Number of mining machines in Babbitt mine
Under the current difficulty, 1t mining machine can dig about 0.0268 BTC per day, which is about 1 bitcoin in 50. It is about 100 yuan in RMB. How much bitcoin you can dig in a day depends on how many shares you hold, that is, computing power. However, the computing power is floating. When the overall computing power is low, it's more. Otherwise, it's less. You can go to Babbitt's website to check the specific content when you have time< br />

extended data:
the characteristics of blockchain
1. Decentralization
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness
the foundation of blockchain technology is open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
Blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp
time stamp refers to the string or encoding information used to identify the recorded time and date. The international standard is ISO 8601
Turing completion refers to the ability of a machine to perform calculations that any other programmable computer can perform DAPP decentralized application is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of cryptocurrency token, and operates with protocols showing valuable proof Dao, a decentralized autonomous organization, can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules13. Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key
is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network
for those who don't know the "jargon" in the currency circle, let's learn it as soon as possible:
1. What is legal currency legal currency is legal tender, which is issued by the state and the government. It is only guaranteed by the government credit, such as RMB, US dollar and so on 2. What is a token token, usually translated into token. Token is one of the important concepts in blockchain. Its more well-known name is "token". However, in the view of professional "chain circle" people, its more accurate translation is "token", which represents a proof of rights and interests on the blockchain, rather than currency token one is digital proof of rights and interests, which must be in the form of digital certificate of rights and interests, representing a right, an inherent and intrinsic value
3. What is warehouse building
the establishment of a position in a currency circle is also called opening a position, which refers to a trader's new purchase or sale of a certain amount of digital currency
What is Sohasuoha refers to investing all the principal
What is airdrop
airdrop is a very popular marketing method of cryptocurrency. In order to let potential investors and cryptocurrency enthusiasts get token related information, token teams often air drop tokens
6. What is lockup position locking generally refers to investors opening a new position opposite to their original position when the market moves in the opposite direction after the sale and purchase contract, which is also called lock, lock order, or even butterfly double flying doughnut candy is a kind of free digital currency issued to users when all kinds of digital currencies are just issued in ICO. It is a kind of momentum and publicity of the project itself by the issuers of virtual currency projects
breaking refers to falling below, and issuing refers to the issuing price of digital currency. Broken currency circle refers to the price of a digital currency falling below the issue price
What is private placementprivate placement is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operation
What do you think of the K-line diagram
K-line chart is also called candle chart, Japanese line, yin-yang line, bar line, red and black line, etc., commonly referred to as "K-line". It is based on the opening price, the highest price, the lowest price and the closing price of each analysis cycle
What is hedging
General hedging refers to two transactions which are related to the market, opposite in direction, equal in quantity and balanced in profit and loss. In the futures contract market, buy the same number of positions with different directions. When the direction is determined, close out the positions in the opposite direction and keep the positive direction to make profits
What is the positionposition is a kind of market agreement, which promises the initial position of the sale and purchase contract, and the buyer is long and in the expected position; The selling contract is short and in the expected position

Babbitt has a bitcoin mining income analysis article, which has a figure for reference. According to its calculation, it's 132 days
. It's said that BTM batcoin has changed its name to btme now. No matter what it is called, it can't change the business of cheating investors. Now it's just cheating others to invest. This is a fake disk (a pyramid selling coin fraud project packaged with blockchain, which can charge phone charges and have business success. These things are for you to buy on Taobao. They can cheat you to invest money and connect with mainstream currencies, As long as you have money, it's better to go to the exchange and buy directly. It's no more than letting the little white who doesn't know to take over the plate. The currency has become a flood. It's bullshit to go to the trading platform. A fraudster plays with blockchain and virtual miner for pyramid selling. Your real gold and silver will soon be exchanged for a pile of useless numbers.) pyramid selling currency: in the guise of blockchain technology, the technology is far from the real blockchain principle; Not to solve, optimize or change a business pain point of traditional instry as the purpose; The token is not released through the smart contract of Ethereum, and there is no formal trading platform for digital currency, most of which are traded through the platform built by the project party; Promise to rise but not fall; When you pull your head in, it pays off< The suspect crowd financing unpunished by br / > about the BTM Bart currency fraud group, the mutual help disk and the crowd raising. Finally, the criminals played the block chain and the virtual mine pyramid sale. Now the fraudsters are still at large, and the public security organs are seeking the suspect of fraud to recover the losses of the injured netizens.
