MGK power mining 50 can make money

2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.

3. I have used sesame computing power for nearly half a year. Since I participated in the crowdfunding of mining machinery in August last year, I have recovered my capital. Mining machinery is still digging, and I can make money!

4. Cheat, pay money into the member first, dig the mine can't trade, can't withdraw cash, I am cheated

5. Graphics card efficiency is so low, can sell out of stock, mining is now hot, hard to find a machine ah
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.

6. Now it's not very profitable. In 12 years, the price of bitcoin was about 1000 +. With personal PC, we could dig more than one coin a week. The current currency price is about 20000 yuan
Development:
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. West Virginia Democratic Senator Joe; On February 26, 2014, Joe Manchin issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China.

7. Bitcoin's computing power continues to rise today
according to bitinfocharts, the computing power of bitcoin network continues to rise today. Although bitcoin was unable to break through the $10000 price after its fall in February, the growing computing power in the past few months means that miners are increasingly interested in mining
in addition, whether mining makes money or not is related to computing power. If computing power is strong, the income will be high. Indivial mining can't make money now. It needs a certain scale of mining pool. If you encounter a good computing power platform, you can pay attention to it.

8.

The building owner's circuit diagram is drawn by himself according to the appearance on the board (the main board is 4 floors and above, so it's impossible to draw the Kanban diagram)??? Or where

no matter how it comes, the picture is wrong. Vin is the input of 5.2-28v, SW1 and SW2 are the output of 5v-36v

your circuit drawing is too simple. It's impossible to draw a picture by kanban. The computer motherboard is made of several layers of PCBs. Your problem is still looking for power supply problems, component problems, chip problems, such a sequence of troubleshooting

if you look at this application circuit, it may be helpful for you

9. How to say this? Now the mining machine is really not fragrant. Although only a few people know it, it's really unnecessary
