Bitmain gained an edge by supplying a superior product in large quantities, a feat that has eluded every other company in the industry. The Ordos facility is stuffed almost exclusively with Bitmain’s best performing rig, the Antminer S9. According to company specs, the S9 is capable of churning out 14 terahashes, or 14 trillion hashes, every second while consuming around 0.1 joules of energy per gigahash for a total of about 1,400 watts (about as much as a microwave oven consumes).
This gives the pool members a more frequent, steady payout (this is called reducing your variance), but your payout(s) can be decreased by whatever fee the pool might charge. Solo mining will give you large, infrequent payouts and pooled mining will give you small, frequent payouts, but both add up to the same amount if you're using a zero fee pool in the long-term.
Electricity cost: How many dollars are you paying per kilowatt? You’ll need to find out your electricity rate in order to calculate profitability. This can usually be found on your monthly electricity bill. The reason this is important is that miners consume electricity, whether for powering up the miner or for cooling it down (these machines can get really hot).
Paint mixing is a good way to think about the one-way nature of hash functions, but it doesn’t capture their unpredictability. If you substitute light pink paint for regular pink paint in the example above, the result is still going to be pretty much the same purple, just a little lighter. But with hashes, a slight variation in the input results in a completely different output:
As specified by the Bitcoin protocol, each miner is rewarded by each block mined.  Currently, that reward is 12.5 new Bitcoins for each block mined. The Bitcoin block mining reward halves every 210,000 blocks, when the coin reward will decrease from 12.5 to 6.25 coins.  Currently, the total number of Bitcoins left to be mined amounts to 4,293,388. This means that 16,706,613 Bitcoins are in circulation, and that the total number of blocks available until mining reward is halved is 133,471 blocks till 11:58:04 12th Jun, 2020 When the mining reward will be halved.
Electrum gets high marks for its ease of use and user interface, which is always nice, but the real reason it's the best bitcoin wallet for desktop is its safety and reliability. Like any desktop wallet that's worth its salt, users get to control their private key; Electrum doesn't know what it is. Since your private key, a long string of letters and numbers, gives you access to your bitcoin, you need to keep that, you know, private.
These days, Miehe says, a serious miner wouldn’t even look at a site like that. As bitcoin’s soaring price has drawn in thousands of new players worldwide, the strange math at the heart of this cryptocurrency has grown steadily more complicated. Generating a single bitcoin takes a lot more servers than it used to—and a lot more power. Today, a half-megawatt mine, Miehe says, “is nothing.” The commercial miners now pouring into the valley are building sites with tens of thousands of servers and electrical loads of as much as 30 megawatts, or enough to power a neighborhood of 13,000 homes. And in the arms race that cryptocurrency mining has become, even these operations will soon be considered small-scale. Miehe knows of substantially larger mining projects in the basin backed by out-of-state investors from Wall Street, Europe and Asia whose prospecting strategy, as he puts it, amounts to “running around with a checkbook just trying to get in there and establish scale.”

