Btc2017 curve
BTC, usdt, ETH, BCH, LTC mean respectively:
1, BTC
bitcoin. The concept was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software is designed and released, and the P2P network is built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
2, usdt
TEDA currency is a virtual currency that links cryptocurrency with legal currency US dollar, and is a virtual currency kept in foreign exchange reserve account and supported by legal currency
EthEthereum is an open source public blockchain platform with intelligent contract function, which provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether
4. BCH
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers
at 20:20 on August 1, 2017, bitcoin cash starts mining, and each bitcoin investor's account will have the same amount of bitcoin cash (BCH)
5, LTC
litecoin, abbreviated as LTC, currency symbol: & # 321;; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

bitcoin has entered the downward channel, showing a cliff like decline
since then, bitcoin has entered the downward channel, and the myth of bitcoin's sudden wealth is being shattered. According to the latest data of the "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, on June 25, bitcoin fell to US $6160. The previous trading day, bitcoin fell below US $6000, a new low in the past six months. Compared with the record high of US $19187 in December 2017, the decline was as high as 68%
the total number of bitcoin is 21 million. According to this estimate, the total market value of bitcoin in December last year was as high as US $402.9 billion, and now it has shrunk to 129.36 billion yuan. In the past six months, the total market value of bitcoin has evaporated US $273.567 billion, which is about 1.79 trillion yuan at the current exchange rate
at the same time, other cryptocurrencies also fell. Ethereum eth has dropped from a peak of $1350 at the beginning of the year to around $454.9 at present, with a cumulative decline of 66%. The LTC of Leyte currency dropped from the highest of $342.25 in December last year to the current $80.99, with a cumulative decline of 76.34%
the negative feedback of price decline is being transmitted in the instrial chain. Under the pressure of cryptocurrency market price, bitmain and Canaan, the top two Chinese manufacturers of bitcoin mining machines, may cut 50% of the orders of chip companies TSMC and Samsung Electronics
stricter supervision is a sign of chaos
stricter supervision worldwide is the main reason for the sharp decline of cryptocurrencies such as bitcoin
on June 22, Japan's Finance Department officially issued an order to improve the business of six cryptocurrency exchanges, including bitflyer, quoine, bitpointjapan, bitbank, btcbox6 and tech
Bureau
bitflyer, Japan's largest digital currency exchange, immediately suspended the opening of new accounts and carried out rectification, especially in its anti money laundering and control of terrorist funds. Japan has developed into one of the largest bitcoin trading markets. As soon as the news came out, the price of bitcoin fell to a new half year low
on June 10, coinrail, the cryptocurrency exchange of South Korea, said that its system had suffered "network intrusion", which also led to a sharp drop in bitcoin after its opening
judging from the change of regulatory attitude, countries have previously held an open and embracing attitude towards blockchain technology. However, with the rising price of bitcoin and the increasing use of ICO for illegal financing, the application of blockchain technology has "deteriorated", the speculative activities have increased significantly, and the cross-border capital outflow has been boosted, The attitude of regulators is also changing
the tightening of supervision will lead to the shrinkage of trading volume and the decline of activity, because the pricing mechanism of bitcoin price is highly positively correlated with the number of participants, which will lead to the decline of bitcoin price. Of course, we don't think bitcoin or digital currency will die out. As long as there is a trading caliber in the world, bitcoin will not die out. It's just a decline in valuation
blockchain technology - a potential change technology in the future
the "hype" capital of bitcoin represents the capital with strong risk preference in the financial market. Bitcoin is characterized by decentralization. As a distributed virtual currency, bitcoin is charged by users independently, and there is no unified regulatory core, such as the Central Bank of each major economy that supervises legal currency. Moreover, the development of bitcoin markets in different countries is different, so it is difficult to coordinate and supervise them. The characteristics of bitcoin make it more speculative
from the perspective of diffusion, bitcoin's recent sharp decline may be transmitted to risky assets such as stocks and commodities, which will depress the risk preference of the global capital market
block chain technology is not a bubble in itself, but bitcoin may be a bubble. Bitcoin is the first representative application of blockchain, but blockchain is not the same as bitcoin. The decentralized and distributed storage of blockchain technology has great application value. It is a potential new technology in the future. It is optimistic about the development of blockchain technology for a long time.
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it
mining is definitely the first professional mining machine. Many new children's shoes will choose to mine with graphics card. However, mining with graphics card is just like doing a professional job with "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.
