That's why it makes far more sense to eliminate the fiat exchange rates and calculate profits based solely on bitcoins spent to purchase the equiment and bitcoins generated by the equipment. A Jalapenos pre-order purchased for 25 btc needs to generate 25 btc to break even.
That's if you have free electricity. Otherwise you need to add a fiat part.

It will be quite a few months from now before difficulty rises enough to make electricity costs a significant portion of the profit equation. So I'll rephrase my point... A Jalapenos pre-order purchased for 25 btc needs to generate more than 25 btc to break even.

It ended up being 12153412 or 8.64% up. First time single-digit increase in a long time.
Amazing.. Well I guess it wouldn't hurt to put a larger spread on my chart.. good call.

Hello, I am waiting on a BFL ASIC that hopefully will arrive some time this summer. I am told end of July is likely. I would like to find out if there is any calculator out there that can make a reasonable prediction of the expected bitcoin network difficulty some time into the future using existing data about the network growth rate. What difficulty can be expected 1st of august, 2013?
check my sig about difficulty going to 1 billion

check my sig about difficulty going to 1 billion Are you referring to the organiofcorti link in your sig? Since all of the assumptions it uses are wrong, it is essentially invalid? 1. Assumptions Updated information plus my current guesses and estimates:
Arrivals are constant. Rather than modelling arrival times, I'm assuming a constant rate of hashes per second added to the network for each of the batches. Batch 1: COMPLETE. (I know it's not quite, but near enough for this analysis). Batch 2: 600 of 67 Ghps units delivered from 1st May to 31st May. Batch 3: 500 of an even mix of 67 and 85 Ghps units, delivered from 1st June to 30th June. BFL delivers 2000 Ghps per day (~35 SC Singles per day) from 15th May to 31st July. ASICMiner delivers 1.15 Thps per day for a total of 100Thps until 31st July.
Batch 2, almost no units delivered to date as of 5/26/2013 (may 26th); Batch 2 assumption wrong Batch 3: It's almost June 1st, batch 2 is barely trickling out, no word on batch 3 plans, Batch 3 assumption basically wrong. BFL Delivers 2000 Ghps per day: Lol. Not even a single SC single has gone out. BFL assumption way way way wrong. ASICMiner delivers 1.15Thps per day: Uhm, again, not even close. Peaked at 23TH, currently down to about 18TH, definitely not adding > 1TH per day. Every assumption is wrong, so all calculations based on those assumptions must be wrong as well, so why would you reference that? Will difficulty go to a billion? Hell yeah, but not that way.

calm your dickz gents. making 2.8 mils worth of asics costs money, and requires logistics, not to mention information. diy chips need to be tested. that takes time shipping takes time, customs takes time c

I obtained the historic data from 50btc.com, an excellent and very easy to use mining pool.
I plugged numbers from 50btc.com into a spreadsheet and came up with this prediction graph using avg change in difficulty for last 10 periods to predict future changes. http://db.tt/LIOIvUbWnot sure how to insert image here, just providing a link. If these predictions hold up we can expect about 50m by the end of summer and close to 250m by end of the year. Coincidentally, I am projecting the same December difficulty as your graph. However, my predictions were determined by using guesses as to when new hash rates will show up on the network. You can see the spreadsheet here. And the spreadsheet is explained here.