The attraction then, as now, was the Columbia River, which we can glimpse a few blocks to our left. Bitcoin mining—the complex process in which computers solve a complicated math puzzle to win a stack of virtual currency—uses an inordinate amount of electricity, and thanks to five hydroelectric dams that straddle this stretch of the river, about three hours east of Seattle, miners could buy that power more cheaply here than anywhere else in the nation. Long before locals had even heard the words “cryptocurrency” or “blockchain,” Miehe and his peers realized that this semi-arid agricultural region known as the Mid-Columbia Basin was the best place to mine bitcoin in America—and maybe the world.
Miehe still runs his original mine, a half-megawatt operation not far from the carwash. But his main job these days is managing hosting sites for other miners and connecting outsiders with insiders—and he’s OK with that. He sold off some of his bitcoin stack, just after Christmas. He’s still bullish on crypto, and on the basin’s long-term prospects. But he no longer has any appetite for the race for scale. Gone are the glory days when commercial miners could self-finance with their own stacks. Today, you need outside financing—debt—which, for Miehe, who now has two young children, would mean an unacceptable level of stress. “I’ve already done it,” he says. “My entire data center was built with bitcoin, from nothing. I’ve already won enough for what I was looking for out of mining.” He pauses. “The risk and reward is getting pretty great,” he says. “And I’m not sure I want to be on the front line of that battle.”
Ledger’s main competitor in the market space is the original Trezor hardware wallet. One of the key advantages of the Ledger over the Trezor is the freedom to create your own unique passphrases. Both the Ledger and the Trezor require 20 passphrases for recovery and reset purposes; however, the Trezor package sends the user a random list. The Ledger gives the user the freedom to create their own. Additionally, if aesthetics matter to you, the Ledger sports an arguably sleeker design than the Trezor.
In the zero-sum game that cryptocurrency has become, one man’s free money is another man’s headache. In the Mid-Columbia Basin, the latter category includes John Stoll, who oversees Chelan County Public Utility District’s maintenance crews. Stoll regards people like Benny as “rogue operators,” the utility’s term for small players who mine without getting proper permits and equipment upgrades, and whose numbers have soared in the past 12 months. Though only a fraction of the size of their commercial peers, these operators can still overwhelm residential electric grids. In extreme cases, insulation can melt off wires. Transformers will overheat. In one instance last year, the utility says, a miner overloaded a transformer and caused a brush fire.
Let your computer earn you money with Bitcoin Miner, the free easy-to-use Bitcoin miner! Earn Bitcoin which can be exchanged for real-world currency! Works great at home, work, or on the go. Download Bitcoin Miner and start mining Bitcoin today! Bitcoin miners perform complex calculations known as hashes. Each hash has a chance of yielding bitcoins. The more hashes performed, the more chances of earning bitcoins. Most people join a mining pool to increase their chances of earning bitcoins. Mining pools pay for high value hashes known as shares. The default mining pool issues payouts weekly to accounts with at least 5000 Satoshis. If an account doesn't reach 5000 Satoshis during a week, the balance carries forward (it is never lost).
The initialization process is relatively simple. Plug it into a USB port on your device. You will then have to generate a private key by adding 256 KB to the drive. You can do this by dragging one or two random pictures into it. After the private key is generated the drive will self-eject. It is now ready to use. To manage your assets and view your digital address you will have to open the index.htm file located on the drive. The user interface is very easy to use and even provides links to several blockchain browsers.
With bitcoin, on the other hand, the supply is tightly controlled by the underlying algorithm. A small number of new bitcoins trickle out every hour, and will continue to do so at a diminishing rate until a maximum of 21 million has been reached. This makes bitcoin more attractive as an asset – in theory, if demand grows and the supply remains the same, the value will increase.
But here, Carlson and his fellow would-be crypto tycoons confronted the bizarre, engineered obstinacy of bitcoin, which is designed to make life harder for miners as time goes by. For one, the currency’s mysterious creator (or creators), known as “Satoshi Nakamoto,” programmed the network to periodically—every 210,000 blocks, or once every four years or so—halve the number of bitcoins rewarded for each mined block. The first drop, from 50 coins to 25, came on November 28, 2012, which the faithful call “Halving Day.” (It has since halved again, to 12.5, and is expected to drop to 6.25 in June 2020.)
A CMU researcher estimated that in 2012, 4.5% to 9% of all transactions on all exchanges in the world were for drug trades on a single dark web drugs market, Silk Road.[30] Child pornography,[31] murder-for-hire services,[32] and weapons[33] are also allegedly available on black market sites that sell in bitcoin. Due to the anonymous nature and the lack of central control on these markets, it is hard to know whether the services are real or just trying to take the bitcoins.[34]
You’ll need a Bitcoin wallet in which to keep your mined Bitcoins. Once you have a wallet, make sure to get your wallet address. It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address, but most wallets are pretty straightforward about it. Notice that you’ll need your PUBLIC Bitcoin address and not your private key (which is like the secret password for your wallet).
Bitcoin mining operations take a lot of effort and power, and the sheer amount of competition makes it difficult for newcomers to enter the race and profit. A new miner would not only need to have adequate computing power and the knowledge to use it to outcompete the competition, but would also need the extensive amount of capital necessary to fund the operations.

Various potential attacks on the bitcoin network and its use as a payment system, real or theoretical, have been considered. The bitcoin protocol includes several features that protect it against some of those attacks, such as unauthorized spending, double spending, forging bitcoins, and tampering with the blockchain. Other attacks, such as theft of private keys, require due care by users.[13][14][15][16][17][18][19]
But due to the volatility of bitcoin, it’s impossible to predict the annual revenue of a mining farm. On my flight from China back to the United States, the price of bitcoin crashed 25 percent, from $2,400 to $1,800. In no time at all the operation I visited was bringing in $50,000 less per day. Within a week it was back up, and approaching an all-time high.
There are no physical bitcoins, only balances kept on a public ledger in the cloud, that – along with all Bitcoin transactions – is verified by a massive amount of computing power. Bitcoins are not issued or backed by any banks or governments, nor are individual bitcoins valuable as a commodity. Despite its not being legal tender, Bitcoin charts high on popularity, and has triggered the launch of other virtual currencies collectively referred to as Altcoins.
Bitcoin mining is the process by which the transaction information distributed within the Bitcoin network is validated and stored on the blockchain. Bitcoin mining serves to both add transactions to the block chain and to release new Bitcoin. The concept of Bitcoin mining is simply the process of generating additional Bitcoins until the supply cap of 21 million coins has been reached.  What makes the validation process for Bitcoin different from traditional electronic payment networks is the absence of middle man in the architecture. The process of validating transactions and committing them to the blockchain involves solving a series of specialized math puzzles. In the process of adding transactions to the network and securing them into the blockchain, each set of transactions that are processed is called block, and multiple chains of blocks is referred to as the blockchain.
What separated these survivors from the quitters and the double-downers, Carlson concluded, was simply the price of electricity. Survivors either lived in or had moved to places like China or Iceland or Venezuela, where electricity was cheap enough for bitcoin to be profitable. Carlson knew that if he could find a place where the power wasn’t just cheap, but really cheap, he’d be able to mine bitcoin both profitably and on an industrial scale.
Granted, all that real-worlding and road-hitting is a little hard to visualize just now. The winter storms that have turned the Cascade Mountains a dazzling white have also turned the construction site into a reddish quagmire that drags at workers and equipment. There have also been permitting snafus, delayed utility hookups, and a lawsuit, recently settled, by impatient investors. But Carlson seems unperturbed. “They are actually making it work,” he told me earlier, referring to the mud-caked workers. “In a normal project, they might just say, ‘Let’s just wait till spring,’” Carlson adds. “But in bitcoin and blockchain, there is no stopping.” Indeed, demand for hosting services in the basin is so high that a desperate miner offered Carlson a Lamborghini if Carlson would bump him to the head of the pod waiting list. “I didn’t take the offer,” Carlson assures me. “And I like Lamborghinis!”

