Bitcoin is a worldwide cryptocurrency and digital payment system  :3 called the first decentralized digital currency , as the system works without a central repository or single administrator.  :1  It was invented by an unknown person or group of people under the name Satoshi Nakamoto  and released as open-source software in 2009.  The system is peer-to-peer , and transactions take place between users directly, without an intermediary.  :4 These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain . Bitcoins are created as a reward for a process known as mining . They can be exchanged for other currencies,  products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.  Bitcoin can also be held as an investment. According to research produced by Cambridge University in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.  The word bitcoin first occurred and was defined in the white paper  that was published on 31 October 2008.  It is a compound of the words bit and coin .  The white paper frequently uses the shorter coin.  There is no uniform convention for bitcoin capitalization. Some sources use Bitcoin, capitalized, to Continue reading >>
Controlled Supply - Bitcoin Wiki
A fixed money supply, or a supply altered only in accord with objective and calculable criteria, is a necessary condition to a meaningful just price of money.  Fr. Bernard W. Dempsey, S.J. (1903-1960) In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The monetary base is controlled by a central bank. In the United States, the Fed increases the monetary base by issuing currency, increasing the amount banks have on reserve or by a process called Quantitative Easing . In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless. Bitcoins are created each time a user discovers a new block .The rate of block creation is adjusted every 2016 blocks to aim for a constant two week adjustment period (equivalent to 6 per hour.) The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every 210,000 blocks, or approximately four years. The result is that the number of bitcoins in existence is not expected to exceed 21 million.  Speculated justifications for the unintuitive value "21 million" are that it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number. Satoshi has never really justified or explained many of these constan Continue reading >>
Here's Your Simple Guide To The Bitcoin Halving
Here's your simple guide to the bitcoin halving Bitcoin price over the past 3 months, via WinkDex. On Saturday, July 9, around 1:30pm EST, the bitcoin halving will occur. What the heck is the bitcoin halving? In simplest terms, for only the second time in the digital currencys history, the reward that bitcoin miners receive will be cut in half. To get more in depth: All bitcoin transactions are recorded on the bitcoin blockchain, a public, decentralized, permissionless ledger . The transactions are recorded in bundles, called blocks, by miners who receive a small reward in bitcoin for mining. This process creates new bitcoins. Miners currently earn 25 bitcoins per blockat the current bitcoin price, thats $16,175. But beginning with the mining of the 420,000th block, which is set to happen on Saturday, the reward will go down to 12.5 bitcoins rewarded per block mined. This will reduce the creation of new bitcoins from 9% down to about 4% per year. Its an event that people in the bitcoin world have been anticipating for months with great excitementbut also uncertainty. So, what does this mean for you, Yahoo Finance reader, and for the bitcoin market? If you dont own any bitcoin, perhaps nothing at all. But there are signs that the halving could have a major impact on the price. And if it brings the price on another big ride, this could be the right time to get in. Consequently, some experts predict the opposite: that the halving will be an exit event when many speculators get out. The last time the mining reward was halved, after 210,000 blocks, was on November 28, 2012. The price did nothing significant that day, then saw a slow increase in the weeks that followed, part of a run to the highest price bitcoin has ever seen, above $1,200 one year later. But the post-halvin Continue reading >>
The Halvening! Bitcoin Halving For Rocket Lovers
In the Bitcoin network, user transactions are grouped in blocks and recorded to a digital public ledger called a blockchain . Miners are in charge of this task, and receive a mining reward in the form of bitcoins for each block recorded. The amount of bitcoins rewarded for each block decreases with time: it is halved every 4 years . This event, the moment when the mining reward is divided by 2, is commonly called "Bitcoin halving". Other denominations are used: "reward drop", "reward halving", or simply "the halving" or "the Halvening" which is a popular meme among bitcoiners. When Bitcoin was created in 2009 , the initial reward was 50 bitcoins. In november 2012, it dropped to 25btc after the first halving. The second halving will take place in July 2016, decreasing the reward to 12.5btc. Read more... As any freely traded asset, Bitcoin price depends solely on demand and supply. The evolution of bitcoins supply is hard coded and is known to everyone, so it all depends on the evolution of demand. Bitcoin being a very young currency with much room to grow in use and value, I would personally bet on a price increase. How much? When? It remains 100% unpredictable. One thing is certain though: at the time of Halving, the supply reduction will already be priced in the exchange rate, thanks to market anticipation. So don't expect a big price movement on Halving Day. Note that other examples of halvings are available for comparison. The first Bitcoin halving occurred on the 28th of November 2012 . On that day the price went up +1.7%, a negligible move. However the preceding and following months showed continued growth and led to the famous early-2013 rally (from 13$ to 260$ in 4 months). More recently, the Litecoin, a Bitcoin clone, passed its first halving on August 25th, 20 Continue reading >>
Bitcoin Is At An All-time High, But Is Itabout To Self-destruct?
