Bitcoin Difficulty Chart | Bitcoin Difficulty Prediction

Bitcoin difficulty is an estimate about how difficult it is to mine (find) a new bitcoin block. Bitcoin mining has two main purposes. One is adding transactions to the bitcoin block chain. The other purpose is to create new bitcoins. The total number of bitcoins that will ever be mined is limited to 21 million. Moreover, the bitcoin protocol determines a time horizon over which the bitcoins will be created. This is done to limit the supply of bitcoins . A new block is mined every 10 minutes. The number of bitcoins in one block is currently BTC 25 and is halved every 210,000 blocks or approximately every four years. If everybody could easily mine new bitcoins, inflation would be the result. Bitcoin difficulty exists to ensure a limited bitcoin supply. This does not mean there could be no inflation for bitcoin. Activities like bitcoin lending can increase the bitcoin money supply. But the main underlying driver of money supply remains the monetary base which is represented by the number of mined bitcoins. Therefore bitcoin difficulty is important to maintain the bitcoin purchasing power . Bitcoin mining gets more difficult with an increasing computing power in the network. The protocol always makes sure the pre-defined trajectory of bitcoin creation is kept. The computing power is measured in hashes per second. To understand what that means, the process of mining needs to be explained in further detail. When a computer mines bitcoins, it tries to calculate a hash which is the block's header. The hash starts with a certain number of zeros. The number of zeros is defined by the target. The target is a 256-bit number and is therefore extremely long. All bitcoin clients know the target. It gets more difficult to mine bitcoins, the more leading zeros the hash has got. At the Continue reading >>

What Is The Mining Difficulty?

What Is The Mining Difficulty?

JP Buntinx April 14, 2017 Education , FAQ Cryptocurrency enthusiasts will often hear how miners have to provide more powerful hardware to keep up with the mining difficulty. To some people, this may sound strange, as the mining difficulty doesnt become more difficult in the traditional sense. The difficulty is a unit of measurement designed to indicate how difficult it is to find a hash below the given target, either on the bitcoin network or any other currency that can be mined through proof-of-work. Mining Difficulty is An Interesting Concept Everyone who ever dreams of mining bitcoin or another cryptocurrency have somewhat of a learning curve to go through. One aspect of mining cryptocurrency revolves around the current difficulty. Although this difficulty does not change the mining process per se you need hardware, electricity, software, and a mining pool the process becomes more difficult and complex under the hood. To be more specific, the mining difficulty is determined by several factors. First of all, there is a global block difficulty, which forces valid blocks to have a hash below this target. Second, there is the factor of how many people are actively mining on the network alongside oneself. Last but not least, it is possible the mining pool itself uses a share difficulty setting for mining a particular cryptocurrency. In the world of bitcoin, the mining difficulty automatically adjusts every 2,016 blocks on the network. Depending on how many people were mining and their combined hashpower and the time it took to find those 2,016 blocks. The difficulty will go up or down. As the difficulty increases, miners need more powerful hardware to accommodate for this change. This is why CPU, GPU, and FPGA mining became obsolete once ASIC hardware was created by manu Continue reading >>

Mining Incentives Part 1 The Economics Of The Difficulty Adjustment

Mining Incentives Part 1 The Economics Of The Difficulty Adjustment

Abstract: This piece contrasts mining economics between Bitcoin and traditional resource mining. We look at how the difficulty adjustment can impact profitability in the mining industry and some potentially perverse incentives. Mining is the random process by which new Bitcoin blocks are found, such that transactions are confirmed. This is a necessarily competitive and energy intensive process. In order to ensure a smooth and reliable network, every two weeks, based on how many blocks were mined in the period, the mining difficulty adjusts. There is an average target interval between blocks of 10 minutes. A two week period is split into 2016 sections of 10 minutes. If more than 2016 blocks were mined in a two week period, mining becomes more difficult, such that if the hashrate remains constant, blocks are expected to be found every 10 minutes in the next two week period. If fewer than 2016 blocks were mined in a two week period, mining becomes less difficult, such that if the hashrate remains constant, blocks are expected to be found every 10 minutes in the next two week period. The maximum adjustment in any one period is a factor of 4 (i.e. a range of 25% to 400% of the old difficulty). The below chart shows the difficulty adjustments (red line) and the calculated rolling two week hashrate estimate (green line), over the last 2 months. Mining Equilibrium and the Misconception This Means Miners Cannot Make Profits In theory, the difficulty adjustment keeps the system in check, in an equilibrium position, when external inputs change. For example consider the following scenario of a sudden increase in the Bitcoin price: Mining profitability increases, since miners are rewarded in Bitcoin More miners join the network to take advantage of higher profit margins and there a Continue reading >>