This is past data for mining difficulty:
Date % Increase Difficulty
23-Jan-13 8.64% 2,968,775 08-Jan-13 8.64% 3,249,550 05-Feb-13 10.33% 3,275,465 18-Feb-13 11.47% 3,651,012 01-Mar-13 19.63% 4,367,876 14-Mar-13 10.98% 4,847,647 24-Mar-13 38.13% 6,695,826 05-Apr-13 14.59% 7,673,000 30-Apr-13 12.28% 10,076,293 14-May-13 11.03% 11,187,257
If difficulty increases at 15% per two weeks at next increase then at End July difficulty will be 22,501,570. If you have a Jalapeno arriving at end-July your total estimated profit would be $1,100, if you run the unit 24/7 till end 2014 year.
28-May-13 15% 12,865,346 11-Jun-13 15% 14,795,147 25-Jun-13 15% 17,014,419 09-Jul-13 15% 19,566,582 23-Jul-13 15% 22,501,570 06-Aug-13 15% 25,876,805
If difficulty increases at 18% per two weeks then at End July difficulty will be 25,593,734. If you have a Jalapeno arriving at end-July you will possibly make $750 profit, if you run the unit 24/7 till end 2014 year. At $120 per BTC your break-even date of arrival is 29th Oct, and if it arrives after this date you will make a loss. At $100 per BTC your break-even date of arrival is 15th Oct, and if it arrives after this date you will make a loss.
28-May-13 18% 13,200,963 11-Jun-13 18% 15,577,137 25-Jun-13 18% 18,381,021 09-Jul-13 18% 21,689,605 23-Jul-13 18% 25,593,734 06-Aug-13 18% 30,200,606 20-Aug-13 18% 35,636,715 03-Sep-13 18% 42,051,324 17-Sep-13 18% 49,620,562 01-Oct-13 18% 58,552,263 15-Oct-13 18% 69,091,671 29-Oct-13 18% 81,528,172 12-Nov-13 18% 96,203,242
With the present sales of ASIC chips in bulk from a competitor, Avalon, in lots of ten thousand to distributors, new miner units could reach retail customers by late July. If so this extra estimated 84 TH/s, at around $2.8 million in chip value, could have an enormous impact on mining output and difficulty levels thereafter.
Lets hope Butterfly Labs Inc. deliver as promised, and you are not one of the unlucky ones that will be mining just to cover their payment to Butterfly labs.
Good luck.
ripple, your numbers are off because you are assuming it takes exactly two weeks between difficulty adjustments at the same time difficulty is going up 15-18%. If difficulty does go up that fast, the adjustment will occur 15-18% faster than two weeks. If 2016 blocks are found faster than every two weeks, the difficulty goes up.

Though it's still too early for the next prediction, the next increase will occur in 10.2 days with difficulty jumping to 14171852. The numbers are usually closer to the mark 3-4 days before the change.
In any case, changes occurred recently with about 10-day intervals.

Difficulty prediction seems to have stabilised somewhat. Next difficulty will be around 14,144,505 in 6.3 days. Not much off ripple's 15% prediction chart.

![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fbitcoin.sipa.be%2Fgrowth.png&t=665&c=k5i_NFIf8Ti17w) Look at the 30 day average: Before March, the network was averaging 0.5% at most per day, which is only 6-7% growth over 2 weeks, not 18%. Now, we're sitting at maybe 1.2% per day since March/April? That actually is close to 18% every 2 weeks.

If this is a 'game' of predicting next diff, I would say... 12%.

Well, no, it's not a "game" or even a "guessing game". It's a prediction based on past results and future not-unknown variables.

It's not really work or art, are you sure it's not a game? I suppose this does effect our livelihood, maybe it is work. This is past data for mining difficulty:
Date % Increase Difficulty
23-Jan-13 8.64% 2,968,775 08-Jan-13 8.64% 3,249,550 05-Feb-13 10.33% 3,275,465 18-Feb-13 11.47% 3,651,012 01-Mar-13 19.63% 4,367,876 14-Mar-13 10.98% 4,847,647 24-Mar-13 38.13% 6,695,826 05-Apr-13 14.59% 7,673,000 30-Apr-13 12.28% 10,076,293 14-May-13 11.03% 11,187,257
My list shows different percentages for some of those dates.. For instance 1-23-13 is -8.64 and 1-8 is 9.06%. Oh and you're missing 4/17

i think we should consider some % of GPU going to ebay at this time i think 70% power is from gpu wchich will be unprofitable in few months. people will sell rigs.

' People will only sell rigs when GPU is overshadowed by ASIC, which will only happen when ASIC occurs en masse, which will make the loss of GPUs likely less significant. I wouldn't expect 70% of the current network to be GPUs. Currently the network is on a big high, but its looking like there is about 120TH online. Roughly 30TH of that is ASICMiner (asicminercharts.com), which is already 25%. 21TH is Batch 1 Avalons, If we assume 25% of Batch 2 Avalons are online today thats another 10TH (may be more), we're already at 50% of the network being ASICs. Then there are FPGAs, which I'll just guess at 10%, so GPU is likely closer to 40% of the network. I'm guessing most GPUs will start to go offline as difficulty passes 45Million depending on efficiency, and BTC value, at which point GPU would only comprise ~10% of the total network.

So much bullshit... The only way to predict the difficulty is to have detailed information about each of the ASIC vendors' order books, about their production pipeline, and near-term plans. Here include the self-mining ASIC manufacturers.
Nobody knows all this, therefore nobody can predict the difficulty. The best you can get is to look at the price trend, and expect similar trend in difficulty to follow within 4-8 weeks. Of course you have to account for technology leaps like the one we are going through right now.
