1. 1、 bitcoin is an experimental currency, and the consensus of core members is that bitcoin is only a virtual experimental currency. Its existence value is to prove whether money must have thing value or only need a currency symbol. If it survives, and can always be used as a trading chip, then the proof of money does not need physical value, as long as a reasonable currency symbol. If it can not survive, then the proof of money must have a certain physical value. 2、 Bitcoin is "mined" by calculating the results of mathematical problems. I think you can pay for bitcoin to get an answer to a math problem. You know, computing resources are valuable, and many people don't realize it.

3. Mining is definitely the first professional mining machine. Many new children's shoes will choose to use the graphics card to mine, but the graphics card mining is just like doing a professional job with the "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.

4. Butterfly laboratory in the United States is from the United States. He prefers to evade tickets. It seems that he has been prosecuted recently. As we all know, the overall performance of the garden miner is not good, and the energy consumption of the ant miner is relatively small, but the chip is made by 55nm process technology. According to the development of current technology, it will be eliminated soon. Cat roaster used to be brilliant for a time, but with the technological progress of other mining machine manufacturers, it graally went down. In contrast, Avalon has been at the forefront of innovation. Avalon delivered the world's first ASIC miner. Avalon1 once made a noise from 8000 to 300000. Avalon's second-generation chips contributed about one third of the computing power of the whole network in January. At present, Avalon has delivered the first batch of orders for the third generation chips with 40nm process technology.

5. Foreign countries need to do in the inspection, and then apply for import license on the line, looking forward to the joint fine

6. The mining machine of bitcoin is actually the computer equipment in our life. However, e to the special conditions of bitcoin proction, most of them are equipped with professional mining chips and work in the way of burning video card. Therefore, the mining machine is required to have good ventilation and heat dissipation and sufficient power resources.

7. Yes, the bitcoin mining machine is a large computer.

8. No, the first one is the same as drugs can extract drugs. The second one is that although mining is meaningless, it is profitable for indivials to replace electricity bills. It's personal profits, but also pay the electricity bill. There is no violation of the law before there is no clear legal restriction

9. Generally, one version of office is installed in your computer, but it is not activated, and it is not unloaded completely. Then another version of office is installed, and the latter is activated. I also encounter this problem. At present, I have solved it as follows:
1 Run the following command to check the current office procts in the system and their activation status:
in windows, open the command prompt with administrator privileges
then type the following command:
cscript.exe & quot;% ProgramFiles%\ Microsoft Office\ Office16\& quot; Ospp.vbs/dstatus
note: modify the above path according to your office installation directory. If your office is a 32-bit version and is installed in a 64 bit operating system, please run the following command:
cscript.exe & quot;% ProgramFiles(x86)%\ Microsoft Office\ Office16\& quot; Ospp.vbs/dstatus

after running, it will generally display the activation status of two versions, such as a batch authorization version and an office 365 version
2. Enter the corresponding directory
CD C: &# 92; Program Files\ Microsoft Office\ Office 16 "installing 64 bit office on 32 / 64 bit operating system"
or
CD C: & # 92; Program Files (x86)\ Microsoft Office\ Office16 "installing 32-bit office on 64 bit operating system"
3. Delete the version that has not been activated before, such as office 365. Generally, win10 will pre install this version, and then do not give the activation code, which leads us to uninstall it and then re install other versions. After activation, office always thinks that we have not activated 365, so it prompts that it has not been activated
step1:
cscript ospp.vbs/dstatus
"display the installed key, and the 5 digits displayed at the back of the screen: xxxxx" are as follows:
"last 5 characters of installed proct key: xxxxx"
Step2 (find out which is not the last 5 digits of the activation code you entered and delete it):
cscript ospp.vbs/ unpkey:XXXXX "Enter the five digits displayed in the previous step, Delete key successfully
Step3 (if you have entered the activation code before, you do not need this step):
cscript ospp.vbs/ inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX "Input new key, replace key successfully {if key is valid}"
If only one key has been installed, then office has returned to the original activation state. If not, repeat.