Do Bitcoin Mining Energy Costs Influence Its Price?

Do Bitcoin Mining Energy Costs Influence Its Price?

Do Bitcoin Mining Energy Costs Influence Its Price? By Rakesh Sharma | November 26, 2017 5:46 AM EST Hydropower: The Key to Bitcoin Mining in the Future? Several recent reports have drawn attention to the massive amounts of energy used for bitcoin mining operations. The statistics are staggering. According to the Digiconomist website , a bitcoin country would rank 64th in the world for overall energy usage. Bitcoins annual energy consumption is estimated to be 30 TWh. (Wikipedia defines one terawatt hour as being equal to a sustained power of 114 megawatts for a period of one year). On a more granular level, approximately 10 U.S. households can be powered for a single day using electricity required for a single bitcoin transaction. (See also: Is Bitcoin Mining Still Profitable? ) Energy accounts for between 90% to 95% of bitcoin mining costs and plays an extremely critical role in determining profitability for thecryptocurrencys miners. In turn, profitability is important to attract more miners and grow the bitcoin mining ecosystem as demand for bitcoin spirals. (See also: How Does Bitcoin Mining Work? ) Does the increased cost of bitcoin translate to higher future prices? The Relationship Between Mining Energy Costs And Bitcoin Price Energy usage for miners is contingent upon several factors, from availability of cheap and plentiful power to energy-efficient hardware to the difficulty of problems being solved by machines to earn bitcoin rewards. For example, a difficult problem is computation-intensive (versus an easy problem) and, subsequently, will need additional energy resources for solving. A Forbes post last year suggested that bitcoins seigniorage (or the difference in its cost of production and overall value) will become unviable, unless the mining process bec Continue reading >>

Exchange Rate - Is There Empirical Data About A Relationship Between Bitcoin Price And Difficulty? - Bitcoin Stack Exchange

Exchange Rate - Is There Empirical Data About A Relationship Between Bitcoin Price And Difficulty? - Bitcoin Stack Exchange

Is there empirical data about a relationship between bitcoin price and difficulty? There have been claims that Bitcoin price and difficulty correspond. Is there empirical data to support or refute this? This doesn't answer your question, but: The logic for why this happens is not obvious. When the price of Bitcoins is higher, people are more likely to mine, especially people whose costs are close to their expected proceeds. The greater number of miners drives up the difficulty. Price drives difficulty, not the other way around. (If this is correct, it should be empirically verifiable -- which rises first?) David Schwartz Sep 2 '11 at 8:19 I will second David on this, we have seen this recently with the price drop being followed by a decrease in network hashrate. Alex Waters Sep 2 '11 at 9:08 @Alex Waters: Well that's an answer then, isn't it? If a price drop is seen to be followed by a decrease in hash rate (which obviously will lead to a difficulty drop) then that's empirical data relating price to difficulty. David Schwartz Sep 2 '11 at 9:36 If you look at the network hash rate , you'll notice that it fell off after the Bitcoin exchange rate dropped. This leads to the conclusion that price drives difficulty. A drop in price caused a drop in difficulty. I have noticed this same correlation on another occasion; about two months ago. Also, the reverse is probably true. When the price soared to $30+; the network hash rate accelerated greatly. The higher prices clearly attracted miners. please check out my website bitcoinx.com/charts where you have both difficulty and price in one diagram. Mining profitability is available, too. kermit Sep 29 '11 at 10:11 @phelix - Just what I was looking for. How did you compile the data for these charts?

