What's bitcoin for investment
the function of bitcoin, or the dream of its followers, is to realize the gold standard monetary system (in fact, there is no upper limit for gold, but bitcoin has a total limit), and create a currency with a slowly increasing supply and a total limit. Thanks to the distributed database, the transfer of bitcoin does not need to go through a third party and is irreversible. This is a very important feature, and this is its potential
with the graal rection of output, the value will graally increase in the long run. There are more and more audiences
e to the limited level, my explanation may be different, but this is generally the case.
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.
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
1 China bitcoin trading platform, after entering the website, register
2, after successful registration, you can buy and sell bitcoin. Under the trading function, you can buy and sell bitcoin, manage the entrustment and query the trading operation. Under the account management, you can transfer in and out bitcoin, Transfer in and transfer out of RMB
3 RMB recharge and withdrawal support a variety of ways, and the handling charge is relatively high, and the limits and handling charges of various ways are different
4 the transfer in and transfer out of bitcoin refers to the transfer of bitcoin between the trading platform and the bitcoin wallet. The bitcoin wallet needs to be downloaded from the bitcoin official website, and the data needs to be synchronized after downloading and installing, The current packet size is about 8.5g, which takes a long time to synchronize. For friends with small investment, you can skip it. After the installation of bitcoin wallet, there will be a default acceptance address, which can be pasted when the trading platform withdraws bitcoin, while recharging is a reverse operation. The trading platform will give you an address
-
the transaction of bitcoin needs to pay a certain handling fee. The transaction handling fee of bitcoin China is 0.3%, which is equivalent to the upper limit of the Commission of stock transaction. In the trading platform, there is the latest trading data, also can refer to btc123, the market data is more intuitive. Bitcoin trading is different from securities trading. There is no limit to the rise and fall of bitcoin, and it trades 24 hours a day. The whole market plate is small, and it is easy to be controlled by the makers, and it may also be attacked by hackers. Therefore, the risk is huge. It is recommended to invest cautiously. Novices had better understand the relevant concepts first If you don't want to put the website, please search by yourself]

Although many investors know nothing about bitcoin mining, they still can't resist the temptation of bitcoin price and plan to invest in the mining army. So if you also want to mine, I believe you will have a question in your heart: "what is a bitcoin miner? What is the principle of bitcoin mining machine? " To solve this problem, let's remember some popular science today
origin of bitcoin
to fully understand the origin of bitcoin, we have to mention the existing financial system
bitcoin mining machine specially used for mining. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world
with the orderly implementation of cashless society, banknotes will inevitably disappear in the long river of history with the passage of time. The future digital currency is believed to be similar to bitcoin, but it is by no means a limited supply. But when the human ability to proce wealth can be completely matched by the computing power of the computer, the issuing speed of e-money is directly proportional to or slightly exceeds the computing speed of the computer to create moderate inflation. In the future, while mining, it is also creating value rather than wasting electricity. In the end, the small changes in proctivity of digital currency match the difficulty of computing power, which may be the final form of human currency
When you heard that many people who bought bitcoin got rich overnight, Japan also legislated to accept bitcoin, and then the major businesses supported bitcoin payment... You also have grass in your heart. Although I don't know what this coin is, it seems to make a lot of money. Do you want to buy it for two yuan
With a wave of his hand, Mr. Nakamoto, you guys need not worry. In order to make money... Oh no, in order to save the economic crisis, I have already considered this small matter carefully. In order to ensure the authenticity and quantity of each coin, each of us has a small notebook. On this magical notebook, you can see the birth of each coin, and everyone is a witness. At the same time, for the sake of safety, our notebook also has a very cool function, which is to have an invisible lock. You can only see it, but you can't change it. This kind of bitcoin has authenticity and authorityat the same time, you can rest assured that bitcoin will not be used in vain. I have found many "bricks" of mainstream economics, analyzed bitcoin and predicted that it will become the mainstream currency in the future. Now you can dig (Jian) currency without spending a cent, and you can wait for the currency to appreciate. Isn't it super good
this boasting, we listen to the bious, some people go to dig (Jian) money, some keep watching. At this time, Nakamoto took action. In 2014, he secretly united with American e-commerce giants such as eBay, airbnb and Uber, which began to accept bitcoin payment. Since then, the bitcoin market has really begun. Many people know that there is money coming in vain, and they also begin to join the ranks of coin digging. However, the number of people is still small, and there are not many coins g up
until 2017, when the blackmail virus incident occurred and the whole world suffered from large-scale network virus attacks, the poisoning unit had only two choices, either waiting for the computer to GG and the data disappeared, or paying about RMB 2069 bitcoin to unlock
this made bitcoin instantly become global famous. At the same time, all units had no choice but to buy coins. At this time, the brothers who had been digging for (Jian) coins for five or six years had a collective climax. There were so many coins. You want to buy them, right. In this way, the value of pure virtual bitcoin without real value soared to $2151 / piece
since then, as you have heard, XXX has accumulated more than n bitcoins, which have soared ten thousand times and become rich overnight
up to now, the creator of bitcoin, Nakamoto Tsung, has become a fan of identity, but bitcoin is still not accepted by most countries, including China. At present, bitcoin's high trading volume is also an illusion. Most of them are bad speculators. Through high-frequency trading, they create an illusion to attract investors' attention. This practice is equivalent to Taobao's swiping orders
for you who want to invest, you still need to clarify some things
1. Bitcoin is not restricted by law, and of course it is not protected. Once your trading platform is attacked by hackers, your currency will be lost, there will be no place to find it, and there will be no place to reason Many people go to the rooftop)
2. The fluctuation is very great. You only see a ten thousand fold increase, but not a half drop overnight
3, bitcoin has no issuer. In today's financial world, the currency of no issuer is worthless, and the bubble economy may collapse at any time. p>
the last word of advice: don't touch bitcoin as a rookie, or the old bird will speculate and run when they earn money, otherwise they will be sad
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.
the previous answer is to invest in bitcoin. The landlord asked to dig bitcoin. You didn't answer the question. Oh, you need machines to dig for bitcoin. The computing power of home PC is too low. According to the difficulty of more than 900 million, the computing power of home PC is generally between 100 m and 600 m. if you dig for bitcoin, you can't earn one tenth of the electricity bill, so you need mining machine, At present, the monthly income of 200g mining machine is about 7500, and the price of the machine is about 20000. But now the price tends to be stable, so it will not go up like it did a while ago. It is estimated that the price will be stable at about 3500 in the next few months. So the answer is to make money, it depends on what kind of machine you use to dig.
