How Does Bitcoin Work?
This is a question that often causes confusion. Here's a quick explanation! As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once. The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography . A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining . Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions Continue reading >>
What Is Bitcoin? A Guide For The Confused.
What to know about the crypto-craze before it implodes. Maybe it was those stories you heard Lamborghinis and second mortgages, fortunes made and lost off of something you didnt even really know existed until six months ago. Maybe its those eye-popping charts you keep seeing, the ones that go $5,800 per unit to $19,000 per unit in just one month and the other ones that go in the opposite direction in just one week. Maybe all of your friends are constantly watching their phones, tracking their own investments, celebrating their newfound riches, freaking out about their sudden, sharp losses, and you just hate feeling left out. However you heard about it, it is now clear that this is at least something you should know about whether to invest, or just to inform your Schadenfreude. The problem is, well, what is a bitcoin, exactly? Secretly, you know you dont understand the thing, even though you may pretend to. Isnt it mostly for buying drugs? Where would I even buy one? Why would I want to? And isnt it already too late to be asking these questions, let alone actually investing in it? All right. Seriously. Remind me what a bitcoin is? A bitcoin is one unit of an anonymous digital currency called, yes, bitcoin. Hang on: anonymous digital currency? Thats what it was built to be, at least a theoretically untraceable and unhackable version of PayPal, more or less. But so many people got so excited about buying into the system that a market developed around buying and selling it with bitcoin becoming less important as a currency than as a commodity, like gold. You can still buy things in bitcoin (like you can with gold, sort of), but many more people are now using it as an investment vehicle. So bitcoin is a currency and a commodity? Something like that. Fundamentally, bitcoin i Continue reading >>
Bitcoin For Beginners And Dummies! Easily Understand All About Btc!
Explaining Bitcoin So You Can Actually Understand It To start, do not let the title of this piece make you feel any less of a human being or think that you are in fact a bitcoin dummy. That is not the case! Bitcoin is complex. There have been several very intelligent computer programmers and system developers (We are talking people who have invented the very technology that allows us to even get online!) who are on record as saying that they even have trouble understanding Bitcoin fully. Bitcoin is the first ever invented digital currency. It works the basis of the blockchain technology. It is continuously being created through a process called mining that involves computers solving cryptographic puzzles. Each block has its own cryptographic puzzle, and the unique solution represents 1 Bitcoin and the current state of all pending transactions. Using encryption techniques is how it is created and how transactions are verified as legitimate and recorded to the ledger. Operating independently of a central bank means that there is no person, company, government agency or any other single entity that controls bitcoin, it is governed by the very people who use it. But before we can delve into the peculiarities of Bitcoin we need to lay some foundations. Imagine you have a letter, cut it to little pieces and scramble them. By doing so you are encrypting the information that is contained in the letter. Meaning that when someone stumbles upon the scattered pieces, they would not be able to understand anything. That is until they decipher, decrypt the message by placing the pieces in the right order. This visualization of sorting algorithms explains the process best. Blockchain quite resembles a database. However, while traditional databases have a couple of locations where the Continue reading >>
How Can I Invest In Bitcoin?
