Did MGK mine collapse
mining refers to the use of bitcoin mining machine to obtain bitcoin, that is, the computer used to earn bitcoin. If you can get bitcoin, you can make money this kind of computer generally has professional mining chips and works by installing a large number of graphics cards, which consumes a lot of power. The computer downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server
precautions:
1. It's better to use DIY mining machine, from purchasing accessories to assembly, and then to mining software, to learn, focus, practice and graally understand the blockchain
Mining is actually a fixed investment process: regardless of the currency price, a certain amount of positions will be increased every day3. The bitcoin wallet used to store bitcoin uses military level encryption, which makes it impossible for hackers to steal easily. Bitcoin wallet also allows users to set two passwords, a public account password and a private password. The user of public account password is to let the user receive bitcoin. If users want to withdraw or transfer bitcoin from their accounts, they need to use a private password

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
In the 1960s, some major coal procing countries in the world adopted reciprocating "Z" mining, advancing and retreating gob side entry retaining methods to achieve no coal pillar mining in order to rece roadway excavation, increase coal resource recovery rate, increase proction continuity and improve economic benefits of mines. A lot of research has been done on the mine pressure behavior, applicable conditions, reasonable support forms and new support materials of gob side entry retaining. The former Soviet Union, Germany, Britain, Poland and other countries have done more in this regard. These developed countries attach great importance to the exploitation of this kind of disposable energy
in China, from thin coal seam to thick coal seam, from gently inclined coal seam to steeply inclined coal seam, there have been successful experiences of gob side entry retaining. However, there are still some deficiencies in the research and application of gob side entry retaining technology, which makes some mines fail to achieve the expected effect in the application of gob side entry retaining technology, and limits the wider promotion of gob side entry retaining technology in China
after decades of development, some mining areas in China have made gratifying achievements in gob side entry retaining. Some mines have achieved very objective economic benefits
gob side entry retaining technology is in a golden age of rapid development