Bitcoin Is At An All-Time High, But Is ItAbout To Self-Destruct? The bitcoin price has been on a tear recently, more than doubling to about $2,900 over the last three months. (It didn't hurt that Sunday, thepopular Tim Ferriss podcast released a two-and-a-half-hour episode on the subject.) But its meteoric rise belies a fact apparent to anyone active in the space: The bitcoin community is at war with itself and at greater risk of splitting apart than ever in its history. Already, the impasse has been a drag on its value. The power struggle over the seemingly simple question of how to upgrade the network to handle more transactions is pushing fees so much higher that, for certain types of transactions, bitcoin is nearly unusable. Transactions that should take 10 minutes are taking days or not going through at all , and the average fee costs $4.75 a negative development for a network whose proponents once touted the fact that it was cheaper than Visa. Even more foreboding is the fact that, even as new money flows into crypto assets, businesses are pivoting away from bitcoin to build on other blockchains. That means countless transactions that could be processed with bitcoin, pushing up its price, will now take place on other blockchains, instead boosting their prices. Accelerating that trend is the fact that non-blockchain companies are now creating their own cryptocurrencies but not on bitcoin. For instance, Kik, which plans to launch a new cryptocurrency called Kin , is building it on Ethereum. The factors above combined with the full speculative frenzy in non-bitcoin tokens and the civil war in bitcoin finally pushed its market cap as a percentage of all cryptocurrencies below 50% for the first time a few weeks ago; for years it had been at 80-90%. It hasnt recovered Continue reading >>
What Is The Bitcoin Mining Block Reward?
The Bitcoin block reward refers to the new bitcoins distributed by the network to miners for each successfully solved block. Satoshi Nakamoto, Bitcoins creator, set the block reward schedule when he created Bitcoin. It is one of Bitcoins central rules and cannot be changed without agreement between the entire Bitcoin network. The block reward started at 50 BTC in block #1 and halves every 210,000 blocks. This means every block up until block #210,000 rewards 50 BTC, while block 210,001 rewards 25. Since blocks are mined on average every 10 minutes, 144 blocks are mined per day on average. At 144 blocks per day, 210,000 blocks take on average four years to mine. Total circulation will be 21,000,000 coins. Itll be distributed to network nodes when they make blocks, with the amount cut in half every 4 years. first 4 years: 10,500,000 coins next 4 years: 5,250,000 coins next 4 years: 2,625,000 coins next 4 years: 1,312,500 coins etc - Satoshi Nakamoto The block reward is the only way that new bitcoins are created on the network. Satoshi explained this in an early email post in 2009: Coins have to get initially distributed somehow, and a constant rate seems likethe best formula. The block reward creates an incentive for miners to add hash power to the network. The block reward is what miners try to get using their ASICs, which make up the entirety of the Bitcoin network hash rate. ASICs are expensive, and have high electricity costs . Miners are profitable when their hardware and electricity costs to mine one bitcoin are lower than the price of one bitcoin. This means miners can mine bitcoins and sell them for a profit. The more hash power a miner or mining pool has, the greater the chance is that the miner or pool has to mine a block. As miners add more hash rate, more sec Continue reading >>
What Is Bitcoin Halving Event And When Does It Happen?
