Ethereum sell down

1. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

2. bitcoin is an electronic currency proced by open source P2P software. digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin.". Short for: BTC
bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions have risks. You can invest cautiously. You can search online for fire coin, coin security, OK, dobby trading platforms, etc. all of which can trade bitcoin. These are relatively large trading platforms, investing in mainstream digital currencies, and Don't invest in counterfeit money or air money.

Bitcoin has opened the era of blockchain 1.0, which is characterized by providing a different way of thinking for value transfer, that is, value transfer no longer depends on centralized institutions such as banks. During this period, as more and more people were familiar with bitcoin, many people began to learn from the idea of bitcoin, so a large number of counterfeit coins appeared

the reason why these counterfeit coins are called "counterfeit coins" is that their source code is similar to that of bitcoin, and there is no substantive breakthrough. They also have the shortcomings of bitcoin, and there is no breakthrough improvement. However, people do not have the problem of bitcoin. Many people in the bitcoin community hope to solve these problems through a variety of technical means, so as to make the bitcoin system perfect

Among them, there is a Russian teenager named vitalik buterin, who is also eager to make up for the shortcomings of bitcoin system as soon as possible

first, you play games in a lively way, while others play games as gatekeepers

when he was 13 years old, he was a typical Internet addict, addicted to world of Warcraft. One day, the game company of world of Warcraft suddenly cancelled his favorite warlock "life siphon" skill. He was very angry and contacted the company many times to restore the skill. However, the game company did not agree

as a result, Butlin began to reflect that in Internet games, players, as participants, are actually very weak. The strong ones are game developers, who are the center of a game. Has the final say that the game player has no say what the developers want to do, and can only choose to accept or leave passively. p>

Butlin realized the disadvantages of centralization through "world of Warcraft", so he began to look for ways to break the centralization. Butlin realized bitcoin from his father, a programmer, and became so interested that he decided to give up the aura of a famous university and drop out of the University of Waterloo to travel around the world to exchange and learn with blockchain enthusiasts all over the world

at that time, bitcoin enthusiasts were going all out to add more functionality to bitcoin and build bitcoin 2.0. But Butlin believes that the establishment of a new programming language is bitcoin's top priority. So, at the age of 19, Butlin wrote a new white paper, which is the rudiment of Ethereum white paper. Butlin mentioned in the white paper

: he hopes to create a variety of applications based on the common programming language, such as social networking, trading, games... These ideas have been strongly echoed by the bitcoin community, and more and more people have joined in the design of Ethereum. Finally, this project was named "Ethereum" by Butlin, because "Ethereum" is a kind of material that has not been confirmed under scientific theory, implying Butlin's expectation for the project

in June 2015, Ethereum officially released

in the next two years, Ethereum's cryptocurrency "Ethereum" became the most popular digital asset after bitcoin. The price of Ethereum increased 85 times in 2017, and more than 20 global top financial institutions and technology companies, such as JPMorgan Chase, Chicago Board of exchange, Microsoft, Intel and Accenture, established the enterprise Ethereum alliance, Butlin has become a blockchain God "V God" from a young boy

2. The great potential of Ethereum to activate blockchain

the emergence of Ethereum has activated the great potential behind blockchain. Why do you say that

the breakthrough of Ethereum is that it not only upgrades the blockchain to an operating system, so that you can develop an application chain on this basis, but also allows you to publish your own tokens in a very simple way

different from bitcoin's preset trading system operation, Ethereum is a programmable blockchain:

Ethereum allows users to create their own operations that meet their needs and have different degrees of complexity. In this sense, Ethereum is a platform. This "platform" has built a relatively complete "system", which is a bit similar to Android and apple. Application developers can develop various applications on this system

this setting makes Ethereum break through the single "monetary function" of bitcoin, and expand the application scenarios of blockchain technology to all aspects. Now, for example, we can do a lot of things through mobile app: paying fees, ordering meals, taking a taxi, shopping and so on. Similarly, developers can develop DAPP (blockchain application) on Ethereum. In the future, you can use DAPP to replace app, paying fees, ordering meals, taking a taxi, shopping and so on. Ethereum gives us these beautiful visions

Thirdly, the consensus mechanism of Ethereum is different from that of bitcoin. As we mentioned earlier, bitcoin decides its bookkeeping rights through the consensus mechanism of pow. Although the security index of pow is high, the energy consumption and cost of mining are huge, and the transaction processing speed is still very slow. Therefore, Ethereum further enriched the technology of bitcoin and proposed a new mining mechanism, namely, proof of interest (POS)

