They are both cooled by dual fans. A dry basement is an ideal location. This peak was reached on May 24 th Such tremendous growth has been spurred by major investment into Bitcoin mining technology and operations. Profits have accumulated where mining is most profitable China , with the result that several competing operations eg. KNC have been forced out of the industry. We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars.

Even with free electricity we cannot see how they will ever get this money back. The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market. With the block reward halving looming, the profitability of all but the most efficient operations will likely be challenged. Given that profits derived from the current generation of mining hardware are dwindling and will likely reach negative returns post-halving:. Can the new S9 change the game for smaller and hobby miners and restore their lost profitability?

Note: Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool. The first batch of S9s will be available for order directly from Bitmain from the 12 th of June. However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe.

Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future. The release cycle of a new generation of mining hardware every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs.

The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology. The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices. Although a 10nm process is on the horizon for , further increases beyond that remain theoretical. Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year.

Our guide on the best bitcoin wallets will help you get one fast and for free. Read it here! The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9. A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate.

Note that Power Cost will be specific to your location and that Difficulty changes every 2 weeks, usually to the upside…. Your Pool Fees will be determined by your mining pool; although the S9 is plenty powerful, a single unit is highly unlikely to find any blocks when solo-mining. Of course, such impressive results assume all factors stay constant which is hugely improbable in the ever-changing world of Bitcoin!

The cutting-edge manufacturing process is what makes the S9 the most electrically-efficient mining device to date. It uses a mere 0.

The S9 consumes about W more than the S7. Apart from the power supply, the S9 is a self-contained unit. It requires no connection to another computer to interface with other Bitcoin nodes.

The S9 performs reliably in any well-ventilated space, whether a single or several unit s kept in a spare room or hundreds to thousands of units in a large mining center.

On the other hand, the halving could bring about a higher Bitcoin price and reduced competition, increasing profitability. It is likely to remain profitable for far longer than previous generations of ASIC miner, although ROI cannot be guaranteed given the inherent unpredictability of Bitcoin mining.

Bitmain is regarded as one of the most influential companies in the ASIC mining industry. Halong Mining is no longer around. It seems they could not compete with the already established ASIC manufacturers, most likely because they could never fill their orders and get the partsd they needed to produce enough miners to make money. The DragonMint W power supply is strongly recommended, though not mandatory. Each miner requires its own individual power supply.

Professional mining hardware runs optimally at V, hence why mining farms step down their own electricity supply to V. In any case, it would be a good idea to buy the DragonMint power supply.

These PSUs will get the job done, but they are not ideal for optimum mining performance. Consuming merely 0. Keep in mind that exact power consumptions vary, especially depending on which power supply you are using. Take a look at the projected mining profitability of a single miner :. The Antminer R4 hashes at up to 8. BitFury was the first company to release 16nm chips. As the saying goes nothing good comes cheap. With all the awesome features that come with the Antminer R4 you would expect its price to be high.

Its price is among its cons because this may be too high for the average hobby miner. Once you setup your Antminer R4 you will see that its user interface has been well designed with the users in mind. All you have to do is enter your wallet address and mining pool settings before you start mining. It is also possible for you to customize settings such as the fan speed or the frequency.

With a hash rate of 8. Rest easy because most homes have an outlet that can handle Watts safely but also expect your electricity bills to rise significantly. Of course we assume that all factors remain constant which is almost impossible in the ever-changing world of Bitcoin. This means that the Antminer R4 will eventually produce a profit, but only if the network hash rate, Bitcoin price, and electricity costs stay the same.

All of those factors are a big IF, since the network difficulty almost always increases. So you are definitely taking on risk with this miner, and it may not be worth your time despite the many benefits it provides over other hardware. One of the most unique features of Antminer R4 is that it was designed to ensure the least possible sound with the maximum hash rate. Antminer R4 replaces the traditional fan with a rotary blade system. The traditional fan has been the biggest source of noise for other mining hardware.

Its fan speed is controlled automatically, ensuring that the noise is regulated. Bitmain recommends the use of an APW5 power supply. It also uses 28nm Xilinx programmable logic. It supports Gigabit Ethernet to ensure that mined blocks are submitted instantly.

Not only are the devices expensive but they also generate a lot of heat and noise, not to mention the amount of electricity they consume. Some of these problems mentioned above have been addressed and as a miner you can do it as a hobby while also making some money.

This home Bitcoin miner is not only a good fit for hobby miners but also helps to improve the decentralization of Bitcoin mining as a whole.

It's when websites decide to do it in the background, without your knowledge, that it becomes unethical. Assuming your computer doesn't have a malicious coin mining program installed, there are a number of ways to block coin mining while you browse.

If you suspect a website is using your computer to mine cryptocurrencies without your permission, you can simply block JavaScript altogether. The problem, however, is that this is a very aggressive way to block mining and will break many websites. Facebook, for instance, will not load without JavaScript enabled. If you don't want to use an ad blocker or just want to specifically block coin mining, there are a handful of extensions available.

These extensions work by blacklisting known domains and mining scripts. They're regularly updated and are among the best hands-off approaches to block mining. On the flip side, if you want to support a website by allowing it to mine, you can whitelist it. While browsers haven't yet adapted to blocking cryptocurrency miners or at least making them an opt-in option , some anti-malware software has. Malwarebytes, for example, offers cryptocurrency miner blocking in its premium subscription.

Be respectful, keep it civil and stay on topic. We delete comments that violate our policy , which we encourage you to read. Discussion threads can be closed at any time at our discretion.

The website keeps the cryptocurrency, and you get higher electric bills, % CPU usage that drags down your computer, and reduced battery life. Bitcoin mining with JavaScript has never been this easy. If you think you need to go through a tedious setup or chase the non harmful JavaScript code on the internet- you’re wrong. CoinIMP is the best JavaScript Bitcoin mining tool of Last year, my top choice for JavaScript mining was Coinhive. The block reward is what miners try to get using their ASICs, which make up the entirety of the Bitcoin network hash rate. ASICs are expensive, and have high electricity costs. Miners are profitable when their hardware and electricity costs to mine one bitcoin are lower than the price of one bitcoin.
