we see a bigtime coin move.

 alot of us have sp20's  clocked at 1100 to 1200 gh   but we can bump them from that to 1350gh easy.

you guys are underestimating  what home miners can do.  and I think part of the problem is  you are not the farm in my explanation your are a data center .  you need 90% + cap to survive.  asic builder-miners like bitmaintech have a set of 4 to 5   factors you don't have.

   But maybe I am mistaken.

I think it's impossible to separate a small increase in actual hashrate (i.e. new or secondary hardware that's now active), from just variance. It seems you can really only appreciate increases in hardware from a retrospective of difficulty increase, and one change doesn't say anything.

I think it's safe to say that there hasn't been any REAL increase in hashrate for the last two months. The difficulty is roughly what it was 2 months ago (See June 14th and April 5th).

This isn't going to last for the remainder of the year. SFARDS is selling (or self mining) with previously non-existsent hardware. There will be something from Bitmain that's faster and more efficient than the S5, regardless of it's exact designation (e.g. S6/S7).

My personal feeling is that this next difficulty change will put in a new "floor" for difficulty. It may not be be quite 50 billion, but it will be 49 billion at least.

I have absolutely no idea to reconcile the competing views about what a self-mining company does with more efficient gear. Do they replace "for hashrate" (and lower costs), or do they just match Watts and increase hashrate. The last few months suggest very little of the latter. I don't know what happened to the S3's that got displaced by S5's. Some got relocated to a Hydro rich area of China (e.g HaoBTC), maybe some got destroyed to never return.

Enjoy the show over the next 3 months. At least I think we can finally ignore BFL in the whole discussion!  :)

Well the price is still increasing so gear is starting to be put online once it becomes profitable again
Right now its at 4-4.25%

I think you're with most people on that one, you saw the writing was on the wall for 2015 as machines got bigger and hotter. A lot of the gear we now host was once "home miner" gear, but they have packed in it. (It helps that we're cheaper than most people's residential rate.)

Percentage wise who are under 10 TH? Less than 10% of the total power. But we don't do any cloud mining.

Anyway... we can argue for days but it doesn't look like any of us really know how many home miners are left. Discus fish could probably tell us about IP distribution... but they won't I'm sure!

In case this is new to other folks, I found this website that seems pretty relevant here. I haven't tried to verify it's accuracy, and the projected value does seem high, if I am reading it right. Nevertheless, it seems live a worthwhile addition:

http://nextdifficulty.com/

I kinda liked the little graph, cause it clearly shows the last 7 days, which has a definite upward trend.

it is interesting but the prediction is too high  5.6% is conservative and 6.1% is the best guess and 7.7% is top end.

yesterday we had a good high number of blocks 171   which is the highest number since march when we had a 176.

today we are dropping back to 140 something

https://blockchain.info/blocks

364292 -------------------18:19

363188 ------------------- 00:03

so 105 in 18 hours and 20 min  we should do 6 x 18.= 108 +2 = 110  so we are at a 138 pace for today

daily tracking is tough

but  that is what this thread is about  tracking the diff.

we did have quite a few days in a row over 144   five to be exact, but today could break that streak.

Bitfury pool luck plummeted; nothing for 6 whole hours.
https://www.blocktrail.com/BTC/pool/bitfury/

maybe they had a meltdown :-\


they could stay offline for a while

Know the feeling.
Hope they're just trying to keep the diff down, though

edit, add: http://www.coindesk.com/bitcoin-miner-bitfury-rasies-20-million/

To bad they are such a quiet company we likely will have to speculate.  But it appears to be more then luck we can safely say at this point.   

It could be anything from scheduled maintenance to a more serious problem.   If in a day they are still having such low numbers I will go twords more serious.   

I'm not sure this time. Maybe we can go all the more low again. But we need to properly analyse it. Price is rising very swiftly. That's the thing worth noticing here.

Personally, I think someone is playing with on/off switch since a few months (hardware update or not) ... we saw that pattern so often.  They have been pushing the hashrate for the most time during the current Diff and now they are giving it a break at the end of the diff, sometime it's the reverse ... nothing at first then a big push at the end.

Well, i'm speculating here

Who would be crazy enough to shut down gear?  I think most companies greed would run them 24x7.    Turning them off is like taking a loss, I don't see the big players doing this.

I think they try and play games with the diff adjustment toward the end of the cycle.  Like HerbPean mentions, we see the same thing over and over, it can't be coincidence.

I'm sure the big players have figured out how to optimize their profits by turning some gear on and off at key times based on electricity rate and btc price.

My logical thinking would say the exact same thing as you mention but it seems someone is still doing it.

if you are a big player  on the mining side  fast growth of the network is not needed.  exactly what has happened  since the fall under 2% growth per diff adjustment works well.