Andy wants to know how to invest a few hundred pounds in bitcoin. Its not hard to buy bitcoins, but whether they are an investment or a gamble is another matter ... If you are investing, does bitcoin have an intrinsic value, like gold? To me, bitcoins look more like tulip bulbs.Photograph: Benoit Tessier/Reuters Andy wants to know how to invest a few hundred pounds in bitcoin. Its not hard to buy bitcoins, but whether they are an investment or a gamble is another matter ... Last modified on Thursday 29 June 2017 14.40EDT How can I invest in bitcoin? Id like to invest a few hundred pounds. Andy There are at least three ways, though only one of them looks rational today. First, you could mine your own bitcoins . Second, you could buy some from an exchange. Third, you could buy shares in a fund that has invested in bitcoins. Please note that answering your question is not a recommendation, and I am not qualified to give advice on investments. However, as electronic payments expert Dave Birch put it to me on Twitter : one doesnt invest in bitcoin, one gambles on bitcoin. The problem is that people can make money by buying things that are essentially worthless, such as used postage stamps, Beanie Babies, and (historically) tulip bulbs. Tulipmania operated on the bigger fool theory, also known among stock traders as momentum investing . For example, tulip bulb prices may be insane but they keep going up. I may be a fool to buy them, but I expect a bigger fool to buy them from me. Simply replace buy low, sell high with buy high, sell higher. This works until you run out of fools. However, you can buy things that dont depend on bigger fools appearing, such as land and gold. Their prices may vary dramatically, but over the long term, they retain real value. When tulip bulb pric Continue reading >>
Bitcoin: Seven Questions You Were Too Embarrassed To Ask
Sign up or login to join the discussions! Bitcoin: Seven questions you were too embarrassed to ask We're resurfacing this explainer to shed some light on the recent bitcoin drop. This explainer originally ran in early December. With continued high interest in bitcoin, we're republishing it with updated prices. This week, bitcoin has gone through a wrenching selloff , falling from a high of $19,500 earlier this week to below $13,000 on Friday. Want to really understand how bitcoin works? Heres a gentle primer In recent months, the currency's astonishing gainsit was worth less than $1 in early 2011and subsequent decline has caused a lot of people to wonder if they should be paying attention to the technology. While almost everyone has heard of bitcoin at this point, many people are fuzzy on the details: what is a bitcoin, exactly? How do I buy some? What would I use it for? We're here to help. Read on for a beginner's guide to bitcoin. We'll explain what bitcoin is, how it works, and what ordinary people should know about the technology. Chris Ratcliffe/Bloomberg via Getty Images The term bitcoin actually refers to two different things. Bitcoin is a payment networklike MasterCard is a payment network. Bitcoin also refers to the currency of the bitcoin networkmuch like MasterCard uses dollars in the United States. What makes bitcoin different from MasterCard, PayPal, and other payment networks that existed in 2008 (when bitcoin was invented) is that bitcoin was the world's first payment network that's completely decentralized. The MasterCard network is operated by MasterCard Inc., but there's no Bitcoin Inc. in charge of the bitcoin network. Rather, it's a peer-to-peer network that maintains a shared transaction ledger called the blockchain. Inventing a new currency wasan Continue reading >>

A Beginner's Guide To Investing In Bitcoin And Other Cryptocurrencies
A Beginner's Guide to Investing in Bitcoin and Other Cryptocurrencies By Jacob Weindling | December 1, 2017 | 10:22am While you normies were enjoying Thanksgiving, those of us who have pledged loyalty to our new digital deity were losing our collective minds. The entire cryptocurrency market shot up to all-time highs across the board, seemingly thanks to the fact that South Koreas second largest bank tested bitcoin wallets, an influx of new cryptocurrency investors join the market every day, plus the expectation that a bunch of big money will enter the market when the hedge fund CME and the NASDAQ add bitcoin futures in the coming months. I mean, look at this year-to-date bitcoin chart. This is nuts. We are definitely in a bubble. But you can still make money in bubbles. The phrase used by those of us who have jumped in on this supposed rocket ship is moonward, and given the angle of that bitcoin chart, it feels like were at least in the troposphere. It seems like its impossible to lose money in crypto right now, which creates FOMO (fear of missing out) that has surely fueled this astounding rise. There will no doubt be a proportional correction to this wild rally (and some of it has already happened), so buying right now may not be the best move (I am not a financial advisor nor a cryptocurrency expert, so consider this my legal disclaimer that you should obviously not mortgage your house because some guy on the Internet wrote a thing). Bitcoin is now one of the 30 or so largest currencies in the world, and it looks to be dragging several other cryptocurrencies up along with it. Despite all this progress, cryptocurrency is still in an incredibly early stage. While bitcoin may look expensive at around $10,000 per coin, thats a bargain compared to the $55,000 per coin t Continue reading >>
Bitcoin: A Simple Guide To Digital Currency | Wired Uk