The "proof of equity" proposed by Ethereum is similar to the shareholder mechanism. The more shares people have, the easier they are to obtain the bookkeeping right. It is a system of interest distribution according to the amount and time of holding money. The core logic of POS mechanism is: who holds the currency, who has the control of the network. It should be noted that in the POS mechanism, there is still computing power mining, which needs to solve a mathematical problem. However, the difficulty of the mathematical problem is related to the "age" of the coin holder. The longer the coin holder holds the coin, the easier the difficulty will be, and the greater the probability of digging the coin

Fourthly, the controversial ICO

Ethereum is an open source system, similar to the current Android and apple systems. Developers can develop various applications on it. Most of the ICO projects are based on Ethereum. If developers want to develop blockchain applications (DAPP) on Ethereum, they need to raise certain funds through ICO as operation and maintenance costs

The concept of ICO was very popular in 2017, which was once considered as the main reason for the bull market in 2017

What's the matter with ICO? ICO (initial coin offering) is a way to raise funds for digital currency / blockchain projects. Because the token has market value, it can be converted into legal currency. In this way, it can be used as the development cost of the project. And early participants can get the initial issue of digital currency in return

generally speaking, if a blockchain game company announces: we are going to issue money for private placement (ICO)! If you are particularly optimistic about this project, if you want to participate, you need to buy a certain number of Ethereum and call the wallet address of the blockchain game project party, which is equivalent to that you have participated in the crowdfunding (ICO) of the blockchain game project party. When the currency of this blockchain game company can be traded on the exchange, then they will pay you back according to certain rules

it seems that ICO in blockchain field is similar to IPO in stock field, isn't it? you 're right! In fact, ICO in the blockchain field is very similar to IPO in the stock field. Let's take a look at their general explanation:

IPO refers to an enterprise or company (limited company) selling its shares to the public for the first time

ICO refers to an enterprise or company (mostly blockchain start-ups) selling its token to the public for the first time

however, normally speaking, it is very difficult for an enterprise or company to go through the IPO process. It is very difficult to go through "BP seed round Angel round a round B round C round D pre IPO IPO IPO" without five to eight years. However, ICO in the field of blockchain can only be realized in three to eight months by "white paper - cornerstone investment - Private Placement -

- ICO - Stock Exchange"

This is also the reason why ICO is controversial. At present, many countries define ICO as an illegal act. It is not unreasonable to ban ICO, because at present, the state has no relevant supervision on this aspect, so it is very easy for the project party to illegally raise funds and circle money, which not only causes great losses to investors, but also disrupts the normal financial order

Fifthly, the most important feature of Ethereum is the introction of "smart contract". What does smart contract mean? Smart contract is to define a set of trading rules in the form of code. In our daily life, we usually sign paper contracts, and the implementation of paper contracts needs centralized institutions, that is, the court to supervise. The "smart contract" proposed by Ethereum is to realize decentralized automatic execution through program

the account called "smart contract account" will only be executed according to the code. This technology has a wide range of applications, including insurance, equity, trust and so on. It can be said that this technology can be applied to all activities that need trust

Sixth, the significance of Ethereum: it represents the blockchain 2.0 era. After the glorious period of 2017, now, in the face of bear market, some ICO projects are worried about being tired by the bear market and cash out one after another, leading to a sharp drop in the price of Ethereum. V God, the founder of Ethereum, is also deeply involved in all kinds of rumors. There are often rumors that he is going to quit Ethereum and he is running away

However, Ethereum is indeed a leap forward in blockchain technology, which represents the era of blockchain

2.0. If bitcoin represents the era of blockchain 1.0, it provides new ideas and new methods for value transfer; Then, the blockchain 2.0 era represented by Ethereum makes the commercial application of blockchain possible

4. Eth rose by more than 1.00% in 5 minutes | chain finance
August 3, 2019 - according to the data of hot coin global station, ETH / usdt fluctuated sharply in 5 minutes, rising by more than 1.00% to 1.03%. The current quotation is 223.10 US dollars, the market fluctuates greatly, please pay attention to risk control.

