Bitcoin 1 PC skill
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
Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. Bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment
but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over
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
in fact, you don't need to understand some principles of bitcoin, because it's very difficult to understand. Even professionals may not understand all of them. As long as you can use it
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system
you can get it through bitcoin mining or direct purchase on the trading platform
bitcoin mining is the process of using your hardware to calculate mathematical problems, confirm transactions, and ensure the whole network system. As a reward, you can get a certain bitcoin reward. At present, mining is competing for energy consumption and electricity price, and mining income is close to cost price. Avalon's fourth generation chips have certain advantages in energy consumption
you can buy bitcoin directly by recharging the legal currency to the trading platform, and the third-party guaranteed transaction.
As we approach the end of the year, when we plan to sprint for the goal of the end of the year, earn more bonus and prepare to release ourselves in the Spring Festival, don't forget that the fraudsters also have such a plan. At this time, the tide of shopping on double 12 and new year's day comes one after another, and people working outside are also busy booking tickets and air tickets for the Spring Festival, which provides opportunities for fraudsters. Here, liewang, the first online fraud information reporting platform linked by the police and the people in China, makes an inventory of the new trends of online fraud in 2017. Can you see through all these scams
trend 1: mobile payment has become the mainstream, beware of two-dimensional code trap
mobile payment has greatly facilitated people's life and made people travel easily. However, there are many criminals who use the way of scanning two-dimensional code to carry out fraud, which is impossible to prevent. For example, on bike sharing, a fake QR code is used to cover the regular QR code, and the avatar is set as the official icon of bike sharing to cheat users to pay or recharge; Next to the store's two-dimensional code, there are words full of temptation, such as "scan code to grab red packets", "scan code discount", etc., to lure users to scan the code, and then obtain user information or directly guide users to transfer money. There are even criminals who the illegal parking notice posted on the car by traffic police. The fake ticket is attached with a payment QR code to lure the car owner to scan the code to pay a "fine"
trend 2: fake businesses want to refund. Users should be careful of being" loaned online "
generally, people think that their bank card balance is small, even if they encounter swindlers, it doesn't matter. However, according to the report cases received by liewang platform, In the common refund fraud in 2017, fraudsters use mobile phones to receive SMS verification code to lure victims into Internet micro loan business, and finally transfer the loan to the swindler's account. This kind of fraud often involves a high amount of money and brings serious property losses to users
trend 3: mobile phones also contain extortion virus, and the payment method is more" people-friendly "
mobile phone extortion software has become a common tool for criminals to seek benefits e to its low proction cost and fast cash flow. At present, there are different forms of blackmail software in the mobile application market. Different from the blackmail software in the computer, bitcoin is needed to pay for it. The payment form in the mobile blackmail software is more "people-friendly"
a batch of blackmail software captured in 2017 attached wechat two-dimensional code information to the blackmail interface, and prompted the winner to directly scan the two-dimensional code for payment by wechat, which will automatically unlock after successful payment, and the user will automatically enter the transfer interface after scanning the code. However, through technical analysis, this kind of blackmail software does not have any code related to wechat transfer. The so-called "scan payment, automatically unlock" is actually a fraud, even if the user transfers, it will not automatically unlock
trend 4: fake customer service requests to provide payment code and swipe only by numbers
because code scanning payment is simple and convenient, in 2016, many fraudsters took a screenshot of the two-dimensional code to swipe. But in 2017, as payment companies added anti fraud tips or confidentiality settings in the process of payment QR code screenshots, swindlers immediately thought of countermeasures and swindled the numbers under the payment code, forming a new instrial chain
criminals often disguise themselves as merchants customer service, requiring users to provide figures such as Alipay, WeChat and other payment bar codes, and then, on the grounds of digital failure, require users to refresh the numbers and send them several times to achieve the purpose of stealing. p>