WIRED has been reporting on digital currency Bitcoin for several years, but in the past few months, a single bitcoin's trading value has swung significantly making it a regular fixture in headlines. Despite this, there remains a lot of confusion about what bitcoins are, how to use them and whether or not we are in a Bitcoin Bubble. Here's our simple guide to Bitcoin. Bitcoin is a peer-to-peer electronic cash system or "cryptocurrency" that doesn't rely on trusting one central monetary authority and allows for anonymous, untrackable and untaxable transactions. The idea was first discussed by members of the cypherpunk mailing list and then a workable system which used a distributed database spread across the nodes of a peer-to-peer network (a little like the one that underpins Bittorrent) that could keep track of transactions secured by cryptography was outlined by a programmer called Satoshi Nakamoto in a paper in 2008 and built in 2009. It seems that Bitcoin is an awkward combination of the two. The commodity value of bitcoins is linked to their currency value, but the more they become like a commodity, the less useful they are a currency. Anyone can install Bitcoin's mining software, which then uses the computer's processing power (using the CPU or GPU) to carry out intensive calculations you can think of it like trying to search for prime numbers. Lots of people might be working on the same unit of work - a computationally complicated problem. The aim is to find a certain sequence of data, called a "block", that produces a particular pattern when the Bitcoin "hash" algorithm is applied to the data. Whoever's computer manages to do that will win bitcoins. Psychology explains why your friends can't shut up about bitcoin When it started out, it was relatively easy to mi Continue reading >>
How To Buy Bitcoin: A Guide For Beginners
How To Buy Bitcoin: A Guide For Beginners Here is a simple guide on How To Buy Bitcoin: Bitcoin is a virtual type of currency that is owned by no government, bank or nation. It is steadily increasing in value as more and more people purchase it , and slowly, certain businesses are starting to accept it. But it remains highly volatile, and this alone makes it impractical as a tool of commerce. However, these are early days. The world is turning to face technologies like Bitcoin and the blockchain that makes it work, and many of the worlds biggest banks and consulting firms are working hard to set up policy and case studies to be ready when the rest of the world flips the switch, and Bitcoin becomes as big the hype suggests. If you want to buy some, its pretty easy. But first lets make sure you have somewhere safe to keep it. So we created this how to buy bitcoin guide for you as non legal or investment advice but a basic guideline for some important pointers. Youll need a wallet. Not a nice leather billfold, because Bitcoins are not physical. There are no coins and no paper bills involved. It is all virtual. The Bitcoin wallet is an app that you can download to your phone, and your computer. It contains two 16-digit passwords: one is called a public key, and the other is a private key. Quite simply, when you buy Bitcoin, your wallet sends your public key information to the vendor, the same way you would enter a credit card number into an online form. The public key tells the vendors app where to send the Bitcoin amount. The private key is the password you employ to confirm the transaction from your end. This one-time code is reviewed by the computers on the blockchain, who then approve the transaction unanimously as representing your receipt of a certain amount of Bitco Continue reading >>
Bitcoin For Beginners: Everything You Need To Know
Bitcoin for Beginners: Everything You Need to Know Still confused about bitcoin? Don't know what cryptocurrency is? Can't figure out why anyone would want to make a chain out of blocks? You've come to the right place. The biggest investing story of 2017 has undoubtedly been the incredible take-off of cryptocurrencies. While there have been dozens of initial coin offerings (ICOs) and several cryptocurrencies have risen to various levels of prominence this year, the undisputed champion remains bitcoin. Yet, while there is plenty of hype and buzz surrounding this cryptocurrency, a great deal of confusion still exists concerning what exactly bitcoins are, how they might prove to be useful, and whether they truly represent a once-in-a-lifetime investment opportunity or if there is a bitcoin bubble ready poised to burst. With this sense of confusion in mind, here is a brief primer for investors wanting to know more about the biggest investing story of 2017. Bitcoin is the king of cryptocurrencies but does it make for a good investment? Image source: Getty Images. It's probably best to begin by defining the terms. Bitcoin is a type of cryptocurrency. One of the better definitions I've found is from OxfordDictionaries.com, which helpfully defines cryptocurrencyas "a digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer of funds, operating independently of a central bank." It might be useful to think of bitcoin as a digital currency that can be used to complete a transaction between two parties without involving a middleman. In other words, it enables direct, private transactions between users, with virtually no transaction costs; something it can accomplish because it is powered by blockchain technology Continue reading >>
Still Don't Get Bitcoin? Here's An Explanation For Five-year-olds
If you still cant figure out what the heck a bitcoin is, this simple explanation for a five-year-old may help you ... Were sitting on a park bench. Its a great day.I have one apple with me, I give it to you. You now have one apple and I have zero.That was simple, right? My apple was physically put into your hand.You know it happened.

