Virtual currency mining machine concept stock
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. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
in view of the possible risks of virtual currency, many international organizations and central banks have responded publicly to the supervision of virtual currency system. These responses can be roughly divided into four categories: warning and risk warning, supervision and registration permission, legislative norms, and explicit prohibition
(1) warning and risk warning
some central banks and regulators have issued risk warnings against the special currency and virtual currency system. The federal financial regulatory authority of Germany, the Bank of France, the central banks of the Netherlands and Belgium have issued public warnings against the possible money laundering and terrorist financing caused by the use of bitcoin. In the report released at the end of 2013, the European Banking authority (EBA) warned consumers of many risks of virtual currency, such as exchange loss, e-wallet theft, unprotected payment, price fluctuation and so on. Although Spain did not have a similar risk warning, it issued a timely information announcement related to virtual currency
(2) supervision and registration license
generally speaking, international organizations believe that the supervision of virtual currency should find a balance between risk prevention and innovation promotion. Since 2012, Sweden has required transactions related to virtual currency to be registered with financial regulators. Other countries pay attention to qualification supervision, so as to make it indirectly meet the requirements of prudential supervision. In other countries, the regulation mainly focuses on the business model of virtual currency transaction. The financial prudential regulatory authority of France regards the provision of bitcoin circulation and trading services and the act of earning funds in the process as a payment service and requires the authorization of the government. In addition, some countries focus on the intermediary institutions related to virtual currency. The German federal financial regulatory agency and Danish regulators believe that the provision of intermediary services for virtual currency needs to be authorized< (3) legislative norms
at present, some countries have proposed legislation to regulate virtual currency transactions. Canada plans to legislate to allow the government to supervise the transaction of bitcoin, and to include the transaction of more than US $10000 into the scope of suspicious supervision. The United States hopes to adjust the relevant legal structure should be compared with the development of the special currency. In order to make the Bank Secrecy Act (BSA) applicable in the context of network, the financial crime enforcement network (FinCEN) of the U.S. Department of the Treasury issued the explanatory guidance on the behavior and subject definition of private generation, holding, distribution, trading, acceptance and transmission of virtual currency in 2013. The European central bank stressed that it should strengthen international cooperation under the existing legal framework, and regulate virtual currency from the European and global level under the existing legal framework. More countries believe that bitcoin is not a currency in circulation, has no legal status, and does not meet the definition of financial instruments, such as Finland, Sweden, Malaysia and Indonesia
(4) it is forbidden
in some countries, bitcoin related transactions are prohibited. In December 2013, the people's Bank of China banned financial institutions from trading in bitcoin, which was subsequently extended to payment service providers. The central banks of Thailand and Indonesia share the same attitude. The circulation of anonymous internet currency (including bitcoin) is prohibited by the Russian judicial inspection department as a substitute for currency. The Central Bank of Russia has earlier included the provision of bitcoin services in the scope of suspicious transaction monitoring. The U.S. Securities and Exchange Commission (SEC) has banned the issue of unregistered shares in exchange for bitcoin, and unregistered online securities trading activities in virtual currency.
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.