Before we go deeper into the effects of bitcoin halving, lets take a look at some basic concepts pertaining to bitcoin mining . Upon the creation of a new transaction, the information is sent to all the other nodes present on bitcoins network along with the ones making contributions to the overall mining process . The information of these transactions are stored locally, and miners get rewarded for publishing this block of a transaction on the blockchain . In order to do this, miners have to contribute their computing power so as to solve a challenge requiring high processing power. The reward that a miner gets for successfully publishing a transaction depends on the block reward. Currently, the block reward is set at 12.5 BTC. While many people do know about mining or can easily learn about it from various sources, they do wonder what the hell halving is whenever they come across the term bitcoin halving. The main purpose of this guide is to provide an answer to this question! Since the time that Bitcoin has been on the market, it has been following a code that was written many years back- almost a decade ago. One of the reasons why bitcoins are highly valuable is the limited supply of bitcoins which is 21 Million. Hence, it works in a similar way as resources such as gold do. Before heading on to the formal definition of halving, let us consider the two factors that affect the rewards. To make things somewhat competitive, the code of bitcoin was written in a way so as to make miners compete with each other for the reward. Hence, the greater the number of miners there are on a network, the more difficult it is for a single miner to win. With an increase in the competition, miners tend to make use of greater processing power hence ruling out the likelihood of anyone ma Continue reading >>
The Reward For Mining Bitcoin Was Just Cut In Half
The reward for mining Bitcoin was just cut in half Hype check: Pokmon Go says more about Pokmon than it does about AR Bitcoin just experienced a major milestone in its short little lifespan. The reward for mining a block (a block = a ledger of transaction data) was just cut in half from 25 bitcoinsto 12.5 bitcoins. This means that assuming a price of $650 per coin,going forward miners will make ~$8,125 per block they mine, compared to $16,250 before the halving. But its ok! This is allsupposed to happen. Let me explain. When the code for Bitcoin was written, it was designed to be a currency with no more than 21 million bitcoins ever in circulation. And to encourage people to mine (which is what validates and supports the entire bitcoin network), Satoshi created a reward that went along with each block. When Bitcoin was first created, the reward was set at 50 bitcoins per block mined. And, the code specified that every 210,000 blocks mined that reward would be cut in half, until it eventually is reduced to zero after 64 halving events. This exponential halving means that even though the last halving wont occur for over 100 years, 75% of all bitcoins have already been mined and distributed. So, today was the second ever halving in the history of Bitcoin. The first halving (when the reward was cut from 50 to 25 bitcoins) was back in November of 2012, when the price was around $12 dollars. Ok, enough of the history lesson. You probably just want to know how this will effect the price of bitcoin. In a perfect market the USD/BTC price would have simply doubled, to compensate for half as much bitcoinbeing rewarded. This logically would make sense, since the cost of mining isnt changing at all, and without a doubling of price miners are instantly seeing their revenue cut in ha Continue reading >>
Quote from: legarde23 on May 27, 2017, 05:55:26 AM Is it better to buy bitcoin when bitcoin halving come? I think it is better to buy bitcoin before the halving come. Bitcoin history shows that there is always an increase in price when bitcoin halving occurred. So it would be best to buy bitcoin when bitcoin halving is a year away since hype start as early as six months from the halving events. From that you can at least get a profit from the increase due to bitcoin halving hype. The last halving happened at June 2016 and the price went from 400 to 600-700 dollars before the halving, then dropped a bit and started to raise, the halving were a measure to make bitcoin get more value over time, knowing the halving does reduce the reward to half, it makes the price to double every 210 000 bitcoin blocks, the next one will happen at 2020, if you take into consideration the last halving the new price would be around 1200-1400 dollars, but we are already at those soo, the sky is the limit.

