Xmrstak mining efficiency

1.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

2. No one uses 1080 or more graphics cards to mine

because the cost performance is too low, the computing power is not improved much, and the price is too expensive.

April 9, 2020 update reply, the problem has been solved, in the bottom of the answer

April 8, 2020:

although it has been a long time, but still answer, I recently encountered a similar problem, you may hit the Monroe coin mining Trojan horse, there is a cmdc.exe in the deep directory of Disk C, every time the mouse stops for a period of time, it will start to execute, The mouse disappears from the resource manager with the help of Microsoft's Process Explorer tool. We haven't found a solution yet. After deleting it, the mouse will be still for a while and the related files will be created again. The config file at the bottom indicates that it is generated by XmR stak, which can be found in network search

on April 9, 2020, the problem has been solved. It is estimated that it is a novice or novice of mining Trojan horse. After replying to this problem on April 8, the following actions have been continued:

1. according to the file creation time of cmdc.exe, if you use the directory where CMDC is located to open it directly with resource manager, you can't see any files, We can only use the advanced search function of tools to find the files created on the same day and two days before. We find that there is a cmdc.zip in the superior directory of cmdc.exe, in which the files related to cmdc.exe are deleted

2. according to the file creation time of cmdc.exe, find all the programs installed within 18 days and 2 days. During this period, the program installed is Utorrent, and the program is unloaded. Continue to use the search everything tool to search all the files by the keyword Utorrent, and delete them
   
   after the above, the computer did not operate for 20 minutes, and there was no cmdc.exe again, and the computer resource curve was stable, and there was no temperature surge and fan crazy running

< / OL >

later, I searched for Monroe coins on station B, and there was a mining tutorial..... After a few eyes, this thing is to use the CPU or GPU of the computer for mining, generally the CPU. What I met was GPU, and there would be the user account of Monroe coins in the relevant configuration file (I only blame that my file was deleted too fast to find)

in a word, the lesson is that if you don't use the cracking tools, you need to be prepared for psychological and property losses. When the temperature of the computer soars abnormally, you should pay special attention to this situation, and you may have been caught,
P.S. at the beginning, I thought that there was something wrong with the heat dissipation, cleaned the fan, and re coated with silicone grease, but it didn't work

4. As long as it is a virus, it can be deleted.
this virus is a kind of stubborn virus. It needs to be killed in a safe mode.
the choice of antivirus software is also very important. You have to choose a special killing tool for this virus. You can use the computer housekeeper to kill the virus.

5. XMR-Stak is a universal Stratum pool miner. This is the CPU-mining version; there is also an AMD GPU version and an NVIDA GPU version
