recently, "bitcoin broke through $8000" has been on the hot search. For a while, bitcoin rose, reborn rose sharply, and Ethereum led the rise... A week later, this big play dominated by bitcoin didn't seem to come to an end, and the trading volume was once pushed up to 100 billion US dollars
in the investment world, "madness" and "fear" coexist. Today's "madness" stems from last year's long-term "fear". However, this time, coincola Cola Research Institute tracks and analyzes the technical indicators behind the rising market, and deconstructs the "passion" of the market with the "rationality" of data< (1) mining and bitcoin price
start with the relationship between mining and bitcoin. The core technology of bitcoin is "blockchain", which is connected by blocks. Each block corresponds to a bill. All transaction information and transfer records of bitcoin are recorded on the blockchain. Every other point in time, the bitcoin system will generate a random code on the system node. Due to distributed accounting, all computers on the Internet can search for the code. Whoever finds the code will generate a block and then get bitcoin. This process is mining. Calculating this random code requires a lot of GPU operations, so miners need to use mining machines with massive graphics cards to make profits
1. Bitcoin computing power: starting to pick up
remarks: June 2018-may 2019 bitcoin hash value
data source: bitcoin visual, coincola Research Institute
the above figure shows the bitcoin hash value. The hash value of the bitcoin network represents the computing power of the blockchain. The growth of computing power means that miners increase mining investment or increase the number of miners. Since the second half of 2018, the hash value has recovered from falling back to picking up, from 32eh / s at the end of the year to 50eh / s now, and the recent growth trend is remarkable. The continuous growth of bitcoin hash value (representing computing power) indicates that the market is optimistic about the future of bitcoin
2. Mining difficulty: stepped up
remarks: bitcoin difficulty from June 2018 to may 2019
data source: bitcoin visual, coincola Research Institute
the figure above shows bitcoin difficulty. Since 2019, the difficulty of bitcoin mining has increased in a step-by-step manner, from the low 5T to the current 7T. It can be seen that the rapid rise of bitcoin in this round has reced mining costs and increased market entry personnel. The increasing difficulty of mining means that there are profit opportunities in cryptocurrency market, and the market is generally optimistic< (2) the number of active addresses and transactions on the chain are important indicators reflecting the activity of cryptocurrency, which are highly correlated with the price of cryptocurrency
1. The number of active addresses on the bitcoin chain: a straight line rise
remarks: the number of active addresses on the bitcoin chain from June 2018 to may 2019
data source: coinmetrics, coincola Research Institute
active addresses refer to the addresses where transactions have taken place every day, that is, how many independent addresses conct transfer transactions on the chain every day. Since 2019, the number of active addresses on the bitcoin chain has been rising, especially in recent years. From 540.60143k in January to 832.592k now. It shows that the rapid growth of active users of cryptocurrency is a very positive signal for the market
2. The number of transactions on the bitcoin chain: continued to rise
remarks: the number of transactions on the bitcoin chain from June 2018 to may 2019
data source: bitinfo charts, coincola Research Institute
since 2019, the number of transactions on the bitcoin chain has continued to rise, from 235k in early 2019 to 374k now. Moreover, since April and may, after two rounds of sharp rise in the price of bitcoin, the number of transactions on the chain has remained at a high level, even showing signs of a short-term surge< (3) lightning network and bitcoin price
in essence, lightning network adds a layer to the basic layer of bitcoin blockchain in order to make the transaction fast and cheap. With the existence of lightning network, users can remit money to each other at any time and pay very little. Lightning network represents not only the technical level of bitcoin, but also the important basis of bitcoin value
1. Lightning network nodes: rapid growth
remarks: bitcoin lightning network nodes from January 2018 to may 2019
data source: bitinfo charts, coincola Research Institute
the test version of lightning network started on the bitcoin main network on March 15, 2018. The number of lightning network nodes was only 64 at the beginning of 2018 and increased to 2329 at the end of 2018. Since 2019, the number of lightning network nodes has increased rapidly, and now it has reached 4289. In less than half a year, the number of nodes has doubled. The continuous expansion of nodes indicates the continuous upgrading and development of bitcoin lightning network technology, which is an important indicator of bitcoin price
2. Lightning network capacity: speed up
remarks: bitcoin lightning network capacity from January 2018 to may 2019
data source: bitcoin visual, coincola Research Institute
the data above shows that as of May 15, 2019, bitcoin lightning network capacity has increased to 1039 BTC, equivalent to 833usd, while at the beginning of 2019, it is only 504btc, Lightning network capacity doubled, and the growth rate accelerated. This means that the expansion of bitcoin has been well solved in lightning network technology, which will help keep the payment channel active and effectively support the functional application of bitcoin
the performance of mining, chain trading and lightning network is closely related to the price of bitcoin. On the one hand, the rise of bitcoin price acts as a catalyst to stimulate its performance in mining, chain and lightning network; On the other hand, mining, chain trading and lightning network are the important cornerstone of bitcoin price trend and the important basis of bitcoin price expectation<