What To Expect When The Bitcoin Halving Happens - Coindesk
What to Expect When the Bitcoin Halving Happens It's an event that brings equal parts predictability and uncertainty. For close to a year, bitcoin miners and investors have been preparing for anetwork changenicknamed ' the halving '.At approximately 18:00 UTC tomorrow, the subsidy the bitcoin network uses to compensate miners will dropfrom 25 BTCto 12.5 BTC, never to increase again. Yet, despite its scheduled arrival, many in the industry remain unsure just how significant an impact it could have on bitcoin's still-volatile price and the health of the distributed payment network's transaction validators (akaminers). A programmed feature in the code, the bitcoin subsidycontrols the supply of new bitcoins that are released into the market with each new block. When bitcoin first launched, a miner could earn 50 BTC for sealing a block on the blockchain ledger.After 210,000 blocks, or approximately four years, however, the reward was cut in half to 25. And tomorrow, as block 420,000 is sealed, miners will be left with a reward of 12.5 bitcoin. As currently set, only 21m BTC will ever be mined, a figure that would require the consensus of all or most bitcoin users to change. Because the figure does not vary or become irregular, there is a steady, predictable supply of new bitcoins.To traders, this has quelled some uncertainty regarding how many new bitcoins could suddenly appear for sale, and to miners, it has provided a steady incentive for them to continue maintaining bitcoin's ledger. Complicating matters, however, is that not all traders are altruistic and that mining costs money, and since bitcoin's price impacts other areas of the ecosystem, some believe this delicate balance could be altered by the halving.

What Happens To Bitcoin Price Amid Halving?
What Happens to Bitcoin Price amid Halving? Join our community of 10 000 traders on Hacked.com for just $39 per month. The bitcoin price has increased nearly 50% since January 1.While the year has been tumultuous economically for the world, an upcoming network event called a Bitcoin halving could have had price implications and led to the big gains forBitcoin price. Though, based on the only historical halving, which took place in 2012, the unsurprising nature of the halving event could limit price volatility. At least for now. Using computers to contribute transaction data to the bitcoin blockchain, miners must provide a proof of work to receive a Bitcoin block reward for cracking codes and mining Bitcoin. When Satoshi Nakamoto implemented the protocol, the block reward was 50 BTC. Its set to drop to 12.5 BTC tomorrow. The reward will have until the 21 millionth bitcoin is mined. Those most heavily invested in Bitcoin have been aware of the forthcoming event, which could tame the effect the halving has on prices. On social media and in forums, bitcoiners celebrate the possibility of a price increase. In reality, anything is possible. The halving does portend a certain degree of uncertainty; however, the 2012 example demonstrates a steep price increase in the months following. Assuming the vector of Bitcoin is progressing faster, then it might be mere weeks before price repercussions are felt. The price of Bitcoin before the first block reward halving from 50 BTC to 25 BTC in 2012 was $12.65. A year later it reached nearly $1,300. If the same price action is to be expected, that places Bitcoin at $65,000 per coin in August of next year. The next halving is predicted to take place sometime around late 2019 or early 2020. Headlines throughout the internet will push their Continue reading >>
What Is Bitcoin Halving? Complete Guide To This Mining Change
What is Bitcoin Halving? Complete Guide to this Mining Change Robert Devoe on March 20, 2018 / 0 Comments Every four years or so, bitcoin undergoes an important event known as the bitcoin halving. This first happened in 2012, and again in 2016. Likewise, it will happen again sometime in 2020 and 2024. What is the bitcoin halving? What impacts does it have on the economics of bitcoin? In this article, were going to go over what the bitcoin halving is, and why its so important to bitcoin. Each day, many untold thousand watts of electricity are committed towards bitcoin mining. People mine bitcoin because they hope to earn bitcoin, which has value and can be bought and sold in various markets. Without going into too much detail, mining is the process by which the network is secured and transactions are processed. In order to encourage people to mine bitcoin (or other cryptocurrencies that also use proof of work mining), each block contains a reward. That reward is released to the miner that successfully solves the block. This reward needs to be high enough so as to be a strong incentive. But the reward also cannot be too much. A large reward would cause an oversupply and lower the value of the currency. When Satoshi Nakamoto created bitcoin, he wanted to create a system that would be self-sustaining and that would in some ways emulate gold-mining. That being, over time, mining would become more difficult and the rewards collected would slowly reduce so as to control the supply. Specifically, Nakamoto writes: The steady addition of a constant of amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended. Nakamotos solution to this problem is to institute a bitcoin halving syst Continue reading >>
What Is The Bitcoin Halving And Why Is It Important?
