When is bitcoin miner cheap
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.
this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad 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 some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned

mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
Babbitt has a bitcoin mining income analysis article, which has a figure for reference. According to its calculation, it's 132 days
the official said that the power consumption is 1350W, which is calculated according to the maximum 1500W per hour
according to our third-class household electricity consumption, the daily electricity cost is about 30
the daily profit is about 30. Currently, the new 13.5T machine's official website is 1.5W
to sum up, it takes about 500 days to have free electricity It will be faster next time
literally, bitcoin comes first, then blockchain. Bitcoin started in 2009 and blockchain started in early 2014
in essence, blockchain technology is a collection of technologies, mainly composed of distributed account book data
bitcoin is an application. In order to achieve some of the purposes of bitcoin, some technologies are used, because bitcoin is more and more valued by the market (that is, the price is getting higher and higher). These underlying technologies are later refined and called blockchain separately
then, their relationship is similar to that between internal combustion engine and automobile
in order to run, cars use internal combustion engine technology
the internal combustion engine technology is also widely used in trains, small power stations, agricultural machinery, engineering machinery, merchant ships, conventional submarines and small airplanes because of the wide application of automobiles. The number of internal combustion engines in the world ranks first among the power machinery of human beings
if you understand the relationship between blockchain and bitcoin in this way, is blockchain technology important
it's important, but more important is the structure of all kinds of human data and the decentralized future realized by this technology.
