I’m a newbie and everything I’ve read on here is extremely easy to comprehend! Thank you so much for all the valuable information. For those of us who don’t code or do any computing, it’s really great to be able to read something (like these articles) and not need an encyclopedia to make any sense! It gives us a chance to participate and get involved (at a slower rate albeit), and possibly earn a little something as well. Thank you!
Unfortunately, “participating” in Bitcoin mining isn’t the same thing as actually making money from it. The new ASIC chips on the market today are specifically designed for mining Bitcoin. They’re really good at Bitcoin mining, and every time someone adds a new ASIC-powered computer to the Bitcoin network, it makes Bitcoin mining that much more difficult.
But Bolz, a longtime critic of cryptocurrency, says local concerns go beyond economics: Many residents he hears from aren’t keen to see so much public power sold to an industry whose chief product is, in their minds, of value only to speculators and criminals. “I mean, this is a conservative community, and they’re like, ‘What the hell’s wrong with dollars?’” says Bolz. “If you just went out and did a poll of Chelan County, and asked people, ‘Do you want us to be involved in the bitcoin industry, they would say not only ‘No,’ but ‘Hell no.’”
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”.
Speculation drives numbers. Many Bitcoin users are holding onto their bitcoins in hopes of selling them off for an enormous profit one day. With news articles portraying Bitcoin millionaires as lucky kids who got in early, you can’t really blame them. For example, if you had spent your $5 latte money on 2,000 bitcoins one morning in 2010, they would be worth about $5.4 million today. Makes you really wish you’d managed your Starbucks budget better, doesn’t it?
Client-side encryption means all of your data is encrypted on your device before any of your information touches our servers. No server-side hacks, no malware = safe assets. That also means that  Edge as a company does not have access to, nor have any knowledge of your account information. Only you and you alone has access and control of your assets—the way it should be.
These dynamics have resulted in a race among miners to amass the fastest, most energy-efficient chips. And the demand for faster equipment has spawned a new industry devoted entirely to the computational needs of Bitcoin miners. Until late 2013, generic graphics cards and field-programmable gate arrays (FPGAs) were powerful enough to put you in the race. But that same year companies began to sell computer chips, called application-specific integrated circuits (ASICs), which are specifically designed for the task of computing the Bitcoin hashing algorithm. Today, ASICs are the standard technology found in every large-scale facility, including the mining farm in Ordos. When Bitmain first started making ASICs in 2013, the field was thick with competitors—BitFury, a multinational ASIC maker; KnCMiner in Stockholm; Butterfly Labs in the United States; Canaan Creative in Beijing; and about 20 other companies spread around China.

Ultimately, Bitcoin mining is becoming an arms race. In the early days, anyone with a decent PC could generate Bitcoins through Bitcoin mining. Today, you need to collaborate with other Bitcoin miners in pools, strategically choose the location of your Bitcoin mining operation, and purchase ASIC-powered computers that are specially designed to handle Bitcoin mining.

“Cryptojacking scams have continued to evolve, and they don’t even need you to install anything,” Jason Adler, an assistant director for the Federal Trade Commission, wrote in a blog post in June. “Scammers can use malicious code embedded in a website or an ad to infect your device. Then they can help themselves to your device’s processor without you even knowing.”
A specific problem that an internet payment system must solve is double-spending, whereby a user pays the same coin to two or more different recipients. An example of such a problem would be if Eve sent a bitcoin to Alice and later sent the same bitcoin to Bob. The bitcoin network guards against double-spending by recording all bitcoin transfers in a ledger (the blockchain) that is visible to all users, and ensuring for all transferred bitcoins that they haven't been previously spent.[14]:4