5. 1. It's normal for bitcoin to plummet and soar in one day and ten years< p> First of all, e to the impact of the epidemic, bitcoin's market is a bit strange and incomprehensible. You know, bitcoin has been around us $9000, and it has not fallen or risen very much, but to everyone's surprise, the price of bitcoin soared by US $10000 on June 2, which shocked many small partners

secondly, even though little friends can't figure out what bitcoin is like, after 7 p.m. the price of bitcoin once soared to $10429 , a good bull market means a sense of vision. Therefore, many small partners believe that the bull market of bitcoin is really coming, and they can't help but start one after another for fear that they will miss this opportunity to make money

then, just an hour after 7 o'clock, the company burst its position by more than $7 million, equivalent to more than $4410 in RMB. On the same day, more than 36000 small partners frantically snapped up bitcoin, setting a record of more than $7 trillion in 24 hours, equivalent to about $5 billion in RMB

finally, just when my little friends were happy to catch the last bus of the bull market, in the last 20 minutes on June 2, bitcoin fell from $10147 to $797 in six minutes , which was more exciting than taking a roller coaster. A proper coin circle, a day, a decade on earth

How do you feel about it< p> 1. The reason why bitcoin has risen so miraculously is once in a century, but its rise is reasonable. We need to know that because of the impact of the epidemic in the US economy, everything is possible

2. For coin friends, whether they are novices or veteran, it is the best choice to choose to wait and see under such circumstances< otherwise, it's not making money, it's giving money

6. Now playing digital currency is basically a game of fighting silly. If you're lucky enough to earn a dish money, if you're not lucky enough to enter the market, you'll be in a mess. Digital currency is essentially worthless. Unless you give it away for nothing, I'll sell it for cash immediately. It really has no real value. It's 10000 yuan today and 10 yuan tomorrow. It's just a money laundering tool for big dealers

7.

On April 18, bitcoin, which rose 755% in the past year, fell 17% in the past 24 hours to below $52000. For "in the end, what makes the continuous rise of more than a year of bitcoin instant collapse?" According to market news, the US Treasury Department accused several financial institutions of using cryptocurrency to launder money

the news comes from the twitter account @ fxhhedgers. Minutes after the tweet, the cryptocurrency market began to plummet. Ethereum plummeted 20%, coin an plummeted 17%, reborn plummeted 26%, Dog Coin plummeted 19%, Wright coin plummeted 28%, wave field plummeted 25%, and grapefruit coin plummeted 29%

according to the cointegraph, according to the data of the capital market laboratory and the documents on the coinbase investor relations website, the CEO of coinbase sold the company's shares and cashed out 290 million US dollars, while the insiders cashed out more than 4.6 billion US dollars

{rrrrrrr}

extended information:

bitcoin price will continue to plummet

some experts said frankly that from the reality, virtual currency including bitcoin does not have the function of currency trading in financial settlement systems of various countries. Virtual currency has the property of financial derivatives, and its price trend is also affected by many factors. Sudden regulatory trends, news and public opinion, and major technological changes may make its trading price fluctuate significantly

In addition to the above reasons, another reason is the excessive concentration of virtual currency holders. Virtual currency trading is mainly carried out through the third party, namely the virtual currency exchange, and the trading platform becomes the largest holder, which also makes it possible for the makers to form a group and control the currency trading price

8.

On April 18, 2021, the global virtual money market plummeted, and the cryptocurrency market experienced the most serious slump in history. On a 24-hour basis, bitcoin has plummeted by more than 16%, Ethereum has plummeted by nearly 20%, coin an has plummeted by 17%, and reborn has fallen by 26%. Within one day, more than 620000 people were liquidated, and the amount of liquidation exceeded US $5579 million. Brian bull, CEO of coinbase, a virtual currency exchange; Armstrong sold $290 million of the company's shares, bringing the total market value of its insiders to more than $4.6 billion. In addition, alexia & middot, the chief financial officer of coinbase; Haas cashed out about $99.32 million at $388.73

it is reported that the ability of cloud computing is to split the mining machine into independent units. The mine provides mining machine computing power leasing services. Investors only need to purchase the calculation contract to & lt; Cloud mining;, Get the corresponding virtual currency. On several cloud computing platforms, it is found that the rate of return declared by each platform is not low, and some annual rates of return even exceed 100%. At the same time, cloud computing capacity is also facing huge risks. In the absence of third-party guarantee and supervision, cloud computing capacity sometimes faces huge risks
