Numerous people have been suggested as possible Satoshi Nakamotos by major media outlets. On Oct. 10, 2011, The New Yorker published an article speculating that Nakamoto might be Irish cryptography student Michael Clear, or economic sociologist Vili Lehdonvirta. A day later, Fast Company suggested that Nakamoto could be a group of three people – Neal King, Vladimir Oksman and Charles Bry – who together appear on a patent related to secure communications that was filed two months before bitcoin.org was registered. A Vice article published in May 2013 added more suspects to the list, including Gavin Andresen, the Bitcoin project’s lead developer; Jed McCaleb, co-founder of now-defunct Bitcoin exchange Mt. Gox; and famed Japanese mathematician Shinichi Mochizuki. 
If you have the required hardware, you can mine bitcoin even if you are not a miner. There are different ways one can mine bitcoin such as cloud mining, mining pool, etc. For cloud mining, all you need to do is to connect to the datacenter and start mining. The good thing about this is that you can mine from anywhere and you don’t need a physical hardware to mine.

Mining is the process of spending computation power to secure Bitcoin transactions against reversal and introducing new Bitcoins to the system. Technically speaking, mining is the calculation of a hash of the block header, which includes among other things a reference to the previous block, a hash of a set of transactions and a nonce (an arbitrary number used just once for authentication purposes).
Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility. Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility.[117]
Before even starting out with Bitcoin mining, you need to do your due diligence. The best way to do this, as we’ve discussed, is through the use of a Bitcoin mining calculator. Bear in mind that mining costs money! If you don’t have a few thousand dollars to spare on the right miner, and if you don’t have access to cheap electricity, mining Bitcoin might not be for you.
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.”

For years, few residents really grasped how appealing their region was to miners, who mainly did their esoteric calculations quietly tucked away in warehouses and basements. But those days are gone. Over the past two years, and especially during 2017, when the price of a single bitcoin jumped from $1,000 to more than $19,000, the region has taken on the vibe of a boomtown. Across the three rural counties of the Mid-Columbia Basin—Chelan, Douglas and Grant—orchards and farm fields now share the rolling landscape with mines of every size, from industrial-scale facilities to repurposed warehouses to cargo containers and even backyard sheds. Outsiders are so eager to turn the basin’s power into cryptocurrency that this winter, several would-be miners from Asia flew their private jet into the local airport, took a rental car to one of the local dams, and, according to a utility official, politely informed staff at the dam visitors center, “We want to see the dam master because we want to buy some electricity.”


One of Bitcoin’s most appealing features is its ruthless verification process, which greatly minimizes the risk of fraud. Since Bitcoin is decentralized, volunteers—referred to as “miners”—constantly verify and update the blockchain. Once a specific amount of transactions are verified, another block is added to the blockchain and business continues per usual.
Across the Mid-Columbia Basin, miners faced an excruciating dilemma: cut their losses and walk, or keep mining for basically nothing in the hopes that the cryptocurrency market would somehow turn around. Many smaller operators simply folded and left town—often leaving behind trashed sites and angry landlords. Even larger players began to draw lines in the sand. Carlson started moving out of mining and into hosting and running sites for other miners. Others held on. Among the latter was Salcido, the Wenatchee contractor-turned-bitcoin miner who grew up in the valley. “What I had to decide was, do I think this recovers, or does the chart keep going like this and become nothing?” Salcido told me recently. We were in his office in downtown Wenatchee, and Salcido, a clean-cut 43-year-old who is married with four young kids, was showing me a computer chart of the bitcoin price during what was one of the most agonizing periods of his life. “Month over month, you had to make this decision: Am I going to keep doing this, or am I going to call it?” 

