Bitcoin Mining Group
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. 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 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
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
as a miner, I used graphics card very early and then butterfly machine. At present, I use Avalon's 220 miner and just received a new 180 ant miner. To tell you the truth, mining is not as simple as you think. Here I will list some practical difficulties you need to face in mining. If you find that some of these items can't be solved and overcome for the time being, don't rush to buy a miner, because from the moment you buy, if you can't mine, Then you will face a real loss
first, list the problems to face
1, be able to accept the noise - the noise of the mining machine is very loud, which is equivalent to that you put the air conditioner outside the room
1-1, strong hands-on ability - the noise can be controlled to a certain extent by adding water cooling, but it needs to be done by yourself. The installation process of water cooling is not as simple as the online tutorial. It needs to be extremely careful. The capacitor on the logic board is easy to touch, and it must be successful at one time. Once the refrigerant is added, the machine will have problems again, It would be disastrous to dismantle the water cooling system
1-2, conditional repair of the chip capacitor - in the process of water cooling installation, the capacitor is easy to fall off, these chip capacitors are very difficult to weld
2, you can set up the network - you can't just plug in the Internet cable! Need to understand the routing, know how to change the IP of the router, mining IP is fixed, according to mining IP to do settings
2-1, you can get a fixed IP address - if you are mining in a company, you can't set up a route, so you must have the condition to get a fixed IP, and then set up your own network through this IP
3. The environment of continuous power supply and continuous network - mining is a 24-hour business. Don't take it for granted that a meeting is OK in one day. Many companies will cut off power at midnight. This must be made clear
3-1. In low temperature environment, in addition to 24-hour continuous power supply, there should also be a relatively cold environment. In actual mining, we can clearly feel the importance of temperature for mining<
let's assume two scenarios,
in the company:
if your working environment is very quiet, it is not suitable, even if water cooling is installed. If you are a senior blue collar, in the workshop, do you have the conditions to set up the network and get a fixed IP? If you can't, give up
at home:
can you stand noise? Can tolerate to a certain extent
is it possible to install water cooling? It can be installed conditionally
is it possible to set up a network? There are also conditions to set up the network
is it warm in that room? Yes, but you can open windows on the second bedroom or balcony
is it possible to pull the wire and the wiring board in the balcony? No problem
congratulations, you can buy a miner to dig it up, but if one of them doesn't work, you need to think carefully before making a decision
the above-mentioned points should not be taken as unimportant or major problems. For example, it is necessary to have the conditions to install water cooling, for example, in a lower temperature environment, for example, to have a fixed IP
when the miner starts to operate and makes a rumbling sound, if you are in the company, you have to turn it off awkwardly. If you are at home, you need to figure out how to explain to your family or girlfriend that the noise will exist for 24 hours, and hope they don't mind
if your home is warm, your miner will never be able to achieve the highest computing power it can. You must accept it calmly, don't be depressed, it's useless to find the seller. Unless you open the window to let in the cold air, you will find that you and the miner are so out of place. That's why laomaozi is very fond of mining< Make complaints about mobile phone, br / > and if you work hard to move the mine to the company, you may think that the electricity charge is in the whole province. You can't get the mine to connect. Then you can only move the mine to home or sell it as a second-hand machine...
these words are typed word by word by me. I hope it can help you. You must find out whether you are qualified to do this at present. As for how to dig, it's a very simple thing: buy a miner, register an account on a mining website, Download a multibit to store the bitcoin you get, and link the miner to the network for power on, Set up the network, give it the fixed IP specified on the chassis, use the computer to access the IP, make some simple settings, and then wait for the receipt
what else can I ask you
As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal
bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
extended data
the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

Bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security
The global epidemic has led to the regression of the real economy, while the virtual currency economy has entered a new stage of development< as the world's first cryptocurrency & mdash& mdash; Bitcoin has risen by more than 250%, from the lowest $3000 to today's $58000, which can be described as a rising tide. With the continuous improvement of virtual currency income, bitcoin's mining facilities also follow; Red & quot; I got up
as the future monetary system, bitcoin is decentralized. It's not a belief of blockchain mechanism. Due to the data leakage and privacy security problems caused by the current social centralization, it's difficult to guarantee. So many followers of bitcoin think that bitcoin is a consensus, which brings convenience to their life. But this belief has brought the cost of global environmental pollution, which is not optimistic by people
