Mining machine news
when you buy a video card miner, go to a local computer dealer and buy a professional chip miner, usually on the mining platform
here are some introctions to the graphics card Mining:
the graphics card mining machine is a computer with 6 medium and high-grade independent graphics cards. The first display card miner is rx470 / rx480. Because it is too hot, AMD's display card manufacturers are in short supply, and the goods are scattered to a few pieces, so many of them are mining with gtx1060, and the 1060 is out of stock. They start mining with gtx1050ti 4G, but there are not many now
1060 is about 0.07 per day, power 1200W +, computing power 125 ~ 135mh / s
1050ti is about 0.05 per day, power 700W, computing power 75 ~ 85MH / s
basically, the price is directly proportional to the performance, maybe 1050ti is slightly ahead, but the combination of 1060 is recommended for single person and single mining
hand printing, without and paste, is adopted.
this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
Although the price of bitcoin has suffered a sharp drop before the Spring Festival, there are still some people who are obsessed with "mining". Therefore, mining equipment has become a hot spot, and some people have made a fortune
analysts from Bernstein, a well-known US investment bank, estimate that in 2017, the operating profit of a Chinese start-up company named bitmain in China may reach US $3 billion (about RMB 19 billion) to US $4 billion (about RMB 25.3 billion), which is equivalent to that of chip giant NVIDIA
However, it took bitmainland only four years to achieve such a high profit in one year, while NVIDIA spent 24 yearsbitmainland's operating profit may exceed US $3 billion
according to the conservative expectations of 75% gross profit margin and 65% operating profit margin, bitmainland's operating profit in 2017 is US $3 billion to US $4 billion, while NVIDIA's operating profit in the same period is US $3 billion. In a report released on Wednesday, Bernstein analysts said it took bitmainland only four years to achieve this goal, while NVIDIA took 24 years
According to Bernstein's report, each of the antminer bitcoin mining devices currently sold by bitmainland is worth hundreds to thousands of dollars. In addition, the company operates "mining pools" that allow participants to collaborate on bitcoin mining to rece costs. Bernstein estimates that bitmainland has 70% to 80% market share in bitcoin miners and ASICs
according to the daily economic news, the ethash algorithm currently used by Ethernet is based on the demand of graphics chip, which is suitable for PC mining, and the mining machine is not good at it. The market expects that bitmainland will soon launch a new mining machine with low energy consumption and high efficiency. A professional mining machine can be equivalent to several 8-graphics card mining machines. After the official launch, it is bound to impact the original PC mining market with graphics chips. At that time, because of "mining" and soaring chip prices are also expected to return to rationality
Mitch Steves, an analyst at RBC Capital, believes that the price of Ethernet currency has skyrocketed from $10 in early 2017 to $1000 now, and the possibility of exclusive mining chips is much higher than a year ago. Steves also pointed out that if bitmainland really sells chips dedicated to Ethernet coins, the mining efficiency will be far better than that of graphics chips, and at that time, it will take away the business of NVIDIA and AMD
according to the daily economic news, NVIDIA's financial report for the fourth quarter of 2017 released in early February found that the company's data center, including the sales of graphics processing units (GPU and graphics card), had an operating revenue of US $606 million in the fourth quarter, making it the second largest revenue source of NVIDIA. The chief financial officer of NVIDIA also mentioned that in terms of the overall demand for NVIDIA procts, the contribution of digital money market is difficult to quantify, but I believe the percentage contribution in the fourth quarter is higher than that in the previous quarter
It depends on the source of the mine. If it is an "open pit mine", the investment is relatively small. The main investment is the wages of workers and the cost of transportation road construction. If the ore is deeply buried, the investment needs to be larger. In addition, the acquisition of mining license is also a part of the investment, and this is the main part. If there is no mining license, the others are always empty
To sum up, the main investment costs are as follows:1, workers' wages
2, machinery and equipment
3, transportation road construction and maintenance costs
4, mining license fees
5, and other costs

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.
this is the data provided in a press release at the end of November last year. Of course, according to the current computing power, we can't dig so many bitcoins, and the revenue will be lower. Even tianhe-2 mining is a loss
after all, bitcoin mining is a professional business, it needs a professional bitcoin miner. And the update speed of bitcoin miner is amazing. Take the mainstream Avalon mining machine in the market as an example, it has been upgraded to three generations of chips, and the fourth generation will come out soon.