the prediction about the collapse time of bitcoin
yesterday, he discussed bitcoin with people, and then suddenly found that the surge brought by the listing of futures may be the pit g by some big institutions, Bitcoin could collapse shortly after CME's CBOE listing. After the listing, the price will maintain a certain stability in a certain range
Short refers to selling positions, can also be called use, sell a certain type of currency loans, bullish. Do long: do and refer to the multi warehouse, can also be called Lido, also known as multi warehouse. Buy some kind of loan currency and be bearish
Long means that the price will rise after estimation, so buy the contract and sell it at sky high price after the price rises in the future. Net profit. Short selling means that the potential will fall after estimation, so sell the contract and buy the contract at a low price after the price falls in the future. Net profit2. For hedging: to be long means to evade or wash away the risk of proct cost expansion caused by future price rise, and lock up the cost in advance. Short selling means to evade or wash away the risk of profit rection caused by the price decline in the future, and lock in the profit ahead of time

burst, under some special conditions, the customer's equity in the investor's margin account is negative. When the market changes greatly, if most of the funds in the margin account of investors are occupied by trading margin, and the trading direction is opposite to the market trend, it is easy to burst e to the leverage effect of margin trading
if the position explosion leads to the deficit and is caused by the investors, the investors need to make up the deficit, otherwise they will face legal recourse. The bigger the leverage is, the closer it is to the burst. We should be cautious when adding any leverage

Bitcoin market can be seen on many platforms, but the premise of these is that you can see it and find a reliable proct platform
here is an example, such as coinplus exchange
1. First, go to the official website of the Canadian dollar station, and then look at the home page
the key point is that the platform is very intimate, and even the download steps have direct guidance
the above are just personal opinions, which can be referred to and guided
Bit / S is the unit of information transmission rate. Symbol transmission rate is also called molation rate, waveform rate or symbol rate. A symbol does not necessarily correspond to a bit
symbol:
in digital communication, symbols with the same time interval are often used to represent a binary number. The signal in such time interval is called binary symbol, and this interval is called symbol length
symbol
is a sinusoidal carrier [its length is the symbol length] used to represent a certain phase or amplitude value of a digital code type [different bits correspond to different keying molation modes]
symbol rate is the conversion rate of carrier signal parameters (such as phase), which is actually the change rate of carrier state. The higher the symbol rate is, the higher the transmission rate of the response is. However, the higher the spectrum component in the signal is, the wider the bandwidth is occupied
baud rate
is the molation rate or symbol rate, which refers to the baud number per unit time after the signal is molated, that is, the number of carrier parameter changes (phase or amplitude) per unit time. It is a measure of signal transmission rate, usually in "baud per second" (BPS)
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released
bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner
This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 millionbitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
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.
PN is the rated power
rated power PN refers to the rated active power output by the generator, that is, the maximum active power that can be generated by the synchronous generator under rated operation (rated frequency, voltage, current and power factor). Generally, the unit is kW or MW
for synchronous generator, the rated current can be determined by rated capacity (SN), and the capacity of matching prime mover can be determined by rated power (PN)
motor rated power PN (kw) = √ 3 × Un × In × cos φ×η
where UN --- rated voltage (kV), in --- rated current (a), cos φ--- Power factor, η--- Motor efficiency
extended data:
the selection principle of motor rated power should be the most economical and reasonable selection of motor rated power on the premise that the motor can meet the requirements of proction mechanical load
In other words, the rated power of the motor should not be too large or too small. If the power is too large, the efficiency and power factor of the motor (AC motor) will be reced, resulting in a waste of power and extremely uneconomic. On the contrary, if the power selection is too small, the motor will be overloaded and the service life will be shortened, or even burned; Or in the case of ensuring that the motor does not overheat, can only rece the use of the load Therefore, the motor power should be selected according to the load power
