With the meteoric rise in popularity of Ethereum, cryptocurrencies and blockchains are back in the news again.Graphics card prices have soared with the promise that those who have the computers and know-how to do some serious mining can take home huge sums in a Bitcoin-like gold rush to snatch up as much virtual currency as possible.And is it worth your while getting started?These days you can waste a weekend and a month’s wages on building a machine with four graphics cards purring away in a row and still not make a profit.GPUs are now established as the mining processors of choice in most situations—graphics cards are even built for and marketed towards miners now—basically because they’re better at doing lots of laborious, repetitive tasks, whereas CPUs are better suited to switching between many tasks quickly.You probably won’t get rich

The price of bitcoin is up over 250% since last year, but acceptance of the cryptocurrency as a form of payment among top merchants has declined.A research note out Wednesday by a group of analysts at Morgan Stanley led by James E Faucette said "bitcoin acceptance is virtually zero and shrinking," despite its impressive appreciation.According to the bank, last year bitcoin was accepted at five of of the top 500 online merchants.Today, only three of the top 500 merchants accept bitcoin as a form of payment."The disparity between virtually no merchant acceptance and bitcoin’s rapid appreciation is striking," the analysts wrote.The investment bank outlined three reasons for the decline in bitcoin acceptance among merchants.
But some investors are still optimistic and are prepared to ride it out.Aaron Batalion, a partner at Lightspeed Venture Partners, said he expected to see more 50% price jumps in ether, with big returns down the road."Over the next five to 10 years, I believe it will be worth 10 or 100 times its current value," Batalion said.Jason Calacanis, an early investor in startups including Robinhood and Uber, recently tweeted: "I think I need to own some Etherium -- what % of net worth would you allocate to crypto as a 46 year old with stable income?"Matt Galligan, a serial entrepreneur and investor in ether, said he was also looking to the five-year mark, when he expects the platform to have matured to the point when it has a lot of uses.It's a blockchain similar to the one underlying the bitcoin cryptocurrency that records information chronologically and publicly.
This week, Mark Karpeles, the CEO of Bitcoin trading site Mt Gox pleaded not guilty on charges of embezzlement.Once the world’s biggest Bitcoin exchange, Mt Gox fell from grace following the loss of hundreds of millions of dollars in one of the biggest cryptocurrency scandals to date.Founded by Jed McCaleb sometime in the 00s, Mt Gox began life as an site for Magic: The Gathering Online fans to exchange cards.The name of the site comes from an acronym for “Magic: The Gathering Online eXchange.”The site went from game cards to Bitcoin exchange fairly quickly.In McCaleb’s own words, cards were only traded on the original Mt Gox site for three months.
Russian cybercriminals are targeting users of the cryptocurrency Ethereum with a deluge of phishing attacks, and have so far made almost $700,000 in just six days.Many Ethereum users are part of online communities where they can discuss issues about cryptocurrencies.Instead of using forums, many mining pools, wallet services and information sites now host chatrooms using the customisable cloud-based chat messaging software Slack.Slack has multiple channels, so developers of the wallets and mining pools can chat in private channels, while also supporting public channels where any user can ask questions, get support and chat generally about any topic.Cybercriminals are capitalising on these Slack communities by infiltrating them and impersonating the software's official chatbot Slackbot to send fake custom messages from administrators to all members of a Slack team.Tens of thousands at risk

Everyone’s been talking about Cryptocurrency for the last few weeks, and it’s not hard to see why.But a turning point is coming soon, and it’s going to rattle the cryptocurrency community.Before we get to that, we’ll talk about how mining for Bitcoin has created a supply shortage of mid-range GPUs, something we saw a few years ago with AMD cards as well.Miners are buying them up for their power efficiency and high hash rate, as well as their appealing sub-$200 price point.That means AIB partners have completely run out of stock, and individual users have been taking to eBay and other secondary markets to sell their GPUs for well over face price.Part of this newfound enthusiasm comes from a totally new cryptocurrency, Ethereum.