The first post was made on 31 August and suggested that the funds may be connected to the now-defunct dark web market Silk Road which handled the trade of billions of dollars worth of contraband such as recreational and prescription drugs, illegal weapons and pornography, malware, hacking services, guides to various types of criminal activity, and other black market goods and services.
I think many institutions are buying quietly before the next rally and before the next halving: http://www.bitcoinblockhalf.com/ This is a great time to accumulate. The upside potential overweighs many times any downside risk. And with the stock market peaking, more money will start flowing into Bitcoin. submitted by /u/simplelifestyle [link] [comments]

Bitcoin's origin story sounds like something out of science fiction: It was launched in 2008 on the heels of a white paper published by the mysterious Satoshi Nakamoto, whose real identity – and country of origin – are unknown. Nakamoto conceived of Bitcoin as a currency that was 1) encrypted; 2) decentralized, i.e. it was ungoverned and did not belong to any nation; and 3) a digital "distributed ledger," such that everyone can verify online the legitimacy of transactions.


The incremental complexity and technological know-how needed for this method are both downsides to the paper wallet approach. Cold storage solutions and hardware wallets are less nimble than other options, too; if the price of bitcoin were crashing, for example, you might find yourself slower to the draw than if you merely kept your BTC on a site like Coinbase.
Eventually, you will want to access the Bitcoins or Litecoins stored on it. If you have the first version of OpenDime, you will need to break off a plastic "tongue" in the middle of the flash stick. Later versions work much like resetting old routers. You will need to push a pin through a marked section of the drive. Both of these processes physically change the drive. After doing this the private key associated with that OpenDime will be downloaded onto your pc or mobile device. This is the most vulnerable point in using the OpenDime. Make sure that you are using a secured system when doing this. You can then use the private key to access your funds in the same way you would with any other platform.
Because the reward for mining blocks is so high (currently at 12.5 BTC), the competition to win that reward is also fierce among miners. At any moment, hundreds of thousands of supercomputers all around the world are competing to mine the next block and win that reward. In fact, according to howmuch.com, ” the total power of all the computers mining Bitcoin is over 1000 times more powerful than the world’s top 500 supercomputers combined”.
Legal Gray Area. Major governments have largely remained on the sidelines, and this has created both a sense of potential and apprehension for Bitcoin proponents and critics respectively. Bitcoin isn’t backed by a regulatory agency and a government would technically be ceding power by supporting a decentralized currency. This has been largely officially unaddressed. Bitcoin’s price, however, tends to be very sensitive to any news concerning the US government’s opinion of cryptocurrencies. For example, when the SEC denied the approval of bitcoin-based exchange-traded-products—essentially bitcoin-backed assets on the stock market—in 2017, Bitcoin’s price dropped 18%. Yet while the price and adoption of Bitcoin would be affected by government action, governments are unable to criminalize Bitcoin. In fact, governments such as the United States and China have invested in it at some capacity.
Cryptocurrency mining can be an expensive proposition, requiring computing hardware and electricity. Cryptojacking offers cybercriminals a way to steal computing power from other people to bypass the effort and expense. Cryptojacking software operates on computers in the background, with the only evidence of its presence signified by a user’s device overheating or slowing down.

More broadly, the region is watching uneasily as one of its biggest natural resources—a gigantic surplus of hydroelectric power—is inhaled by a sector that barely existed five years ago and which is routinely derided as the next dot-com bust, or this century’s version of the Dutch tulip craze, or, as New York Times columnist Paul Krugman put it in January, a Ponzi scheme. Indeed, even as Miehe was demonstrating his prospecting chops, bitcoin’s price was already in a swoon that would touch $5,900 and rekindle widespread doubts about the future of virtual currencies.

Nigel Dodd argues in The Social Life of Bitcoin that the essence of the bitcoin ideology is to remove money from social, as well as governmental, control.[124] Dodd quotes a YouTube video, with Roger Ver, Jeff Berwick, Charlie Shrem, Andreas Antonopoulos, Gavin Wood, Trace Meyer and other proponents of bitcoin reading The Declaration of Bitcoin's Independence. The declaration includes a message of crypto-anarchism with the words: "Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian."[124][123]
