Types of virtual currency mining machine
bitcoin mining machine is the computer used to earn bitcoin
mining software is the algorithm of bitcoin
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all 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 the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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
extended data:
bitcoin has the following six characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Worldwide circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

secure payment. Qwc has no pre excavation and ICO, and adopts cryptonight algorithm (supporting mainstream mining machine X3 and A8 +) POW mining.
however, some Shanzhai coins are purely tools for developers and users to earn money. There are two main ways to make money by using virtual coins: one is mining. For example, if you want to obtain bitcoin, you must use a professional ASIC miner to mine (Avalon miner), and the bitcoin obtained from mining can be traded on the trading platform; The other is trading on the trading platform and making money by using the price difference
Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension
after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card
CPU is not very important. But not lower than i5< br />
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it
mining is definitely the first professional mining machine. Many new children's shoes will choose to mine with graphics card. However, mining with graphics card is just like doing a professional job with "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.
RMB will continue to depreciate. The current price of US dollar against RMB is 6.7572. In the future, it will be 6.9000 and 7.1550, or even 7.42 or higher. It is only a matter of time. One US dollar will depreciate by 2-40 cents, or even more, and 10000 US dollars will depreciate by 20000-40000 yuan, It's equivalent to your current 67500 yuan. In the future, it will be equivalent to your current 47500-27500 yuan. As long as you invest in RMB, it will be the result. It's not like this if you change it into US dollars. Changing it into US dollars will only make the RMB in your hands appreciate! Now 67500 is converted into 10000 US dollars, and after a period of time, it will be 87500-107500 RMB yuan when it is taken out and then converted into RMB. This is the fact
now there is a better project. It is the first to make money by changing your RMB into US dollars; Second, we should make our robust EA, with an average monthly return of about 5% and a maximum principal risk of 10%. Of course, there are other strategies for EA. We should make it robust according to the risk preference of investors. After all, most investors are risk averse. At present, the operation of robust EA has been nearly 10 months, and the international tripartite financial website has been publicized for more than 3 months. Hundreds of customers are using our robust EA proct. The average monthly income is about 5%, and the maximum principal withdrawal is about 3%, which is very robust
the current stock market is not optimistic, and there is not enough action in the market, even before the bull market. Even if you can get 30% of the annual stock return, the RMB will continue to depreciate, and when you pay out, it will be far less than 30% of the return; I suggest that we can choose to invest in foreign exchange at present. We can find a reliable and qualified foreign exchange platform to deposit our money. Our platform is very good. Capital security, trading environment, back office management system and our service are all great. Even if we don't do our steady EA, we only deposit it in US dollars and withdraw it after a period of time, your RMB will appreciate! Compared with stock speculation, bank financing, various types of RMB financial procts, value preservation and appreciation much more
if RMB is converted into US dollars and deposited in the bank, each person will only have the maximum amount of US $50000 per year, and the payment proceres are quite troublesome.
the requirement of mining grade is to use a pick to knock a stone,
have a little experience in knocking a stone,
have no experience other than that,
but the advantage of bomb is to save time and physical strength,
so don't use a bomb when you rush the grade,
you can use it to brush the mine hole
The price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, the high configuration bitcoin "mining machine" increased from 10000 yuan to 300000 yuan, but its performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013. Mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, the computing power after "grouping" can surpass the single graphics card of most users. And this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Taking into account the hardware price and other costs, there is a considerable expenditure in mining< br />
