This difficulty was reduced April 19, 2015 to 47,610,564,513.  On Apr 17, 2014 the difficulty was 6,978,842,650.  That means your hash rate, from April 17, 2014 to April 19, 2015 needed to increase 6.8 times to mine the same amount of coin.  I plan on getting out WAAAAAAAAY ahead of the difficulty before the blocks halve and also have electricity rates of 3.4 cents per kWH to make the block halving much easier to bare if the price of bitcoin is the same as what it is today ($ 238.00).

Bitcoin difficulty on Apr. 17 2014 was 6,978,842,650 [BTC-e $485.58].  On Apr 19, 2015 it was 47,610,564,513 [BTC-e $220.43].  That means the difficulty rose 6.8 times more than what it was a year prior. [Your hash rate would have to be 6.8 times more than what it was this time last year to mine the same amount of coin.]

Bitcoin difficulty on Apr. 05 2014 was 6,119,726,089 [BTC-e $467.78].  On Apr 05 2015 it was 49,446,390,688 [BTC-e $257.01].  That means the difficulty rose 8.07 times more than what it was a year prior.  [Your hash rate would have to be 8.07 times more than what it was this time last year to mine the same amount of coin.]

Bitcoin difficulty on Jul 22 2013 was 31,256,961 [BTC-e $84.50].  On Jul 25 2014 it was 18,736,441,558 [BTC-e $594.47].  That means the difficulty rose 599.4 times more than what it was a year prior.  [Your hash rate would have to be 599.4 times more than what it was this time last year to mine the same amount of coin.]

Bitcoin difficulty on Jun 29 2013 was 21,335,329 [BitStamp $88.83].  On Jun 29 2014 it was 16,818,461,371 [BitStamp $599.86].  That means the difficulty rose 788.3 times more than what it was a year prior.  [Your hash rate would have to be 788.3 times more than what it was this time last year to mine the same amount of coin.]

The numbers above reveal at one time we had as much as a 788.3 times increase in difficulty over a year's time.  That number has reduced to 6.8 times more than what we had the year prior.  The amount it increases year over year is being reduced every difficulty change quite significantly.  I think now is the best time to get into mining than this time last year.  I just started myself on September 22nd last year.  By September this year, the difficulty might be around 64,000,000,000.  That would be less than 2 times what it was September of 2014.  

Like I've told others, I think I got in at the right time.  I started out with 7 TH/s September 22, 2014.  I ought to have 210 TH/s by September this year.  That would be 30 times what I started out with September a year ago.  However, the difficulty will have only come a little shy of two times year over year.  I'm hoping to have 20 times that number in September of 2016 at 4,200 TH/s.  And again, the difficulty might be 2 or 3 times what it was the year over year for September 2016 but I will have done a 20 times increase.  I'll stop for a while somewhere in between 5,000 and 10,000 TH/s to recoup all of my investment and then some.  Then start again...

If you look at the numbers below [curtesy of https://bitcoinwisdom.com/bitcoin/difficulty] you can see what I see.  For example:

On May 24, 2014 the difficulty was 10,455,720,138.  Do you honestly think it will be close to 10 times that at 100.4 Billion this coming May 24th of 2015?  I seriously doubt it.
On Jun 29, 2014 the difficulty was 16,818,461,371.  Do you honestly think it will be close to 10 times that at 160.8 Billion on June 29, 2015?  I seriously doubt it.
On Aug 31, 2014 the difficulty was 27,428,630,902.  Does one really believe it will be close to 10 times this at 270.4 Billion on August 31, 2015?  I seriously doubt it.

Yes, there is plenty of talk of the 3rd generation chips (rigs) coming out by the Summer of this year (2015).  The power efficiency and hash rate of these 3rd generation rigs remains to be seen.  Will 3rd generation rigs encourage miners who stopped mining to start back up again because of their power costs being above 15 cents per kWH?  More than likely.  Especially, if the price of bitcoin remains at the $235.00 to $335.00 level.  

If bitcoin price is higher than $335.00 by the end of November, 2015, we could definitely see more miners wanting to come back into the fray.  The only issue is will they be able to buy these 3rd generation rigs from those who will manufacture them?  The demand for power efficient 3rd generation rigs could be quite high.  The 3rd and 4th quarter of 2015 will be a very interesting time of year indeed for the miners.

I say down, it goes up. I say up, it goes down. I'm going to be more patient this time.

Ah the joys of statistical noise! I'm no better even after calculating all of the statistical variance numbers for a network seeing steady changes (and that's not what we see of course ). Still, it's fun guessing!

Well people are  renting from nicehash and westhash to mine an alt coin.  close to 7ph   7ph/338ph = 2%

We need to see how long this event lasts.  3 days would be nice. 1 week would be outstanding.

Frankly this alt coin pulling rate from btc is going to happen again and again and again. Not sure if it is good or bad in the long run.  But I am all BTC so I just rent my gear to nice or west hash and make 0.015 or more for the time being.



Oh bitmaintech announced a s4+ a very interesting price point and piece of gear. I wonder how long they will keep it around this machine represents the ending of the s-3 chip.  They managed to squeeze it down to .58 watts.  which for the s-3 chip is very good. but it is not as good as an s-5

Yes, I saw that several hours ago.