Cryptocurrencies need to be regulated or they risk going out of control as more people invest in these digital assets, the head of a major Chinese bitcoin exchange platform warned on Tuesday.Bitcoin and ethereum, two popular cryptocurrencies, have seen rapid price swings in recent months.In May, a 19 per cent price fall for bitcoin saw nearly US$4 billion in value wiped off.Last month, the price of ethereum crashed as low as 10 cents from around US$319 in about a second on the GDAX cryptocurrency exchange.Because there’s bullishness in the market, some predict bitcoin’s price to soar as high as US$100,000 in a decade.“I think regulation is much needed for this new asset class because otherwise it’ll run amok from society,” Bobby Lee, CEO of exchange BTCC, told CNBC’s “Squawk Box.”
You’re in luck, as AMD and Nvidia have teamed up with their hardware partners to produce graphics cards dedicated to the lucrative art of cryptocurrency mining.The move is presumably to help keep the gaming and professional markets saturated with products given that miners can at times scoop up the vast majority of available high-powered, low-cost graphics cards, leaving supplies scarce and overpriced.That said, these cards are built to run 24 hours a day, seven days a week.That means AMD, Nvidia, and their partners had to go back to the drawing board to provide long-lasting products built with high endurance components to handle the the ongoing cryptocurrency mining process.That all said, we’ve broken our list into two sections: listed products, and cards that are supposedly hitting the market over the next two months.Ready to find your next graphic card for mining?
As the price for Bitcoin rises and falls dramatically, more users are wondering how they can get in on the action — and for good reason.Earning a few Bitcoin, or Ethereum, or any of the other cryptocurrency, could mean thousands of dollars in profit, and your home gaming machine may be able to churn them out using some simple software.Are you thinking about setting up a mining rig?Are you already swimming in a Scrooge McDuck-style room full of them?Let us know in this week’s reader poll.How interested are you in cryptocurrency?
Ethereum is under pressure on Monday.The cryptocurrency is down 9.9%, at $215 an ether, and is trading at its lowest level in more than a month.The cryptocurrency has had a rough go of things as of late.It has fallen more than 45% since reaching a record high of nearly $400 on June 13 amid chatter of a cryptocurrency bubble.First, the tech billionaire Mark Cuban suggested that Ethereum's rival, bitcoin, was in a bubble."I think it's in a bubble.
Bitcoin is flirting with a break below $2,500 a coin.The cryptocurrency trades down 3.7% at $2,510 and is threatening its lowest close since June 27.It's rival, ethereum is also under pressure, down 8% at $244.Friday's slide comes amid a relatively quiet week for bitcoin.It's price has been locked in a range between $2,474 and $2,639 since Monday.That's the day when Sheba Jafari, the head of technical strategy at Goldman Sachs, warned in a note to clients that bitcoin could fall as low as $1,857 before surging as high as $3,915.
That ultra-powerful Bitcoin or Ethereum mining system you're running uses enough electricity to power a U.S. household for days.Today’s cryptocurrencies are worth a great deal of “real” money.Both Bitcoin and Ethereum, the two most widely adopted cryptocurrencies, are close to their all-time highs in value, and that’s creating some real consequences that might not be completely obvious and intuitive at first glance.Two such consequences are based entirely on the fact that mining cryptocurrency is incredibly compute-intense and requires powerful components to be profitable.The first such impact has been to devastate the supply of the midrange and high-end GPUs that are used for mining and to dramatically increase their prices if available inventory can be located.The other impact is that the use of ultra-powerful mining systems with multiple GPUs sucks down some serious electricity and is resulting in some pretty impressive statistics, as Digiconomist reports.
south Korean Bithumb is the world's fifth-largest cryptocurrency marketplace.It forced authorities investigating after telling the public that hackers had access to its databases and stole more than 30 000 personal customer information.Bithumb tell you that the database you uncork was already in February, but this was noticed only 29. June.according to the BBC, hackers struck one Bithumbin the employee's computer, and access it through valuable customer information accessed.Bithumb announced on its website that the stolen data did not contain passwords.Ten Bithumbin however, customers have told us that they had received text messages and phone calls, which they believe to be the Bithumbin normal operations.