trend 5: download the specified software, but the account password is shared by cloud disk
users' privacy information can be stolen without using phishing websites and Trojan horse software. This year, swindlers have come up with new tricks: as long as the victims' trust is obtained, they can download cloud disk, synchronization software and other procts, log in to the account designated by the swindler to upload files and synchronize, and then they can easily get information. What's more, if the user synchronizes the SMS verification code at any time, the swindler can easily steal the funds in the bank card
fraudsters often disguise themselves as e-commerce, suppliers and other customer services, requiring users to download some cloud disk synchronization software, and then provide the specified account password for users to log in. At this time, if the user logs in and synchronizes the personal account, password and other information on the software according to the swindler's instructions, the funds on the account will be transferred quietly
trend 6: new phishing websites on mobile terminals are more covert and easy to be recruited
as security manufacturers increase their efforts to crack down on phishing websites, phishing website makers also strengthen their covert means, spread links by using proct sharing functions such as short URL, cloud disk service, browser and social tools, and finally jump through the URL, Guide users to phishing sites to launch online fraud
trend 7: indemnity should be paid in intimate way. Be careful with this kind of fraud SMS
as early as 2013, 360 company discovered a high-risk fraud binding the victim's online banking account. In recent years, with the use of mobile payment becoming more and more popular, In 2017, there was a similar kind of fraud, which used a payment platform to bind accounts and swipe victims' accounts
in May 2017, Mr. Di received a flight delay text message sent in the name of the airline, with flight information and customer service phone number attached in the text message, and said that Mr. Di could get 300 yuan of delay compensation. Fake customer service in the phone to guide Mr. Di refund operation, and provide the enterprise account, but also ask Mr. Di to open intimate payment function. However, after Mr. Di opened, he found that he had two dections, and realized that Mr. Di was cheated and immediately called the police
trend 8: investment in the circle of friends? Do not gambler psychology
in everyone's wechat group or circle of friends, there are often many activities or proct recommendations under the banner of discount. Not long ago, Mr. Wang saw a WeChat official account named "double half price win" in WeChat group chat. Mr. Wang then identified the official account as having an enterprise certification and believed that the platform had high credibility. p>
Mr. Wang invested a small amount in the early stage, and found that there was a certain income every day, so he subsequently invested in batches, but graally began to lose money“ He wants to invest more in order to earn back the capital. As a result, when contacting customer service again, he found that the other party had blackmailed him. Only then did he realize that he had been cheated and that the money he had invested had gone to nothing
trend 9: identity impersonation has a new pattern, be careful that "friends" are high imitations
in the past, online fraud of identity impersonation often occurred on QQ, wechat and other social platforms, but this year, swindlers shifted their focus to microblog. The swindler specially studies the social habits of the victims, such as the relationship between microblog staff and chat content, and then changes their avatars and nicknames to create high imitation numbers. Because most of the fake users are abroad, it is difficult for their microblog friends to distinguish the true from the false in time
trend 10: the combination of various means makes it impossible to prevent the" ghost "fraud.
in March 2017, 360 assisted the Shenzhen police in successfully cracking down the" midnight ghost "Telecom fraud Gang, which the police identified as an illegal trade instry chain relying on personal information, It is a high-tech, high intelligence, cross platform, remote-control new type of telecom network fraud crime that combines mobile cloud service, operator's deputy number service and Internet financial service. And this kind of stealing brush mainly uses different services of various platform service providers. A single service does not have the security risk of stealing brush, but it is combined to form stealing brush. In order to make it difficult for the victims to detect, the criminals choose to commit crimes late at night. The whole process does not need to have any contact with the victims, and the victims do not need to reply to any SMS, so prevention is very difficult
from the above ten cases, the current situation of network fraud is still not optimistic. The anti fraud experts of liewang platform hereby remind the netizens that the new year is approaching, the fraudsters are highly active, and all kinds of fraud means emerge in endlessly. At this time, we need to improve the anti fraud awareness, so that the fraudsters have no chance to take advantage of it