I worry for Bitmaintech when they come out with this rig several months after the S5.  It's just not good for THEIR business.  They should come out with both of them at the same time.  This way they have a better chance of selling the larger form factor with PSU included.  We may not see the 3rd generation until late August or September I'm afraid.  They will want to squeeze this out as long as possible to sell all of the S4+'s they can.  I believe they had a hard time selling all of batch two of the S4 before coming out with the S5 only a couple of months later.  At least they came out with the large form factor a little earlier than last year.  Maybe they will do better with it.

I have no need for the S4+.  I could use the boards to replace my boards in the older S4 Batch 2.  I would be willing to spend money to replace the boards in all five of my S4's.  They stand a better chance of making more money if they would do this.  I know plenty of miners with S4's who do this.  However, the PSU in the present S4 is the issue preventing them from doing this I'm sure.  Maybe they should sell the PSU with the boards as a possible upgrade kit.

I look at the current conditions as a shipwreck but I and many others are on good sturdy lifeboats waiting for rescue.  We have food water all we need to survive for the moment.  I have only new gen gear. It turns a very small profit over power cost. I hang in waiting for  a price spike (a rescue from the lifeboat) .  I have been doing this method for almost 14 months. 

Breaking even  or very small profits as price of btc has dwindled from 814 usd  in feb 2014 to current 225 in apr 2015.

They managed to squeeze it down to .58 watts.

I wasn't following this, but I think the original S4 was supposed to be undervolted to roughly that level? Then they removed that option from the firmware IIRC.

Anyway, I don't think I'll be rushing to buy the S4+, not at this price at least.

Congrats everyone on the diff drop, and the rollover should make it interesting in this round.

Yeah this is good if you have power under 7 cents and 205 volts or more for power.

I think the s4+ would have to be cut in half for price for people to consider it. Unless someone gets a bulk buy deal at an amazing price.

The only hardware floating around for now will be the stuff that is already out there being used.

Hashrates might change a little as the newest sha-256 alts come start to go full PoS. So we'll probably end around 350-360PH/s also depending on if price goes up for Bitcoin.

well I am getting paid 0.015 a th at westhash to mine my 2 avalon 4.1's I cranked them to about  2.24th about1.12 th each.  when west and nice hash go to normal I will turn down to 1.8th or about .9th each.

I thinking many smaller miners do this. to the right is page 24 of a 453 page pdf .  it is the nightly pay out sheet of a very big pool f2pool.   from 1 to 23 miners are over 20th so toss them out from page 24 to 453 miners are around 20th or less keep them in.

 page 24 has  22 miners around 20 th or 440th
 page 25 has 22 miners around  20 th or 440th    

down to page 42

it has 22 miners around  10th or 220th  

 so those pages 24 to 42 = 19 pages at 22 each or 418 miners the average is 20 + 10 + 30/2  or 15th

  that is 6.270ph  in miners from 10 to 20 ph.

from pages 43 to 66 = 24 x 22  or 528 miners  between 10 and 5 th or 7.5th  that is 3.96ph

lastly from 67 to  126 or 60 x 22 = 1328 miners between 5 and 1 th or 3th   that is  3.984 ph

so 6.27ph
    3.96ph
    3.98ph

this is 14.21 ph  is between  1th and 20th on  f2pool   and owned by around 2300 miners  all of us are small enough to be nimble and shift.

So if you are wondering how nimble and shifts of hash occur.  lots of this big 72ph pool can overclock or downclock with ease  i did from pdf pages 24 to 126

here is the transaction id


https://blockchain.info/tx/b48e3c23cf78d02c2bb124e283ecef53030345d2e9b779f61e2dfdacc39ccf7f

this is a very big pool  72 ph

https://www.f2pool.com/

but well over 14ph is in people under 20th  so this pop ups and downs will happen. due to overclock underclock variance a hot alt 256 coin etc.  real growth not really I don't see much right now.

i love these altcoin runs - i make 10-50% more renting out, and it helps keep down the bitcoin difficulty.

though im not sure what altcoins are able to have such an effect beyond that paycoin garbage. is it possible that a nicehash renter could direct the hashrate at pools for a withholding attack - would that be profitable or serve any purpose beyond stagnating the difficulty?

It has been a heck of a ride in last 24 hours.  Wish I would have started nicehash before that even.   But at least I caught some of it.

It's a nice bonus when it happens I agree.  Fun to get a little bit extra BTC.

Nothing will ever do what paycoin did the planning and prep done by zew-gaw-paycoin was very good. Details were very well thought out by them and they pulled more then 20ph from btc during the run they did.

in the sunday morning before the paycoin fork, ~14 December, the price was over 30 times higher than direct mining btc!!!
~monday was double and it slowly went down to normal prices for rentals

It's tuesday here in Canada ! Mouhahahaha

I would to pick => +1,76 - +2,00%

Thanks !

9:15 AM in Romania!
+1,01 to 1,25! hope i typed correctly!

wasn't after block 300???

right now we are at block 233!!!

Tuesday and or 300???

You guys are too early, it's not 300 blocks yet, still about 60 to go.