How hard are the puzzles involved in mining? Well, that depends on how much effort is being put into mining across the network. The difficulty of the mining can be adjusted, and is adjusted by the protocol every 2016 blocks, or roughly every 2 weeks. The difficulty adjusts itself with the aim of keeping the rate of block discovery constant. Thus if more computational power is employed in mining, then the difficulty will adjust upwards to make mining harder.  And if computational power is taken off of the network, the opposite happens. The difficulty adjusts downward to make mining easier.
The whole process is pretty simple and organized: Bitcoin holders are able to transfer bitcoins via a peer-to-peer network. These transfers are tracked on the “blockchain,” commonly referred to as a giant ledger. This ledger records every bitcoin transaction ever made. Each “block” in the blockchain is built up of a data structure based on encrypted Merkle Trees. This is particularly useful for detecting fraud or corrupted files. If a single file in a chain is corrupt or fraudulent, the blockchain prevents it from damaging the rest of the ledger.
The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes.
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.
Armory is the most mature, secure and full featured Bitcoin wallet but it can be technologically intimidating for users. Whether you are an individual storing $1,000 or institution storing $1,000,000,000 this is the most secure option available. Users are in complete control all Bitcoin private keys and can setup a secure offline-signing process in Armory.
In the process of mining, each Bitcoin miner is competing with all the other miners on the network to be the first one to correctly assemble the outstanding transactions into a block by solving those specialized math puzzles. In exchange for validating the transactions and solving these problems. Miners also hold the strength and security of the Bitcoin network. This is very important for security because in order to attack the network, an attacker would need to have over half of the total computational power of the network. This attack is referred to as the 51% attack. The more decentralized the miners mining Bitcoin, the more difficult and expensive it becomes to perform this attack.
Venture capitalists, such as Peter Thiel's Founders Fund, which invested US$3 million in BitPay, do not purchase bitcoins themselves, but instead fund bitcoin infrastructure that provides payment systems to merchants, exchanges, wallet services, etc.[150] In 2012, an incubator for bitcoin-focused start-ups was founded by Adam Draper, with financing help from his father, venture capitalist Tim Draper, one of the largest bitcoin holders after winning an auction of 30,000 bitcoins,[151] at the time called "mystery buyer".[152] The company's goal is to fund 100 bitcoin businesses within 2–3 years with $10,000 to $20,000 for a 6% stake.[151] Investors also invest in bitcoin mining.[153] According to a 2015 study by Paolo Tasca, bitcoin startups raised almost $1 billion in three years (Q1 2012 – Q1 2015).[154]
To add a new block to the chain, a miner has to finish what’s called a cryptographic proof-of-work problem. Such problems are impossible to solve without applying a ton of brute computing force, so if you have a solution in hand, it’s proof that you’ve done a certain quantity of computational work. The computational problem is different for every block in the chain, and it involves a particular kind of algorithm called a hash function.
In Charles Stross' 2013 science fiction novel, Neptune's Brood, the universal interstellar payment system is known as "bitcoin" and operates using cryptography.[235] Stross later blogged that the reference was intentional, saying "I wrote Neptune's Brood in 2011. Bitcoin was obscure back then, and I figured had just enough name recognition to be a useful term for an interstellar currency: it'd clue people in that it was a networked digital currency."[236]

For local cryptocurrency enthusiasts, these slings and arrows are all very much worth enduring. They believe not only that cryptocurrency will make them personally very wealthy, but also that this formerly out-of-the-way region has a real shot at becoming a center—and maybe the center—of a coming technology revolution, with the well-paid jobs and tech-fueled prosperity that usually flow only to gilded “knowledge” hubs like Seattle and San Francisco. Malachi Salcido, a Wenatchee building contractor who jumped into bitcoin in 2014 and is now one of the basin’s biggest players, puts it in sweeping terms. The basin, he tells me, is “building a platform that the entire world is going to use.”
Instead, the ledger is broken up into blocks: discrete transaction logs that contain 10 minutes worth of bitcoin activity apiece. Every block includes a reference to the block that came before it, and you can follow the links backward from the most recent block to the very first block, when bitcoin creator Satoshi Nakamoto conjured the first bitcoins into existence.
Though Bitcoin was not designed as a normal equity investment (no shares have been issued), some speculative investors were drawn to the digital money after it appreciated rapidly in May 2011 and again in November 2013. Thus, many people purchase bitcoin for its investment value rather than as a medium of exchange. But their lack of guaranteed value and digital nature means the purchase and use of bitcoins carries several inherent risks. Many investor alerts have been issued by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), the Consumer Financial Protection Bureau (CFPB), and other agencies.
Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto[9] and released as open-source software in 2009.[10] Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[11] products, and services. Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[12]
