Difficulty: Bitcoin Difficulty: 711,697,198,174 Estimated Next Difficulty: Adjust time: Hashrate(?): 5,079,543,675 GH/s Block Generation Time(?): Updated: Chart Explained The difficulty.The estimated next difficulty.Average block generation time of 2016 blocks.Block generation time is also known as confirmation time.Average block generation time of 1008 blocks.If grey line less than blue line, The generation time is decreasing.The more grey line is lower than blue line, the faster generation time is decreasing.After 2016 blocks generated, Bitcoin will adjust difficulty to estimated difficulty in order to keep the block generation time at 600 seconds.Difficulty History Date Difficulty Change Hash Rate Jun 17 2017 711,697,198,174 5,094,526,985 GH/s Jun 04 2017 678,760,110,083 4,858,754,124 GH/s May 23 2017 595,921,917,085 4,265,775,241 GH/s May 10 2017 559,970,892,891 4,008,427,786 GH/s Apr 27 2017 521,974,519,554 3,736,439,151 GH/s Apr 13 2017 520,808,749,422 3,728,094,244 GH/s Mar 30 2017 499,635,929,817 3,576,533,297 GH/s Mar 17 2017 475,705,205,062 3,405,230,497 GH/s Mar 03 2017 460,769,358,091 3,298,315,540 GH/s Feb 18 2017 440,779,902,287 3,155,225,442 GH/s Feb 04 2017 422,170,566,884 3,022,014,630 GH/s Jan 22 2017 392,963,262,344 2,812,940,600 GH/s Jan 10 2017 336,899,932,796 2,411,623,656 GH/s Dec 28 2016 317,688,400,354 2,274,102,150 GH/s Dec 15 2016 310,153,855,703 2,220,167,778 GH/s Dec 02 2016 286,765,766,821 2,052,749,317 GH/s Nov 18 2016 281,800,917,193 2,017,209,539 GH/s Nov 05 2016 254,620,187,304 1,822,642,296 GH/s Oct 22 2016 253,618,246,641 1,815,470,125 GH/s Oct 08 2016 258,522,748,405 1,850,577,916 GH/s Sep 25 2016 241,227,200,230 1,726,771,560 GH/s Sep 12 2016 225,832,872,179 1,616,574,667 GH/s Aug 29 2016 220,755,908,330 1,580,232,344 GH/s Aug 15 2016 217,375,482,757 1,556,034,316 GH/s Aug 02 2016 201,893,210,853 1,445,207,896 GH/s Jul 18 2016 213,492,501,108 1,528,238,850 GH/s Jul 04 2016 213,398,925,331 1,527,569,009 GH/s Jun 21 2016 209,453,158,595 1,499,324,110 GH/s Jun 08 2016 196,061,423,940 1,403,462,340 GH/s May 24 2016 199,312,067,531 1,426,731,353 GH/s May 11 2016 194,254,820,283 1,390,530,167 GH/s Apr 28 2016 178,659,257,773 1,278,892,782 GH/s Apr 14 2016 178,678,307,672 1,279,029,147 GH/s Apr 01 2016 166,851,513,283 1,194,369,655 GH/s Mar 18 2016 165,496,835,118 1,184,672,491 GH/s Mar 04 2016 158,427,203,767 1,134,066,098 GH/s Feb 19 2016 163,491,654,909 1,170,318,852 GH/s Feb 07 2016 144,116,447,847 1,031,625,717 GH/s Jan 26 2016 120,033,340,651 859,232,121 GH/s Jan 13 2016 113,354,299,801 811,421,684 GH/s Dec 31 2015 103,880,340,815 743,604,444 GH/s Dec 18 2015 93,448,670,796 668,931,642 GH/s Dec 06 2015 79,102,380,900 566,236,898 GH/s Nov 24 2015 72,722,780,643 520,569,941 GH/s Nov 11 2015 65,848,255,180 471,360,171 GH/s Oct 29 2015 62,253,982,450 445,631,364 GH/s Oct 15 2015 60,883,825,480 435,823,399 GH/s Oct 01 2015 60,813,224,039 435,318,014 GH/s Sep 17 2015 59,335,351,234 424,738,988 GH/s