Difficulty - Bitcoin Wiki

Difficulty - Bitcoin Wiki

Difficulty is a measure of how difficult it is to find a hash below a given target. The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this target.Mining pools also have a pool-specific share difficulty setting a lower limit for shares. How often does the network difficulty change? difficulty = difficulty_1_target / current_target difficulty_1_target can be different for various ways to measure difficulty.Traditionally, it represents a hash where the leading 32 bits are zero and the rest are one (this is known as "pool difficulty" or "pdiff").The Bitcoin protocol represents targets as a custom floating point type with limited precision; as a result, Bitcoin clients often approximate difficulty based on this (this is known as "bdiff"). Each block stores a packed representation (called "Bits") for its actual hexadecimal target . The target can be derived from it via a predefined formula. For example, if the packed target in the block is 0x1b0404cb, the hexadecimal target is 0x0404cb * 2**(8*(0x1b - 3)) = 0x00000000000404CB000000000000000000000000000000000000000000000000 Note that the 0x0404cb value is a signed value in this format. The largest legal value for this field is 0x7fffff. To make a larger value you must shift it down one full byte. Also 0x008000 is the smallest positive valid value. How is difficulty calculated? What is the difference between bdiff and pdiff? The highest possible target (difficulty 1) is defined as 0x1d00ffff, which gives us a hex target of 0x00ffff * 2**(8*(0x1d - 3)) = 0x00000000FFFF0000000000000000000000000000000000000000000000000000 It should be noted that pooled mining often uses non-truncated targets, which puts "pool difficulty 1" at 0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF S Continue reading >>

The Price Difficulty Ratio Chart

The Price Difficulty Ratio Chart

The relationship between price and mining difficulty This forum post provides an excellent analysis of the relationship betweenthe bitcoin market exchange rate and mining difficulty.The rule of thumb has been that difficulty trails price, with a several week lag. Now we have data over a long enough period of time where a chart can be made and it clearly shows this rule as being fairly accurate. For those considering entering mining or adding mining capacity, the primary risk is that the difficulty will increase faster than the market exchange rate. The above chart shows that right now is one of the better times to be mining andmost miners will agree wth that sentiment. Thepicture could change dramatically, however, with the next difficulty adjustment. The barriers to entry for mining are dropping thanks tonew innovations,better software, better guides and a larger community involved in mining. Additional upside remains thanks to the increased market exchange rate so the primary contraints will likely be access to an adequate supply of graphics cards. This is Bitcoin minings Malthusian check as at some point this growth rate will exceed AMDs capacity to produce the cards, regardless of the price. Additional unkowns inlcude an if and/or when ASIC or FPGA designs might appear on the scene. One mining innovator reportedly has tens of Ghash/s of capacity from these low-powered albeit expensive, custom designs. Once GPU supplies are constrained though, these will likely be where the next Thash/s of capacity will come from. Longer term, the first 50% decrease in the mining reward (from 50 BTC to 25 BTC) is about twenty months away. Any mining configurations that are even close to not returning at least a significant profit prior to that point will likely be taken out of servi Continue reading >>

