1. What is GEC model? Cloud mining machine
as a platform with the highest currency price in cloud mining machine project, GEC has been imitated all the time<
10 RMB miner digs 11 RMB in 30 days
100 RMB miner digs 120 RMB in 30 days
1000 RMB miner digs 1300 RMB in 30 days
10000 RMB miner digs 14000 RMB in 30 days
in fact, this is a static income. With the currency price unchanged, your interest rate in one month is between 10% and 40%, which can be increased dozens of times in one year after re investment. In addition, the currency price promised by the platform will always increase steadily, One year's income is estimated to be hundreds of times, who is not interested
in order to quickly develop to members, all cloud mining machine projects are registered to proce 11 yuan per month. Because there is no money in the early opening market, people who want to invest can not receive money, so they can only continuously raise the price of money. One month later, a large number of sheep and wool parties began to sell goods, and investors wanted to buy at a low price, resulting in the continuous decline of money price,, The more severe the drop, the more people sell. Until all platforms sell at a low price, no one dares to continue to close. This is why most platforms die within two months. Even after barely spending the first two months, there are still a large number of new users registering every day. Every new user means 11 more free coins. The increase of wool coins will make it difficult for the price of coins to rise
GEC and eco have lived a long time since last year. I'm not advertising for them here, but I don't recommend you to play, because they are basically taking orders
in March this year, a lot of crowdfunding cloud mining machine projects were launched. It can be said that all of them were dead, and they couldn't survive for a week. It was a complete scam. They are all under the guise of crowdfunding 3 points and opening 1 yuan. After all, it costs a lot to buy coins from other users, and the proceres are complicated. If you buy tens of thousands of coins directly from the platform, the cost is low and the profit is large. In the case of too few user groups, a large number of coins appear, which will only break and will not grow. In addition, platform crowdfunding makes a lot of money, and they don't pay attention to the development of the platform. They just think about how to get away from it. Many crowdfunding platforms close their websites and disband their groups after crowdfunding
everyone can build such a website. If you can program, you may only need to spend less than 1000 yuan to buy a set of source code on Taobao. Revise it yourself
if the programming is blank, you need to spend about 2W RMB to buy a full set of templates and services< As like as two peas as like as two peas as like as two peas, Br />
this is why all cloud mine machine models are exactly the same, the frames are exactly the same, what the contents are exactly the same, even the mine machine icons have their own logo. Such a platform is not a blockchain project at all. The amount of money is controlled by the platform itself. To make money on the platform, it is to sell money to investors secretly. Many people have changed from investors to fleecers just because they know the trick
the so-called trading platform is just a joke. A currency that doesn't even have a digital wallet, and a currency that can change the quantity at will, which exchange will accept it
what is your personal thinking? Making a sum is a sum. You can't think for a long time, and you can't add new functions to the platform. Therefore, I personally suggest that you should be careful when investing in this cloud mining platform, especially if it doesn't run smoothly. Even a better server is reluctant to invest. How can we develop this platform with our heart
If a platform wants to develop for a long time, it is not the same layer. It needs to be adjusted according to the development situation in different periods. The most important thing is to have actual application scenarios. No matter bitcoin or these air coins are supported by actual application scenarios, they will graally disappear with the passage of time.

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband
extended data
users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes
3. If you want to dig a mine, you should understand these first, and then decide whether to join the army of miners or not
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