As you see, this digital exchange is a bit of a problem.Sendingdigitalapples doesnt look like sendingphysicalapples. Some brainy computer scientists actually have a name for this problem: its called the double-spending problem . But dont worry about it. All you need Continue reading >>
Bitcoin: 3 Things To Know About Cryptocurrency Investing | Fortune
Bitcoin has been luring some investors with potentially huge rewardsand scaring others away with equally big risks. Should it be on your investment shopping list on Black Friday? The cryptocurrency can certainly be volatile. Earlier this month, for example, it plummeted 25% over five days after concerns grew that a new currency called Bitcoin Cash, which promises to speed up transactions, would make Bitcoin itself a less attractive payment option. That fear didnt last long. Over a subsequent two-day span, investor sentiment reversed and the price jumped up 18% from its lows; by Thanksgiving, Bitcoin had soared to new highs . Not many investments engender the differences in opinion that Bitcoin and other cryptocurrencies create. Its that volatility, and uncertainty about the technologys long-term viability, that breeds whirlwind days. The currency has turned evangelists and hackers into paper millionaires overnight, while others see it as a fad, doomed to fade as countries add regulations onto whats currently a stateless, bankless Wild West of payment tools. Still, its hard to argue with the short-term results. On New Years Day, a single Bitcoin was worth $964; by Black Friday morning its value had passed $8,200, a gain of nearly 800%. Taken together, the market capitalizations of all the worlds cryptocurrencies, including other prominent players like Ethereum and Ripple, have risen even faster this year. This growth has pushed mainstream institutions to take notice and capitalize. CME Group, the worlds largest options and futures exchange owner, announced it would offer Bitcoin futures by the end of the year. That move would give Bitcoin a level of credibility that established currencies have, and also provide an infrastructure for developing exchange-traded funds (ETF Continue reading >>
How To Invest In Bitcoin: A Step-by-step Guide | Money
Bitcoin has captured Americas imagination. Whether or not the cryptocurrency will ultimately turn out to be a good investment or just a passing fad remains to be seen. Indeed, in the past several months Bitcoin prices have enjoyed a run-up that makes the 1999 tech bubble look staid by comparison. That excitement the promise of sudden riches or sudden ruin has a lot of people wondering how a bitcoin investment actually works. If thats you, heres a step-by-step guide on how to trade bitcoin. But first Like any speculative investment, buying bitcoin at sky-high valuations is risky business. If youre asking, Is it smart to invest in bitcoin? you might do well to heed this advice from billionaire investor Mark Cuban, who told MONEY , Its still very much a gamble. You need to know that your bitcoin investment might lose money. If youre not prepared to face that prospect, bitcoin investment might not be for you. Youd be in good company in that case, anyway. Jack Bogles bitcoin investment advice is pretty simple, and blunt: You should avoid Bitcoin speculation like the plague. And this is coming from the guy who founded Vanguard, so he knows a thing or two about investments. The other risk to keep in mind if you plan to invest in bitcoin, aside from the overall volatility of the cryptocurrency, is of a cyber attack. Hackers descended on digital currency exchange Bitfinex on Tuesday, less than a week after cybercrooks made off with $70 million in a separate heist. If youre aware of the risks and still willing to take the plunge, this is what you need to know about investing in bitcoin: Cryptocurrencies exist in an unregulated, decentralized digital sphere without involvement by (or protection via) a central bank. This is part of bitcoins appeal. People or entities can buy and s Continue reading >>