What is the Bitcoin Halving and Why is It Important? July 08, 2016, 04:37:59 PM EDT By Bitcoin Magazine An event is about to take place on the Bitcoin network that only happens roughly every four years. The amount of new bitcoin created and earned by miners with each new block of transactions is about to be cut in half. This is part of bitcoins predictable, transparent monetary policy , which can be verified in the source code available on the Bitcoin Core GitHub repository . When these sorts of changes in bitcoins inflation rate take place, it's known as a halving event . This upcoming halving is expected to take place this Saturday when block 420,000 is mined. Before getting into the effects of the bitcoin halving, its important to understand some of the basics of bitcoin mining . When someone creates a new Bitcoin transaction, it is sent around to all of the other nodes on the network, including those who are also contributing to the mining process. These transactions are collected and stored locally while the miners are also working on a puzzle of sorts, which requires a lot of computing power to solve. If a miner solves the puzzle before anyone else, they earn the ability to publish the new block of transactions to the public blockchain and collect a reward of 25 bitcoins (soon to be 12.5 bitcoins) plus any transaction fees. The mining process is the genius of Satoshi Nakamoto s creation. Miners essentially prove that they have skin in the game by trying to solve the puzzle that goes along with each new block of transactions. The ability to solve that puzzle proves to the rest of the network that the miner spent money on various resources (hardware, electricity, etc.) and has earned the right to mine a block. The miner is willing to spend money on those resources Continue reading >>
Bitcoin Price Drops 5% Amid 'halving'
Photograph by Tomohiro Ohsumi Bloomberg/Getty Images A version of this post titled Bitcoin halves and have-nots originally appeared in the Cyber Saturday edition of Data Sheet , Fortunes daily tech newsletter. Bitcoin, the digital money, has just undergone its second-ever halving event. Hard-coded into cryptocurrencys rulebook is a law that cuts in half the value of the digital payout that so-called miners receive for supporting the network with their computing power. The event happens about every four years. (More specifically, after every 210,000 blocks of transactions are processed.) As Balaji Srinivasan, CEO of the Andreessen Horowitz-backed Bitcoin company 21, described it, the occasion is a sort of New Years Eve for financial futurists. The halving event has provenand will continue to prove consequential for the mining set . The Bitcoin backers who supply the CPU time and electricity that fuel the Bitcoin network do so to recoup a reward. Although the markets have been pricing in the impact of the long-awaited trim over the past few weeks, some miners face an uncertain fate: their prize just dropped to 12.5 Bitcoins per processed block, down from 25. With less potential revenue on the table, fewer miners may survive. Already, KnCMiner, a Swedish Bitcoin mining startup, filed for bankruptcy in May . As the halving got underway, Bitcoins price fell 5% to near $627 per Bitcoin from about $660, according to CoinDesk data . At press time, the value of the cryptocurrency appeared to be recovering from the initial drop; its price hovered at just under $640, about a 4% drop for the day. Expect more volatility as the markets adjust. Since the beginning of the year, Bitcoins value has risen almost 50%a couple hundred-dollar increase, likely in anticipation of the impending Continue reading >>