It would seem that this "timing" or "gaming" of the hash rate can't work long term. Somebody (e.g. SFARDS or 21 Inc) decides to start mining, then either the network grows as a result, or somebody else has to "make room". Seems kinda like OPEC, and then a new oil producing country decides to join in.

Appears they are back up and hashing.  So was some bad luck or temporary problem it would seem.   Last 2.5 hours or so are where something kicked back on or them

they altered block size did one block at 974.5kb then looked like they crashed for 8 hours or so.  seems to be back up and now running 974.5kb blocks vs 135kb blocks

How much can we get this +% difficulty adjustment down in the next 2 days?  Hopefully under 1%!

So sad when a good conspiracy theory gets busted by something more mundane (i.e. facts).   :)

Don't worry I'm sure there are more conspiracy's to come.   We never lack those :)

Yeah looks like they are testing out software.  Oh they may have waited until today or not.  If they add huge amounts over the next 2 weeks which they may one could argue they scheduled the down time now.

July 9 was  weak  132 blocks.

so 2.5 to 3.5  seem to be closest

And BTC hit's 286 it appears.... we hit a little rocket ship that blasted it up :).  Fun to watch.

If we get this kind of price and a low difficulty chance man will this be a another week for us miners that kept mining through it.

Coins have past 291 then dropped to 284.

we have made 81 blocks so far

https://blockchain.info/blocks



we should be at 78    so not that bad.

Even though I didn't pick it, I'm happy that things dropped back down to the 2.5% increase range... for a while there it really looked like we were going to see north of 5%.  Chances are exceptionally good it'll be over 50G when it happens, but with the price of BTC at $285, my S3s will remain plugged in another couple weeks :)

I'm still hoping we can drop under 2%!  Definitely a plus the S3's(and +) can keep on churning

I will be happy if we can just stay in 2's.  If so I consider that a sucess.

The added value is very very nice suprise.   I really want to hit 300 mark and we are not to far away from it at this point.  Maybe another surge or two.

And difficulty is still moving slow... long live mining!

I'm surprised that with the btc price edging up to $300USD that we're seeing such a small diff increase, I would have thought we'd be going much higher.

Most said it would be.  And it's a nice surprise for miners.  I even believed them and got rid of some S3's, wish I would have kept them now.

We really have had a great summer on difficulty.  We will see if it continues I sure hope it does.

this was a good adjustment period while we went up say 3.5%   price went from around 265 to around 290 that is a 9% or 10 % jump

52 blocks left so figure  2 to 4 pm sat the 11th   Eastern Standard Time.

Damn, I was hoping for a slightly lower increase, and REALLY would have liked a decrease  ;D

looks like we will close at over 51 bill diff.

good luck guys

This one is not that bad, 3-4%.

The next one is going to be interesting. If the exchange rate stays where it is we could be looking at 5%+ in two weeks.

yeah 3.58% may be more like 5 to 7%

If this price holds on

I think I'm going to be pretty happy as far as this difficulty change.   To have it over 290 and +3 ish on difficulty is not bad.

I just really would like to see it break 300 in next difficulty.  It does have a chance to.

congrats.

Suchmoon should pay some time today.

Congrats to winner, so we have just passed 50m diff. with these prices , I believe we can see another + next time. Just my 2 satoshis  ;)

yeah with 290-300 we will go up.

@ the winner lets us know when suchmoon  settles out with you.  I will then close this and open the new one up.

Congrats wpt1wpt1!

Please give me a couple of hours, I'm away from my wallets at the moment.

Not to bad of a difficulty change.  And were still above 290 so  that is good.

Will be interesting to see what next change has in mind for us all.

suchmoon,

No problem I am stoked just to win. stupid looking victory dance Brag Brag etc. etc.

Congrats, that was the closest I've ever been to winning.

If you had told me 6 months ago we'd be in the middle of summer with btc over 290USD and diff changes less than +5% I wouldn't have believed you.

Congrats on your win and have a great victory dance  ;D

This is very very true.  It seemed everyone talked about a much much higher difficulty change.

I listened to a point but glad I kept most of my miners.  We will see but next difficulty I really want to hit 300, that would be very nice.

Don't wait we just hit $300 right now

$303.22USD

Literally broke through a few minutes ago U_U trading simulator chalks this one as my error lol.

I guess wish and we shall recieve!  Wow that is a great mark to hit once again.

Low difficulty change and over 300.  Time to party yet?

A little longer we need to wait for the $420 threads to come back to life
It has all the weed and smoke
(Then after that the $1000/coin Bitcoin party in Las Vegas that we delayed for a few years for a hard core party ^^)
Still $300 is on the way there and good for mining

Here you go:
