The largest and earliest mining project

1. False. It's impossible and unscientific

2. Exchange: bit-z
trading mining online time: June 2018
Project Introction: bit-z, founded in Hong Kong in 2016, provides digital asset trading and OTC (over-the-counter trading) services
dividend method: "transaction mining". Users who participate in the transaction can get a refund of service charge (in the form of equivalent BZ, and need to complete three-level certification); Each phase of 10 million BZ will be released step by step, and each phase of 10 million BZ will automatically enter the next phase. The return ratio of each period will decrease by 3%
total number of tokens issued: 1.2 billion BZ.

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

4. The selection of mining machines depends on the computing power, the power consumption and the historical reputation, including the stability and after-sales service of the machines
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of the mainstream bitcoin miner is 14T, that is, hash collisions of the 13th power of 14 times 10 per second
power consumption is an indicator of the power consumption of the miner ring operation. Electricity consumption will have a huge relationship with mining costs. Generally, a miner will operate 24 hours a day to excavate, so the power consumption sometimes seems to have a small difference, but in fact, the cost gap is relatively large
here is another little knowledge, that is, digital assets of the same algorithm can be mined by the same miner. For example, bitcoin miner can also dig bitcash, Ethereum miner can also dig Ethereum classic
for more professional knowledge, it is recommended to consult the honeycomb miner. There are professionals to help you select and answer for you. The boss comes from the fire coin, and I feel reliable after personal experience.

5. Ah, can bitcoin mining projects be approved? At present, the country does not recognize this piece, so your approval may be delayed or not

7. For those who don't know and have no experience in investment, I suggest you be cautious. After all, money is not easy to come by, and you should cherish it
what kind of bitcoin is is, in fact, a virtual and worthless thing. As for the Mining Fund, it's even more uncertain!

8. That depends on what type of mining projects, such as the current very formal ones are Xunlei mining, and quickcast mining, etc. in fact, there are others, but they haven't been tried yet. At present, these two projects are absolutely credible, and they are operated by large companies. Don't worry about running away!

1. For a job g, it may start early or late, but generally speaking, it starts early and finishes early, So: (see the textbook specifically)

(1) g earliest start time + ration = g earliest finish time

(2) g latest start time + ration = g latest finish time

(3) g total time difference = g latest start - G earliest start (minus sign)

(4) g total time difference = g latest finish - G earliest finish (minus sign)

2 The earliest start time of G = the maximum of the earliest completion time of the previous work

that is, the one whose previous work is completed the earliest and takes the most time. Short note: the earliest beginning is the earliest ending

G the latest completion time = the minimum value of the latest start time of the tight work. Note: finish at the latest, start at the latest, finish at the latest, finish at the latest, start at the latest, finish at the latest, finish at the latest, finish at the latest, start at the latest, max min

3. Find out the total time difference of a work g (commonly used method in comprehensive questions)

1) find out the total construction period first, find out the key line first

2) find out the time difference that contains work G The line with the longest ration (both conditions must be met)

3) the difference between the time of this line and

1) and 3) is the total time difference of G (don't ask why I don't know)

< H2 > extended data

example 1 --- in the double code network plan, the earliest start time of G is the 21st day, the ration is 6 days, and the total time difference of G is 4 days, G latest completion time

according to the above two formulas: G latest finish - G earliest finish = g total time difference, G earliest finish = g earliest start + ration

G earliest finish 21 + 6 = 27, latest finish - earliest finish = g total time difference

example 2: the earliest completion time of G work is the 12th day, lasting for 6 days, the total time difference of G is 7 days, and the latest start time of G

According to the formula: G latest start - G earliest start = g total time difference, G earliest start + ration = g earliest finish, first calculate the earliest start time: 12-6 = 6,

deformation: G latest start = g earliest start + G total time difference = 6 + 7 = 13

deformation problem 1: (synthesis)

G the latest finish time is the 25th day, lasting for 6 days, there are three urgent tasks, The earliest completion time is the 10th, 12th and 13th day respectively. G total time difference

gtotal time difference = g latest start - G earliest start, G latest start = g latest finish - ration, G earliest start = the maximum value of the earliest finish of the immediate work

first calculate g earliest start time = max (10, 12, 13) = 13, G latest start = 25-6 = 19, G total time difference = 19-13 = 6