the so-called blockchain, the so-called virtual currency, there are several real, there are several real hash pH value and SSH encryption protocol! In addition to a few well-known old coins, other basic is not! That belongs to ICO Shanzhai coin? Counterfeit money! We should be cautious in investment! This year, fake blockchain, fake virtual currency, film and television dividends, football arbitrage, dividends, equity, mutual aid, points, fixed split, consumption all back, flying all over the world, everyone watch your pocket, don't let cheater disk bonus system, income to temptation! The packaging of many projects is very high and expensive. They are all paid to be packaged by others. The so-called videos are proced, the so-called white papers are also written by others, and the so-called open source code is also made by packaging companies. Now they are doing the so-called pioneering projects, and 99.99% of them are fraud projects! We are still not sober. At the end of the year, your pockets will be robbed by swindlers.
the conveyor is a general equipment, and the feeder is a special machine with high efficiency.
3. Mining is the most stable return so far. But first, you have to own your own mining machine, then choose your own mine, remember your account password address, and then plug in the power and network cable to start the machine, It's just that apart from the maintenance cost of electricity, there is also the risk of power failure, and there is also the risk of bitcoin proction halving every four years
4. Speculation or hoarding of money, trading in the over-the-counter or on-the-spot exchanges, buying transactions. It is suggested that novices should be more cautious when trading, and invest within the acceptable range, never be greedy
3. If you don't want to get your own money, you can damage the media / we media, etc.
mainstream instry media such as Babbitt information, golden finance, thousand krypton finance and so on, such as thousand krypton finance can get the corresponding income for free through a series of operations, as long as you seriously read articles or share articles with friends on the platform, It's easy to get a few hundred dollars a day
4. As for ICO, I don't recommend the owner to try it. The risk of ICO is great, and it will be classified as illegal in China
5. There are still many ways to invest in blockchain concept stocks~~
If the power frequency is 50 Hz, the maximum speed of the 2-pole motor is 3000 rpm, and that of the 4-pole motor is only 1500 rpm. If the power frequency is increased to 400 Hz, the maximum speed of the 2-pole synchronous motor can reach 24000 rpm, and its rule is n = 60F / P
extended data:
permanent magnet synchronous motor can be installed on the axle as a whole to form a whole direct drive system, that is, an axle is a drive unit, eliminating a gearbox. The main characteristics of PMSM are as follows:
(1) PMSM has high power efficiency and high power factor
(2) PMSM has small heating, so the cooling system of the motor is simple in structure, small in volume and low in noise
(3) the system adopts fully enclosed structure, no transmission gear wear, no transmission gear noise, no lubricating oil, no maintenance
(4) the PMSM allows a large overload current and its reliability is significantly improved
(5) the weight of the whole transmission system is light, the unsprung weight is lighter than that of the traditional axle transmission, and the power per unit weight is larger
(6) since there is no gearbox, the bogie system can be designed at will, such as flexible bogie and single axle bogie, which greatly improves the dynamic performance of the train Relevant characteristics of permanent magnet synchronous motor:1. Voltage regulation
automatic regulation excitation system can be regarded as a negative feedback control system with voltage as the regulated quantity. Reactive load current is the main cause of generator terminal voltage drop. When the excitation current is constant, the generator terminal voltage will decrease with the increase of reactive current
However, in order to meet the user's requirements for power quality, the terminal voltage of the generator should basically remain unchanged, and the way to achieve this requirement is to adjust the excitation current of the generator with the change of reactive current2. Regulation of reactive power:
when the generator runs in parallel with the system, it can be considered that it runs with the bus of infinite capacity power supply. To change the excitation current of the generator, the inced potential and stator current also change, and the reactive current of the generator also changes
when the generator runs in parallel with the infinite capacity system, the excitation current of the generator must be adjusted in order to change the reactive power of the generator. At this time, the change of generator excitation current is not commonly referred to as "voltage regulation", but only changes the reactive power into the system
3. Distribution of reactive load:
the reactive current of generators in parallel operation is distributed in proportion according to their rated capacity. Large capacity generator should bear more reactive load, while smaller capacity generator should bear less reactive load
in order to realize the automatic distribution of reactive load, the excitation current of generator can be changed by the excitation device with automatic high-voltage regulation to keep its terminal voltage unchanged, and the inclination of generator voltage regulation characteristics can be adjusted to realize the reasonable distribution of reactive load of parallel generators
