Bitcoin Theft: 5 Common Threats, Hacks, And Scams | Fortune
A visual representation of the digital Cryptocurrency, Bitcoin on October 23, 2017 in London, England. A bitcoin mining service was hacked to the tune of $64 million this week, underscoring once again how the world of digital currency attracts scammers and thieves. Such stories can scare off amateur investors who fear bitcoin isnt just volatile, but that its insecure. This isnt really fair to bitcoin. The reality is bitcoin is secure, and ordinary people can protect it without much effort. The real problem is not everyone understands how bitcoin works, which leads them to make choices that expose them to theft. This will become clear in the examples below, which describe five common ways that thieves make off with other peoples bitcoin. But first theres a short explanation of how bitcoin works and why its secure (skip this if youre already familiar). How Bitcoins Technology Protects Your Funds You can think of bitcoin as money that comes wrapped in a safety deposit box. The question then becomes whether you want to operate that box yourself, or entrust a third party to do it for you. Most ordinary investors choose the latter option, buying, and storing their bitcoin with a service like Coinbase. This is a sensible option since those services rely on the security features built into bitcoinjust like you would do if you hold the bitcoin yourself. The other option is to acquire a bitcoin wallet for yourself. This entails keeping track of two strings of keyboard charactersknown as a public key and a private key. You can think of the public key like a deposit slot for your safety deposit box where anyone can give you bitcoin, while the private key is a secret way to open the box that only you should know. Bitcoin is designed so that its basically impossible to guess the pri Continue reading >>

Verhage: Bitcoin and other crypto-assets have had crazy runs this year. As I type this, bitcoin is closing in on $12,000 after starting the year around $1,000. Elaine, what have you seen as the big drivers for this years run up in price? Ou: Earlier in the year, there was a lot of hype around Initial Coin Offerings as a way to raise money. People were going totally overboard with marketing. The only way to buy into these tokens was to first acquire bitcoin or ether, so demand for ICOs created demand for bitcoin and ether. This is still going on, although the craziness has died down a bit. At the same time, were seeing increased interest among institutional inv Continue reading >>

Hackers Have Stolen Millions Of Dollars In Bitcoin -- Using Only Phone Numbers
Hackers Have Stolen Millions Of Dollars In Bitcoin -- Using Only Phone Numbers Just after midnight on August 11, self-professed night owl Jered Kenna was working at home in Medellin, Colombia, when he was notified the passwords had been reset on two of his email addresses. He tried to set up new passwords himself by prompting the email service to send him text messages containing a code but they never arrived. So I called the company to make sure I hadnt forgotten to pay my phone bill, and they said, you dont have a phone with us. You transferred your phone away to another company, he says. A hacker had faked his identity and transferred his phone number from T-Mobile to a carrier called Bandwidth that was linked to a Google Voice account in the hackers possession. Once all the calls and messages to Kennas number were being routed to them, the hacker(s) then reset the passwords for Kennas email addresses by having the SMS codes sent to them (or, technically, to Kennas number, newly in their possession). Within seven minutes of being locked out of his first account, Kenna was shut out of of up to 30 others, including two banks, PayPal, two bitcoin services and, crucially, his Windows account, which was the key to his PC. While this would wreak havoc on anyones life, it had especially disastrous consequences for Kenna. Im an early bitcoiner, he says. I dont think you have to say anything else. Kenna was so early in bitcoin that he remembers when he would plug his computer into the network and see only four other computers running it. Now, there are more than 5,000. Computers supporting the network are slated into a competition to win bitcoin roughly every 10 minutes. In the early days, the payout was 50 bitcoin each time; now its 12.5. Kenna recalls that at a certain poi Continue reading >>