Expected Bitcoin Difficulty In 2018

Expected Bitcoin Difficulty In 2018

There are lots of videos and articles on what Bitcoin difficulty is, and lots of charts on how it's changed over the past couple of years. But this isn't really helpful if you're thinking about investing in cloud mining, or maybe even buying your own mining rig. This guide has our thoughts on what will effect Bitcoin difficulty over 2018. We posted a guide on Genesis Mining profitability for September 2017, and in this we assumed that each time Bitcoin mining difficulty doubles - the value of it also doubles. This guide explains why. So let's start by looking at how Bitcoin difficulty has changed every 4 months for the past 3 years: *Values taken from: Looking at the Blockchain chart above for the past 2 years, it definitely looks exponential; e.g. it doubles at the same rate every 4 months. But the figures for the past 3 years don't do that. In 2015 it took around 11 months for the difficulty to double, in early 2016 around 6 months, in late 2016 around 8 months - and then in 2017 between 5-6 months. What we're suggesting is that the rate the Bitcoin difficulty is increasing is not fixed. Right now, in September 2017, Bitcoin is very popular, with thousands of new investors and miners every day. So a sudden increase in difficulty would seem to make sense - as there are lots more transactions being sent, and lots more people mining it. The drop in difficulty in August 2017 is a good identifier for this, where because lots of miners moved over to Bitcoin Cash (as it was more profitable at the time), transactions were taking longer to process - and so the difficulty was decreased. If you were a miner running a large setup, and Bitcoin mining were to no longer be profitable, then you'd likely start mining something else that was. This would decrease the difficulty for eve Continue reading >>

Bitcoin Difficulty, Bitcoin News, Reviews And Help

Many of us have been raised on cash and debit cards, so introducing a new currency into our lives may seem pointless. However, theres no denying the impact that Bitcoin has made, and with new sites such as bestcryptocurrencyexchanges.net popping up online its easy to see why its becoming one of the most recognised digital currency in recent years. The reason why Bitcoin has become so popular is due to the benefits it offers. So, if youre currently sat on the fence as to whether you should adopt this currency or not, then why not consider the following benefits. Sure, it may require some changes, but this is the case for anything revolutionary. Its Designed for the Internet Generation One of the reasons Bitcoin has gained traction in the world of finance is because its designed for a core userbase, those who use the Internet. You may consider this to be a limitation, but when you consider that over 3 billion people use the Internet daily, it makes for a large capture area. One of the many worries for online users is the use of credit and debit cards. While steps are taken to reduce fraud, Bitcoin just offers that extra sense of security thanks to the encryption process it uses. The currency has proved to be such a hit online, that many users state that they may not even be using a bank account in the future. The more suspicious of us may think that people want to hide their payment history because they have something to hide, and in some instances, this can be true. However, many online users wish to remain anonymous, as they feel the experience is safer. While there can be some instances when a person does have to disclose certain details, for the most part, Bitcoin allows for a completely discreet presence when making purchases online. While final transactions are ava Continue reading >>

Bitcoin Price Analysis - Crucial Week Ahead

Bitcoin Price Analysis - Crucial Week Ahead

Bitcoin Price Analysis - Crucial week ahead Josh Olszewicz , 29 Dec 2017 - Bitcoin , Opinion , Price Analysis Bitcoin ( BTC ) has been wide-ranging over the past week after a strong pullback. The market cap now stands at US$235 billion on US$6.46 billion in volume over the past 24 hours. Volume has slowed broadly amongst the cryptocurrency markets, which is most likely due the holiday season. BTC transactions per day have declined since the peak around 490,000. This trend has been matched through Ethereum ( ETH ), Bitcoin Cash ( BCH ), and Litecoin ( LTC ). ETH continues to process the highest number of transactions per day, almost double that of BTC. However, the average value of a BTC transaction is over 10x greater than ETH (not shown below). There are currently 175,00 unconfirmed transactions in the bitcoin mempool, down from over 250,000 just a few days ago. Transactions usually see an uptick during downwards price movements, as was the case from the 17th to the 22nd of December. This only compounded the problem of the existing backlog. Spam transactions also continue to plague the network. One such spam attack was caught live and recorded. SegWit, which reduces the size of each transaction and therefore makes the transaction cheaper, continues to have around 10% adoption. Key bottlenecks in the ecosystem like the major exchanges continue to develop, or ignore, SegWit integration. Coinbase/GDAX has promised SegWit addresses sometime in 2018. Currently, SegWit uses the P2SH address format which is compatible with older clients. A BIP, first introduced on the 20th of March, is gaining traction to move SegWit towards native addresses. BIP 173 , created by Peter Wuille and Greg Maxwell of Blockstream, introduces the Bech32 address format which is more efficient and se Continue reading >>