Published on September 3rd, 2014 by It is not a coincidence that the value of Bitcoin increases as mining difficulty rises.bitcoin umfrageIt is also not a coincidence that the mining difficulty increases as the value of Bitcoin rises.why did bitcoin difficulty dropThere is a very tight linkage between the two.litecoin redfitTo understand why, we must first understand how mining affects the difficulty.bitcoin fund jerseyCommercial mining closely resembles regular manufacturing businesses.bitcoin 2021There are capital costs including mining hardware---ASICs (specialized mining hardware), GPUs (graphics cards), CPUs (regular computers)---and infastructure such as ventilation.bitcoin casino 777

Then there is the variable cost of electricity.The goal is to maximize profit: getting the most out of the hardware before it becomes unprofitable and then selling.Most miners sell their newly mined bitcoin immediately to recoup costs, creating market sell pressure and driving down the price.Holders usually do better in the long run by benefitting from the appreciation of bitcoins.Difficulty increases as more miners deploy more mining hardware.The bitcoin network automatically adjusts the difficulty every 2016 blocks, roughly every two weeks, so that each mined block takes about 10 minutes to find.The current seignorage reward for mining a block is 25 bitcoins.Every machine, even a weak laptop, has a shot at finding the block on a pro rata basis of its hashing power.By joining a mining pool, miners can reduce the variance of the reward similar to office workers buying a batch of lottery tickets to increase the chance of winning, while accepting a smaller reward.In a pool, if one miner finds a block, the reward is distrubed among pool members.

How and why is the bitcoin price correlated with the difficulty?Every miner looks at the cost of equipment and electricity in order to make two educated guesses.First, "How fast will the difficulty rise?"And second, "How fast will the value of Bitcoin rise?"These two numbers, impossible to know in advance, are critically important.Looking at historical rates and projecting forward provides a method for estimating these numbers.Efficient market theory says that it will eventually be the same cost to purchase a bitcoin as it will be to mine a bitcoin.Because if it’s cheaper to mine a bitcoin than to buy a bitcoin, miners will buy more hardware, burn more electricity, mine, and sell bitcoin into the market pushing the market rate down until mining is no longer profitable.If it is cheaper to buy a bitcoin, then the money that might possibly go into mining will instead purchase bitcoin pushing the market price up.Why mine at all, if efficient market theory gaurantees a profitless undertaking?

Because efficient market theory breaks down at the compressed timescales involved in Bitcoin.Rational market forces have not gone away, but they simply cannot adapt as quickly as the bitcoin ecosystem changes.If you are prepared to mine when the price rockets on speculation, and before the difficulty adjusts to compensate, there are significant profits to be made.We have all heard stories from the early bitcoin days, literally only a few years ago, when mining bitcoin with a laptop yielded a single coinbase of fifty coins.We have also heard stories of those same people turning off their computers because mining just was not worth it.I want to scream knowing that those same bitcoins are now worth a combined total of tens of thousands of dollars.But those folks were operating logically.The cost of electricity exceeded the value of the bitcoins at the time.It was better to buy bitcoin on the open market with the same money that would have been spent on electricity, although few bought.So what changed from those easy, breezy, laptop mining days?

The difficulty has changed.By design, half of all the bitcoins that will ever be mined were mined in the first four years.Does this mean they were easier to find in the beginning?Yes, but not because they were just laying scattered around somewhere.The careful and considered design of the software by its creator, Satoshi Nakamoto, made them easier to mine at the beginning and harder as more miners join the party.These details are controlled not by elite bureaucrats, but by the bitcoin software, and while software can easily be changed, it is necessary that all miners use software that follows the same rules.Since miners are invested in the current ruleset, it will be nearly impossible to change the protocol by getting most of the miners to switch software.Now fewer bitcoins are left to mine, and the reduced number of bitcoins are distributed proportionately among the miners based on the resources they marshal for mining.Add more miners and each miner gets fewer bitcoins until some miners drop out because their mining equipment is not as efficient, or their electricity costs are too high.