Digital currencies like Bitcoin are very hot right now, and hackers are apparently looking to take advantage of that, as one of the largest Bitcoin exchanges in the world was just hacked.Bitcoin and other cryptocurrencies surged in the past few months, which explains why people with malicious intentions would be looking to steal this precious virtual coin.According to Yonhap News, hackers hit Bithumb, compromising 30,000 accounts.That represents 3% of the exchange’s customers.It’s unclear how much money, if any, was stolen, but some people said they lost money in the attack.Bithumb realized last week that one of its employees’ home personal computers was hacked.
The alternative fundraising option has been used to raise more than $500 million in funding this year alone, but it has gotten a reputation for unfinished products and untested teams raising gargantuan sums.In doing so, it become the most established tech company to date to take this financing route.The company, which has raised over $20 million to date from traditional VC investors, held the token sale to raise capital to develop a decentralized payment platform — Omise Go — that it hopes will disrupt the current banking system.Beyond peer-to-peer payments, the company plans to sign up retail partners to extend its utility into purchases, and open the system up to other payment players, too.That’s much like a software license in traditional thinking, and it mirrors a wider move by Ethereum founder Vitalik Buterin, who is working on ‘Casper’ proof-of-stake functionality for the cryptocurrency.The startup provided a $100,000 grant to the Ethereum Foundation’s Devgrants program in 2015 — becoming one of its first donors alongside Microsoft — before identifying a business opportunity for the technology with Omise Go.
If you're looking to build or buy a new PC, then you might want to get a move on before prices rise even further.Building or buying a new PC has been a bit more expensive over the last several months due to a number of complicated factors.The production of solid-state disks (SSDs) has struggled to keep up with demand, the GPU market has been slammed by cryptocurrency miners buying up all of the available stock of midrange and high-end cards, and now DRAM pricing has become a sore spot, with a number of manufacturers scaling back on production for a number of different reasons.Now, a bit of bad luck promises to drive up prices even further, as DRAM maker Inotera (aka Micron Technology Taiwan) has shut down operations at its Fab-2 plant in Taiwan, as Evertiq reports.The shutdown was prompted by contamination of equipment caused by a faulty nitrogen gas dispensing system in the facility, which led to contamination of the DRAM wafers themselves.Each wafer produces a number of individual DRAM chips, and the Fab-2 plant makes a total of about 60,000 wafer starts a month.
Just as South Korea is reportedly getting ready to regulate and legalize cryptocurrencies like Bitcoin and Ethereum, news have emerged that Bithumb, the largest cryptocurrency exchange in the country has been hacked.Data from 30,000 customers has been compromised and according to the BBC, the data is being used to fool users into letting thieves steal funds from their accounts.In a separate report BraveNewCoin explains that Bithumb users were victims of "voice phishing," where someone phoned them up saying they worked for Bithumb and scammed them out of funds.The breach is reported to have occurred in February, and is said to have involved an employee's home PC rather than computer servers at the firm's headquarters.Bithumb says it discovered the breach on June 29 and reported it to the authorities the next day.The exchange claims that the number of affected people represents approximately three percent of customers.
As if you needed yet another reminder -- if someone calls you up and asks for your password or other private information, don't give it to them.It’s easy to get a bit discouraged lately when it comes to securing our personal data.Cybercriminals use a variety of electronic means to break into systems, whether it is our own PCs or those maintained by the hundreds of companies with which we do business.Sometimes, it is the combination that does the trick — a breach in an individual’s PC serves as a gateway to organizational data and results in our information making its way into the wild.Such seems to be the case in an attack on the Bithumb cryptocurrency exchange.The news comes via Hot for Security, based on information from some local reports in Seoul, Korea where the attack occurred.
