An increasing number of websites have turned to embedded cryptocurrency mining to generate revenue in place of (or in addition do) ads. One of the problems with this approach is that websites are not always transparent about this. And in other cases, legitimate websites that have been hacked could be running mining software on visitors' PCs without their knowledge. This has gotten the attention of Google, which is considering ways to prevent mining software from running in its Chrome browser. Websites that take this approach use an online JavaScript-based miner called Coin Hive. What this does... Read more...
Something big is happening in the cryptocurrency market. Ethereum, the second largest digital coin behind Bitcoin, is receiving a major change to its codebase on Sunday, and nobody knows what exactly will happen. The update amounts to another hard fork, which for the most part have gone well for Ethereum miners and its investors. But there is always that unknown. "I expect that nothing will happen," Ethereum Foundation developer and designer Alex Van de Sande told CoinDesk. "Nothing happened with previous hard forks, except for one."Image Source: Flickr (BTC Keychain) The exception Alex refers... Read more...
It looks like another major hack has been perpetrated against a major company, this time the hack was of pay TV network Showtime's streaming platform, ShowtimeAnytime.com. The platform allows users with a subscription via a cable network to stream shows via a browser from anywhere. People with no TV subscription can also pay for the streaming service alone making it appealing to cord cutters. Word is that last week the ShowtimeAnytime platform was hacked and code created by Coin Hive that runs on JavaScript was inserted into the platform. Interestingly, this is the same Coin Hive code that was... Read more...
Abnormally high GPU pricing has been an issue for a long time now, but things really hit a peak when AMD launched its Radeon RX Vega series last month. Immediately, the graphics cards were nearly impossible to find, and those that were in stock were found with seriously inflated prices - sometimes with a nearly $200 premium due to price gouging merchants playing the supply and demand game. Unfortunately, it also appears that consumers looking at picking up an NVIDIA graphics card are also now starting to feel the burn of a higher street price. While AMD cards are often sought out first... Read more...
What is a blockchain? When considering cryptocurrencies like Bitcoin or Ethereum, it's best to first understand the underlying technology and framework that makes their existence possible. At its core, a blockchain is a what is described as a "shared ledger" technology that is used to record the complete history of transactions that have been made. More importantly, this ledger cannot be altered in any way, making it ideal for historical analysis and peer review. When it comes to everyday transactions -- be they financial, inventory or even account-based, traditionally, each party that is involved... Read more...
Bitcoin is living up to its billing as a volatile currency. It was a big deal last month when Bitcoin first flirted with a $2,900 valuation. Just a couple of weeks later, it jumped past the $4,000 mark, setting yet another new high in the process. More recently, Bitcoin has hit a rough patch, causing its value to fall as low as $2,915.15, its lowest level since it surge in early August.Cryptocurrency investors seemingly panicked in the wake of negative news this week. It started with JPMorgan Chase CEO Jamie Dimon calling cryptocurrencies like Bitcoin a fraud. Speaking at the Delivering Alpha conference,... Read more...
Update, 9/15/2017: We've updated our Ethereum mining benchmark numbers in this article to include AMD's recently released Radeon RX Vega graphics cards. Head here for that updated data or journey on for the full guide. Cryptocurrency mining is a big buzz topic in technology these days. And why not? Utilizing your computer to digitally mine what seems like free money only begs the question, "where do I sign up?" Your machine will actually be "mining" or processing transactions for a decentralized currency, the hottest variant of which is called Ethereum.  Poised to overtake the industry... Read more...
Just a day after JPMorgan Chase CEO Jamie Dimon unleashed a fury of attacks on Bitcoin (and cryptocurrencies in general), another salvo is incoming. It was reported last week by Caixin that China was contemplating shutting down cryptocurrency exchange trading, and further confirmation of that order arrived today. The news sent Bitcoin into another tailspin, extending its losses for a fifth straight day, its longest losing streak in over a year. BTC China, the second largest exchange in China, announced that as to today, it will no longer accept new user registrations. It also announced that the... Read more...
There has been a run on cryptocurrencies in the past year or so, especially when it comes to Bitcoin and Ethereum. The latter has especially been popular, with enthusiasts quickly gobbling up high-performance NVIDIA and AMD GPUs to bolster their mining efforts. While many enthusiasts and even some well-respected financial institutions have flocked to cryptocurrencies, one high-profile executive takes the stance of "Just Say No", to quote the late Nancy Reagan. JPMorgan Chase CEO Jamie Dimon isn't just down on cryptocurrencies like Bitcoin; he thinks that they are a fraud, plain and simple. JPMorgan... Read more...
There is some big money to be made in cryptocurrency mining, assuming the operation is large enough. That is especially true when the value of volatile digital currencies such as Bitcoin and Ethereum skyrocket, as both have done in recent times. Unfortunately, there are some undesirable side effects to the cryptocurrency boom—we all know about the shortage of graphics cards, but even more troubling is that some mining groups are exploiting PCs with malware for more firepower. The situation is getting worse, according to Russian antivirus vendor Kaspersky Labs. A new report by Kaspersky claims that... Read more...
NVIDIA’s GeForce GTX 10 Series and AMD’s Polaris family of Radeon GPUs have been popular with Ethereum miners since the start of 2017. Many of these cards have been in short supply, and the GPU market actually showed an uncharacteristic uptick in growth during Q2 because of this demand. With that in mind, all eyes are currently on AMD with its new Radeon RX Vega family of GPUs. We’ve already seen that the Vega 64 (and the Vega 56 in particular) excel at Ethereum mining once optimized. One redditor, however, has taken his optimizations to the extreme, allowing his Vega 64 to obtain a hash rate of... Read more...
ASUS is releasing a motherboard with 19 PCI-Express expansion slots, and no, it is not intended for gamers who want to play Crysis (or any other title). This one is aimed directly at digital coin miners as the cryptocurrency craze rages one. Like the California gold rush that lasted from 1848 to 1855, this cryptocurrency boom has modern day miners going out in search of riches, and more tools are being made available specifically for that purpose.Cryptocurrency mining is red hot at the moment. Two of the most popular cryptocurrencies are Bitcoin and Ethereum, both of which are trading at obscenely... Read more...
Ethereum (ETH) has risen to become hugely popular in the cryptocurrency world over a relatively short period of time. After first appearing on the radar screens of miners earlier this year, with valuations surpassing the $400 mark in June, ETH pricing is now hovering around $300. Mining enthusiasts have built their own dedicated machines for mining Ether, with many choosing mid-range NVIDIA and AMD hardware to get the most bang for the buck and performance-per-watt. As we mentioned in our Ethereum Mining Optimization Guide, we found that the NVIDIA GeForce GTX 1070 offers a relatively high hash... Read more...
The life of a cryptocurrency miner is fast and furious, especially if that person is mining Bitcoin, the most popular digital currency in existence. Consider that it was just two months when Bitcoin hit the $3,000 mark for the first time since it was introduced in 2009. Now just eight weeks later it is trading at around $4,300, hitting a new all-time high after activating a plan to speed up transaction times. Without getting into the somewhat complicated nitty-gritty details of cryptocurrency and the mining process, the relevant bit of info here is that Bitcoin recently split into two directions,...
