19 billion mining machines
It's a scam. Many Internet enterprises and network security enterprises believe that illegal "mining" has become a serious network security problem
with the rise of "cloud mining", the virtual machine has become the main use object of digital currency such as Monroe coin and Eli coin, and the situation of embezzling cloud computing resources for "mining" has also increased significantly; Security team monitoring found that "competing for mining machine" has become one of the important purposes of Botnet expansion; And found a new type of "mining" virus (mining XmR / Monroe), the virus spread wildly in two months, illegal "mining" profits of nearly one million yuan
extended information:
from a commercial point of view, the business model of mining can walk out of a "healthy road". As long as the "incentive money" is lower than the average cost of new users in the market, the business model will be reasonable and feasible
however, if the platform tempts users to participate with "no capital, no profit", it is worth being vigilant. The so-called "mining" opportunity provided by the platform is likely to be "digging a good hole" waiting for you to jump in
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. 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 money circulation. 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
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
Every 100 S4 bitcoin mining machines consume 900W of electricity per hour
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
What is a bitcoin miner? I often hear about bitcoin, bitcoin mining machine. Let's talk about bitcoin. Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power
The digital currency in the future is believed to be similar to bitcoin, but it is by no means a limited supply. But when the human ability to proce wealth can be completely matched by the computing power of the computer, the issuing speed of e-money is directly proportional to or slightly exceeds the computing speed of the computer to create moderate inflation. In the future, while mining, it is also creating value rather than wasting electricity. In the end, the small changes in proctivity of digital currency match the difficulty of computing power, which may be the final form of human currencybecause this process is similar to the gold mining process in real life, it is called "mining".
