1. Bitcoin mining 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
one of the ways to get bitcoin is that users download software from personal computers and then run specific algorithms to communicate with remote servers
simply put, it is a box like a computer host. Plug in the Internet cable and power supply, and configure the account information
to automatically "mine" - generate bitcoin
2. The popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole
point coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
the price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan
3. From 2011 to 2013, high configuration bitcoin & quot; Mining machine & quot; From 10000 yuan to 300000 yuan, but the performance is better than before
a lot
4. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed
degrees
The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the full network computing power and difficulty of 2013power consumption of bitcoin mining machine:
according to digiconomist's bitcoin energy consumption index, as of Monday (November 20), the current global annual power consumption generated by "mining" for
bitcoin is expected to be 29.05twh. TWH is one kilowatt hour, equivalent to one billion
power consumption per 100 S4 bitcoin mining machines is 900W per hour, and power consumption per S4 bitcoin mining machine is 90W per hour
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
extended data
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
Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension
after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card
CPU is not very important. But not lower than i5< br />
my view of bitcoin is that it is a very risky investment. Some scholars have pointed out that bitcoin is halved every four years, which was originally designed by Nakamoto. Moreover, Nakamoto has also designed the total amount of bitcoin, which has prevented inflation to a certain extent. However, it is precisely because the bitcoin reward of blockchain is halved every four years, so in 2016, after the price of bitcoin plummeted, it quickly recovered and reached its peak. Therefore, it can be said that this design of Nakamoto Tsung actually ensured that the value of bitcoin would not decline too much to a certain extent. Bitcoin has entered a crazy state since 2017. The price of a bitcoin once rose to more than US $20000, which caused many speculators to rush in. Bitcoin, based on blockchain technology, entered an oscillation period of decline at the end of 17. It once dropped to about US $5000 and rose to more than US $10000 after the Spring Festival. It can be seen that every time the price of bitcoin falls, there will always be a lot of money coming in to boost the price rise, and there will always be the shadow of operators behind
why is bitcoin so popular recently! Let's talk about my views:
first, there are a lot of myths about sudden wealth.
for example, the founder of reborn coin has become the richest man in the blockchain. Some people are worth hundreds of millions in a short time relying on bitcoin. In addition, people like baoerye are telling stories everywhere, from beef sellers to Rolls Royce mirage who can buy limited edition, Many people yearn for it
{rrrrrrr}
4. The title of bitcoin blockchain
the blockchain technology behind bitcoin claims to replace all centralized organizations, which is obviously a utopian plot, but utopia is often beautiful, although it can not be realized, but everyone goes for it
I think that bitcoin is actually a data logic in the guise of blockchain, and its existence foundation is very fragile. Once there is a problem, it will lose everything. Therefore, the risk of the currency market is too great, so we must be cautious if we want to enter the currency market