The most famous cryptocurrency - Bitcoin was developed in 2009 by developer Satoshi Nakamoto. The payments in the system are recorded in a public ledger using its own unit of account, which is also called cryptocurrency. Payments work peer-to-peer without a central repository or single administrator, which has led the US Treasury to call cryptocurrency a decentralized virtual currency. Although its status as a currency is disputed, media reports often refer as a cryptocurrency or digital currency. Bitcoin are created as a reward for payment processing work in which users offer their computing power to verify and record payments into the public ledger. Called mining, individuals or companies engage in this activity in exchange for transaction fees and newly created cryptocurrencies. Besides mining, cryptocurrencies can be obtained in exchange for fiat money, products, and services. Users can send and receive cryptocurrencies electronically for an optional transaction fee using wallet software on a personal computer, mobile device, or a web application. Bitcoin as a form of payment for products and services has seen growth,and merchants have an incentive to accept the digital currency because fees are lower than the 2-3% typically imposed by credit card processors. The European Banking Authority has warned that cryptocurrency lacks consumer protections. Unlike credit cards, any fees are paid by the purchaser not the vendor. Cryptocurrencies can be stolen and chargebacks are impossible. Commercial use of Bitcoin is currently small compared to its use by speculators, which has fueled price volatility Continue reading >>

Bitcoin Won't Last In World Of Finance, Warns Nobel-winning Economist
Bitcoin won't last in world of finance, warns Nobel-winning economist Davos speakers round on cryptocurrency as Robert Shiller calls it a clever idea with an impermanent future Last modified on Thu 25 Jan 2018 17.01EST Bitcoin medals made at a Tokyo factory in Japan.Photograph: Tomohiro Ohsumi/Getty Images The Nobel prize-winning economist Robert Shiller has said bitcoin will not be a permanent feature of the financial world, as politicians indicated that a clampdown on cryptocurrencies was coming. Speaking at the World Economic Forum in Davos on Thursday, Shiller hailed bitcoin as a really clever idea. But although he was impressed with the technology behind it, he was concerned that it had gone viral as a currency. I tend to think of bitcoin as an experiment. It is an interesting experiment, but its not a permanent feature of our lives, said Shiller, who has previously warned that the bitcoin price could collapse. We are over-emphasising bitcoin, we should expand it out to blockchain, which will have other applications. Theresa May said in Davos that she was concerned that criminals were taking advantage of digital currencies, which can be used to anonymously transfer funds. In areas like cryptocurrencies, like bitcoin, we should be looking at these very seriously, May told Bloomberg. The US treasury secretary, Steven Mnuchin, also flagged up concerns about misuse of digital currencies. My number one focus on cryptocurrencies, whether that be digital currencies or bitcoin or other things, is that we want to make sure that theyre not used for illicit activities, Mnuchin told CNBC. So in the US our regulations [say] if youre a bitcoin wallet, youre subject to the same regulations as a bank. South Korea has recently announced a clampdown on digital currencies.

What Is Bitcoin? A Step-by-step Guide For Beginners
What is Bitcoin? A Step-By-Step Guide For Beginners Angel Investors, Startups & Blockchain developers... If you want to know what is Bitcoin, how you can get it and how it can help you, without floundering into technical details, this guide is for you. It will explain how the system works, how you can use it for your profit, which scams to avoid. It will also direct you to resources that will help you store and use your first pieces of digital currency. Small wonder that Bitcoin emerged in 2008 just after Occupy Wall Street accused big banks of misusing borrowers’ money, duping clients, rigging the system, and charging boggling fees. Bitcoin pioneers wanted to put the seller in charge, eliminate the middleman, cancel interest fees, and make transactions transparent, to hack corruption and cut fees. They created a decentralized system, where you could control your funds and know what was going on. Bitcoin has come far in a relatively short time. All over the world, companies, from REEDS Jewelers, a large jewelry chain in the US, to a private hospital in Warsaw, Poland, accept its currency. Billion dollar businesses such as Dell, Expedia, PayPal, and Microsoft do, too. Websites promote it, publications such as Bitcoin Magazine publish its news, forums discuss cryptocurrency and trade its coins. It has its application programming interface (API), price index, and exchange rate. Problems include thieves hacking accounts, high volatility, and transaction delays. On the other hand, people in third world countries may find Bitcoin their most reliable channel yet for giving or receiving money. At its simplest, Bitcoin is either virtual currency or reference to the technology. You can make transactions by check, wiring, or cash. You can also use Bitcoin (or BTC), where you re Continue reading >>