It is conceivable that an ASIC device purchased today would still be mining in two years if the device is power efficient enough and the cost of electricity does not exceed it's output. Mining profitability is also dictated by the exchange rate, but under all circumstances the more power efficient the mining device, the more profitable it is. If you want to try your luck at bitcoin mining then this Bitcoin miner is probably the best deal.
Even in the recent price crash, the miners have maintained their upbeat attitude, in part because they’ve died this death a few times before. In February, a day after bitcoin’s price dipped below $6,000, I checked in with Carlson to see how he was dealing with the huge sell-off. In a series of long texts, he expressed only optimism. The market correction, he argued, had been inevitable, given the rapid price increase. He noted that mining costs in the basin remain so low—still just a little above $2,000 per coin—that prices have a way to fall before bitcoin stops being worth mining there. Carlson is, he told me, “100 percent confident” the price will surpass the $20,000 level we saw before Christmas. “The question, as always, is how long will it take.”
Satoshi Nakamoto is credited with designing Bitcoin. Nakamoto claims to be a man living in Japan born on April 5th, 1975 but there are speculations that he is actually either an individual programmer or group of programmers with a penchant for computer science and cryptography scattered around the United States or Europe. Nakamoto is believed to have created the first blockchain database and have been the first to solve the double spending problem other digital currency failed to. While Bitcoin’s creator is shrouded in mystery, his Wizard of Oz status hasn’t stopped the digital currency from becoming increasingly popular with individuals, businesses, and even governments.

Another interesting way (literally) to earn bitcoins is by lending them out, and being repaid in the currency. Lending can take three forms – direct lending to someone you know; through a website which facilitates peer-to-peer transactions, pairing borrowers and lenders; or depositing bitcoins in a virtual bank that offers a certain interest rate for Bitcoin accounts. Some such sites are Bitbond, BitLendingClub and BTCjam. Obviously, you should do due diligence on any third-party site.


No. 3: Electrum (software wallet). Electrum is a popular, free storage option in the bitcoin community, and is one of the most, if not the most, well-respected desktop storage apps out there. It's been around since 2011 and is also available for mobile, though Apple (ticker: AAPL) iPhone users are out of luck – to date it's only supported by Android.

Bitcoin Mining is a peer-to-peer computer process used to secure and verify bitcoin transactions—payments from one user to another on a decentralized network. Mining involves adding bitcoin transaction data to Bitcoin's global public ledger of past transactions. Each group of transactions is called a block. Blocks are secured by Bitcoin miners and build on top of each other forming a chain. This ledger of past transactions is called the blockchain. The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
Just when it seemed that things couldn’t get any worse, they did. As mining costs were rising, bitcoin prices began to dive. The cryptocurrency was getting hammered by a string of scams, thefts and regulatory bans, along with a lot of infighting among the mining community over things like optimal block size. Through 2015, bitcoin prices hovered in the low hundreds. Margins grew so thin—and, in fact, occasionally went negative—that miners had to spend their coins as soon as they mined them to pay their power bills. Things eventually got so grim that Carlson had to dig into his precious reserves and liquidate “all my little stacks of bitcoin,” he recalls, ruefully. “To save the business, we sold it all.”
Bitcoin's price is also quite dependent on the size of its mining network, since the larger the network is, the more difficult – and thus more costly – it is to produce new bitcoins. As a result, the price of bitcoin has to increase as its cost of production also rises. The Bitcoin mining network's aggregate power has more than tripled over the past twelve months.

The trick, though, was finding a location where you could put all that cheap power to work. You needed an existing building, because in those days, when bitcoin was trading for just a few dollars, no one could afford to build something new. You needed space for a few hundred high-speed computer servers, and also for the heavy-duty cooling system to keep them from melting down as they churned out the trillions of calculations necessary to mine bitcoin. Above all, you needed a location that could handle a lot of electricity—a quarter of a megawatt, maybe, or even a half a megawatt, enough to light up a couple hundred homes.

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.
You can buy bitcoins at online exchanges similar to a paypal account. Companies like Coinbase allow you to buy bitcoin with a credit card along with wire transfers, checks and ACH. You can also use professional exchanges like Coinbase Pro that allow for institutional investors and experienced traders to trade in high volumes in a variety of cryptocurrencies with minimal fees.
Hot wallets refer to Bitcoin wallets used on internet connected devices like phones, computers, or tablets. Because hot wallets run on internet connected devices there is always a risk of theft. Think of hot wallets like your wallet today. You shouldn’t store any significant amount of bitcoins in a hot wallet, just as you would not walk around with your savings account as cash.
The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted.[81] As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks (also called confirmations of the given block) increases.[64]