Bitcoin Difficulty Increase August 9th,2017

Bitcoin difficulty increase August 9th,2017 BTC chain is due its routine difficulty increase and judging by data from: Bitcoin Difficulty hashrate chart and accurate estimated next difficulty.bitcoinwisdom.com We can expect to see difficulty increase of ~8%. Such change happens every 2016 blocks, what makes this happening interesting is that at the same time price of BCH (Bitcoin cash chain) is rising and its difficulty is decreasing dramatically due to adjustments happening to account for difficulty inherited from original BTC chain during the split. There is a chance for BCH chain to become more profitable temporarily, hence attracting miners from BTC chain to move their hash power over to it. If this happens we might see significant increases in BTC validation times given that enough hashpower moves to BCH chain. Above events are not likely to happen, but never the less BTC chain needs all hashing power it can get as SegWit is not active yet (you can keep track of it over at ) and its mempool is being spammed (as this article is being typed) resulting in network clogging.

Explain It Like I'm Five - Bitcoin Mining Difficulty Level | Newsbtc

The Bitcoin difficulty level recently increased by 7.09% recently. What is difficulty level and why is is important? Bitcoin is probably the first decentralized, distributed open source digital currency protocol to gain massive adoption. No sooner the concept of digital currency was introduced by Satoshi Nakamoto in his whitepaper, it garnered a lot of interest from computer scientists and cryptographers. Some of these people had already tried creating a digital currency system with limited success. But Bitcoin offered a solution to many problems that were faced by the researchers until then. These very solutions were the reason for Bitcoin to become one of the widely adopted digital currencies in the world till date. The main intention behind the creation of Bitcoin was to empower individuals by providing them with an alternative way to conduct peer to peer transaction over the internet without having to go through the middle men or a trusted third party like banking and financial institution. In order to fulfill its purpose, the digital currency protocol has to meetcertain criteria. Apart from being scarce, fungible and highly divisible, it is important for bitcoin network to maintain consistency. Consistency of the network takes a special place because of its distributed nature. We all know that Bitcoin is an open source, decentralized digital currency where the miners, who are part of the Bitcoin community contribute processing power to discover new blocks and confirm transactions over the network. This is done by comparing the transaction ids with the existing record on the blockchain and inserting the new transaction records into fresh blocks. Technically, the time taken by a miner or a mining pool to discover a new block is directly proportional to the total pro Continue reading >>

7 Reasons Bitcoin Mining Is Not Profitable Or Worth It In 2017

7 Reasons Bitcoin Mining Is Not Profitable Or Worth It In 2017

Jordan Tuwiner Last updated June 13, 2017 The early days of Bitcoin mining are often described as a gold rush. Satoshi Nakomotos invention of Bitcoin, a peer-to-peer electronic cash system, opened up an entirely new frontier, not just of freedom but of occasionally outrageous profits. Those with a strong interest in such things, namely cypherpunks, cryptographers, technically-minded libertarians and assorted hackers, were first to stake their claim. But is there still gold in them thar hills? Bitcoin mining has grown from a handful of early enthusiasts into a cottage industry, into a specialized industrial-level venture. The easy money was scooped out a long time ago and what remains is buried under the cryptographic equivalent of tons of hard rock. Only those with specialised, high-powered machinery are able to profitably extract bitcoins nowadays. While mining is still technically possible for anyone, those with underpowered setups will find more money is spent on electricity than is generated through mining. In other words, mining wont be profitable at a small scale unless you have access to free or really cheap electriciy. Well explain this situation in depth but first, you need to know a few basic technical terms from the world of Bitcoin mining: A group of Bitcoin transactions, chosen from the mempool (the list of all currently pending transactions) and recorded by a miner into the ever-growing record of blocks known as the blockchain. A new block is created on average every ten minutes. This is the cryptographic work which miners perform in order to find the solution which allows them to define a new block. PoW hashing ensures the proper function of the Bitcoin blockchain. Miners compete to solve a cryptographic puzzle, known as a hash. There are no shortcuts in Continue reading >>