by 2140, the total number of bitcoins was 21 million. I suggest you buy it< In 2009, a mysterious hacker named Satoshi nakomoto first proposed the concept of bitcoin, and described a method of using computer networks to create an unmanaged "secret currency". Unlike other virtual currencies, bitcoin is not issued by a company or a central bank, nor linked to any real currency, but can be used to buy goods and services in the real world. In essence, it can be seen as a small string of encrypted code quickly transmitted and stored in the electronic wallet on the Internet. Just as the P2P networks such as Napster and Skype once made the record instry and telephone instry into a mess, bitcoin, which challenges the modern monetary and financial science, is also based on P2P - the same as our commonly used BT download technology. The advantage of P2P is to ensure that no institution can manipulate the value of bitcoin or increase the supply to create inflation. In a huge P2P network, bitcoin has a special algorithm, which proces about 300 bitcoins per hour. This output is automatically adjusted by the network. Because you can't control most of the network nodes, you can't modify the algorithm of each user to speed up the money proction. Figuratively speaking, bitcoin is "mined" by computers all over the world. If you want to get bitcoin, you just need to install mining software, and your computer will start to do a lot of calculations, which is mining. No matter which computer is used to mine, it is easy to get 50 bitcoins in the early days of bitcoin. As early as January this year, 50 bitcoin was not worth $15, but on June 9, a bitcoin was worth as much as $29.55. If you trade them, you can get back $1500 of real gold and silver. Now, however, mining requires high-performance computers, and some developers involved say that it is estimated that an ordinary laptop will work for five years to get a bitcoin. Why is that? We have to start with the currency itself. Economics tells us that money exists because of transactions. The value of bitcoin lies in the transaction itself. In order to transfer bitcoin from one account to another, there must be a secure channel. To create a secure channel, a lot of energy will be consumed. Therefore, the whole bitcoin user group should reward the mint (50 bitcoin). In other words, he succeeded in mining. Mining, in essence, is the process of creating new blocks (each block contains 50 bitcoin) on P2P network. In short, the software algorithm determines that it is difficult to create a new block that is recognized by the whole network. If there are more participants, the new block will be generated more slowly. Just like mining, with the depletion of the most accessible resources (assuming no newly discovered mineral deposits), the supply will graally decrease. According to the algorithm, each block can only generate 25 bitcoins by 2013, 12.5 bitcoins by 2017, and so on. By 2030, the total number will stay at a platform, about 21 million. Graphically, this will be a flat curve. Reality also proves this point. As the value of bitcoin rises and the number of participants increases, mining becomes more and more difficult. At the forum, miners discussed how to use dry ice and liquid nitrogen to cool computers, increase CPU frequency and speed up mining software, or customize top computer graphics cards and improve network speed to proce more bitcoin. According to the guardian, someone was mysteriously mining at home, and even was suddenly attacked by the police, who mistook him for drug trafficking. Recently, Symantec, a digital security company, discovered a new trojan virus. This malicious program, coinbit, is used to steal numbers, so that hackers can easily break into users' bitcoin wallets and steal their contents. Before the June 19 incident, members of the lulzsec hacker group and anonymous team had discovered that there was a better way to mine - to use someone else's computer. These hacker groups are famous for their server attacks mainly relying on botnets. Some members found that some miners actually use their botnets to mine. The miners are also said to be hackers, who have used botnets to control more than 100000 computers. With the scale of the current network, the efficiency of mining can be greatly improved. It is estimated that 400 to 500 bitcoins can be proced every day, and the current value is more than 8000 US dollars (as of June 28, 2011, 1 bitcoin = 16.9 US dollars). There are two groups of people in the bitcoin community. One group denies that someone is using botnet to mine. The other group says that this is a fact and admits that botnet computing has dropped dramatically. An anonymous person said it was clear that there were people who thought that participation in mining would be more rewarding than attacking mining.
after two consecutive days of plummeting, according to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, on June 13, Beijing time, the price of bitcoin fell below $6500, the lowest level since February this year. Bitcoin used to cost $6463. Since the beginning of this year, cryptocurrency has faced more and more resistance. Bitcoin, which has the largest total market value, has been fluctuating since it reached a record high (nearly US $20000) in December last year, with a cumulative decline of about 50% this year
from the United States, South Korea, Japan and other governments' supervision of cryptocurrency to the prohibition of cryptocurrency trading by visa, Bank of America and other large financial institutions, and to the prohibition of cryptocurrency advertising by internet giants such as Facebook, Google and twitter, the price of bitcoin has been aggravated by the recent multiple bad news
several exchanges were stolen
on June 10, coinrail, the cryptocurrency exchange of South Korea, was attacked by hackers, and more than US $40 million of unknown cryptocurrencies such as pundi
x were stolen. Subsequently, the prices of bitcoin, Ethereum, reborn and lightcoin all dropped more than 10% in one day
on June 29, 2017, bithumb, the largest bitcoin exchange in South Korea and the top five in the world, was found to have been hacked, and more than 30000 customers' personal information was stolen. According to the market value at that time, the loss amounted to 7.6 billion won
on January 26, coincheck, the largest trading volume exchange in Japan, suspended the trading of all cryptocurrencies except bitcoin. The trigger was that hackers attacked 260000 users and stole NEM, a new digital token, with a loss value of about US $530 million
bitcoin is likely to graally lose its loyal fans
bitcoin is now a widely recognized financial asset in the financial market, and many factors will lead to its price fluctuations, such as the expectation of the Federal Reserve to raise interest rates. At present, this round of price adjustment is still in progress since the beginning of the year. After all, in 2017, the price of bitcoin soared more than 20 times
bitcoin has been sold. From December 2017 to April 2018, bitcoin worth 30 billion US dollars has been sold. According to chainalysis, bitcoin's market liquidity has increased by nearly 60% in recent months. Bitcoin is likely to be losing its fans
the initial growth of bitcoin does rely on loyal fans. In recent years, the demand for investment has increased. However, bitcoin is still an asset with strong consensus foundation in the blockchain field, and long-term holders may waver. However, when they find that other cryptocurrencies are more risky, bitcoin may return to the vision of investors
since the beginning of the year, the price of bitcoin has been in a bear market cycle. At present, the bear market is still going on, and the periodic rebound will be obvious, but the overall situation is still in a weak adjustment. The probability of further weakening is relatively large, but the space will be relatively small.
