Bench mining

1. To understand the problem of home computer mining, we must first explain the mining clearly. As like as two peas came out, they shared a identical record book, so they need a person with a right word to decide the record. Who will record it? Through a topic to decide whose computer is right first, then it has the right to record all the data of this block. This is the popular explanation of mining. And reward the bookkeeper to get an extra sum of money, which is the reward for mining. Reward the person who has contributed enough computing power to solve the problem, which is also the reason why we go mining. Money is money, in order to make money. In the beginning, bitcoin mining was just about CPU. Then, for more money, technicians developed faster and faster accounting methods for graphics cards, FPGA and ASIC chips. Please note here that bitcoin is only the bookkeeping method. Bitcoin is the sha256 algorithm, which is only applicable to this kind of algorithm and can only be used for mining. Later, more algorithms appeared, such as ethash, kawpow, cryptonight, zhash, x16r, randomx, etc. Pay attention to the concepts, algorithms (the above pile) and devices (CPU, graphics card, FPGA, ASIC). They complement each other. A currency may have multiple algorithms or a single algorithm for accounting. The same device can also run different algorithms to get different rewards. The only difference is the efficiency of accounting and the speed of making money. So bitcoin can be g with CPU, graphics card, FPGA and ASIC, but ASIC has the highest efficiency and cost performance. Let's go back to the topic, what can a home computer dig? Home computer = CPU + graphics card. The more suitable CPU is the monero under the randomx algorithm. For graphics card, it is suitable for the automatic selection of nicecash. Now I should talk about the specific mining tutorial to complete the answer, but I recommend a simpler and more convenient method, even without knowing all of the above.

2. Just download a gpu360 miner
common computer mining methods:
1. Download and install gpu360 miner
2. The software will be set to boot, it is recommended to boot. Because it has a very human function, when you don't use the computer, it will automatically mine, when you use it, it will stop instantly, it will not affect the normal work and use
3. After the software is started, change it to your own mobile phone number. After the software starts, there are three setting options:
4. The first time you start mining, you will test the equipment, and it will test your best mining scheme. It usually takes about ten minutes
5. After testing, it will automatically enter the mining state
6. Click stop and close to minimize to the tray, so that when you don't use the computer, it will automatically open to make money
right click the icon to shut down the software completely
7. Bitcoin earned can be exchanged directly in online stores.

web link post bar example:

we will calculate the graphics card to dig bitcoin earnings

assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s

HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days

OK, all the parameters are ready, calculation
in calculation...

eh, how come it's a negative number

because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low


suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950

Computer Mining: when users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins. In short, it's about looking for bitcoin

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

extended data:

the corresponding laws and regulations of computer mining in China:

in China, the regulations on the administration of RMB prohibit the proction and sale of token tickets. Because there is no clear judicial interpretation of the definition of token ticket, if bitcoin is included in the "token ticket", the legal prospect of bitcoin in China will face uncertainty

the notice of the Ministry of culture and the Ministry of Commerce on strengthening the management of virtual currency of online games (Wen Shi Fa [2009] No. 20) on June 4, 2009 stated that the application scope of virtual currency of online games was defined for the first time, and the distinction between the current virtual currency of online games and the virtual props in the game was made; At the same time, the notice said that the "notice" stipulates that enterprises engaged in related services must be approved before they can operate

in China, some Taobao stores also began to accept the use of bitcoin, and the number of businesses will graally increase

in October 2013, the first bitcoin quarterly, one bit, was released

on October 15, 2013, the network accelerator service of the network announced its support for bitcoin

on October 26, 2013, btcmini reported that GBL was hacked

on October 31, 2013, Lei Teng, a famous Internet lawyer, proposed the event of "filing a case to investigate the closure of GBL bitcoin trading platform as soon as possible", analyzed the "value function" and "use function" of bitcoin, and bitcoin should be governed by relevant laws

6. Young man, be realistic. It's unrealistic to mine. If you take home computers to mine, don't use machines?!

7.

Notebook can be used for mining

most virtual currencies use a mechanism called proof of work (POW) to distribute rewards, and the core process is hash operation. So ordinary computers can also mine

ordinary computers can be used to dig bitcoin, because mining itself is just computing. Professional mining machines dig well, dig fast and earn a lot. Ordinary home computers dig slowly and earn less

for example, there are mature professional mining machines for mining bitcoin and lightcoin

extended data

because of adhering to the principle of server construction, the whole mining machine is miniaturized, and the specially designed mining chip is adopted, which is born for the optimization of bitcoin / lightcoin algorithm, with a single computing power of th / s level. However, in order to ensure stable operation, the chip will be covered with aluminum cooling fins, which will be blown through by the front and rear violent fans, but the noise is high, so it is usually placed in a factory

in addition, this kind of professional miner is expensive and uses customized chips. If you don't mine, you can't use it again. In short, you can't do anything except mine

however, if an ordinary computer is a little more professional in mining, it is necessary to select a motherboard specially designed for mining, for example, a motherboard with 10 PCI X1 interfaces, a PCI to USB expansion board and other hardware, and modify the graphics card BIOS at the same time, so as to achieve more powerful computing power and indirectly increase revenue
