Bitcoin mining interface
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
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
according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens' investment and transaction of virtual currency are not protected by law

fortunately, it is such a leaky system that it will probably never grow to a point where it will have adverse effects or impacts on the world economy
however, I feel it necessary to point out the problem
bitcoin is more like a data transmission system than a cash trading system. Well, the problem is that it doesn't make a deal by offering a digital cash deal in dollars, but by importing a whole new currency. So here we will ask, is this really desirable
one of the fatal problems: the distribution of initial wealth
when the Federal Reserve prints money, it will not issue millions of dollars of checks randomly to thousands of Americans. The work it does is: 1. Buy some other assets (usually US Treasury bonds) in the free market to inject more cash into the system than before; Or, 2. Lend money to the bank, the bank lends money to others, and finally spends the money
the important thing is that these people don't get money for free. They either sell their assets for cash, or borrow money to spend it and eventually pay it back (also paying interest)
the bitcoin system does not have a central bank to issue currency. It has an "algorithm" that allows bitcoin to be "mined" through a rather puzzling mechanism. Basically, it's randomly assigned to people who are early in the tasting season. It's a very good system for early entrants (free money!). It's a ridiculous system for real money, not to mention the obvious lack of expansibility (what happens if everyone mines all day long?) In order to solve this problem, the supply of bitcoin is algorithmically limited, which once again brings benefits to early entrants, but this leads to the second problem:
the second fatal problem: endogenous deflation
economics course time! Deflation results from the appreciation of currency relative to other commodities (such as the decrease of commodity prices). More directly, deflation occurs when people expect the currency to appreciate relative to other commodities, and the price trend continues to decline
question: if money is expected to appreciate, why do you spend it? Answer: Generally speaking, you don't spend money
the supply of bitcoin is set to slow down at a known rate. It eventually reached about 21 million. As shown in the picture
we can see the rate - well, I agree that if it is foreseeable inflation, it may not be desirable from an economic point of view, but it is reasonable. However, if it is to slow down the issuance, if you design a currency to subvert the world order, what you would like to see is this graph:
then what if there is at least a constant growth rate? You may be willing to do that, because that's the only way to adapt to more people using it
but bitcoin is not designed to be a practical currency, it is designed to make early entrants rich. Once again, it's a hoax
for a quick thinking experiment, we assume that more people use bitcoin compared with the growth of demand for bitcoin. In this way, we can expect the dollar price of bitcoin to rise rapidly. Now suppose I have a bitcoin, I also have a dollar bill, I am willing to buy a bottle of Pepsi Cola, which payment method will I use? Obviously, the devalued dollar should be spent more than the rapidly appreciating bitcoin
in the best case, the limitation of bitcoin supply will cause severe deflation, squeeze most of the business activities of bitcoin pricing, and connive at speculation in the trading market. If you are not willing to use it and others are not willing to use it, the so-called benefits of transparency and low transaction costs will not bring you any benefits< The third fatal problem is the lack of convertibility. People have a misunderstanding about the so-called intrinsic value of money. In fact, there is no so-called intrinsic value of money. The nominal value of money is limited to the other money they can trade for. One dollar is equivalent to a certain amount of euro, one euro is equivalent to a certain amount of yen, and one yen is equivalent to a certain amount of dollar. One dollar can be stored in the bank, change a certificate of deposit, and then the certificate of deposit can be changed into one dollar. It can be turned into a commercial or personal check and then into cash or deposit. When you travel, it can be changed into a traveler's check in yen or euro. If you have to pay for sandwiches, the sandwich shop also charges because the money can be converted into something else. It's a wonderful circular balance.
