Ethereum falls below $100

1. Some institutions have predicted that Ethereum will rise to $2500 by the end of the year, but it seems unlikely in the current market. Domain Kingdom's latest Ethereum price is $166, down 16% from yesterday
although the price of Ethereum continues to decline, there are still many investment opportunities. Nowadays, many people invest in Ethereum through virtual currency trading in the realm Kingdom, which is not affected by the rise and fall of prices, but also can invest less money in the shortest time to obtain more income.

2.

There is an essential difference between Ethereum and bitcoin. What is the difference? Bitcoin defines a set of currency system, while Ethereum focuses on building a main chain (which can be understood as a road) to allow a large number of blockchain applications to run on this road

from this point of view, Ethereum's application scenarios are more extensive, which is why we say that Ethereum marks a simple monetary system in the era of blockchain

1.0, and a transformation to other instries and application scenarios in the era of blockchain 2.0

however, there is no perfect thing in the world. Although Ethereum has expanded the application scope of blockchain in all walks of life and improved the speed of transaction processing, it also has some disputes and doubts

first, the solution to the lack of scalability of Ethereum: slicing technology and lightning network

the bottom design of Ethereum, the biggest problem is that Ethereum has only one chain and no side chain, which means that all programs have to run on this chain equally, consuming resources and causing system congestion. Just like last year's very popular Ethereum game "encryption cat", when this game was very popular, it once caused Ethereum network paralysis

to improve the processing capacity, Ethereum proposes two ways: shard and lightning network. Let's introce these two technologies respectively

(1) fragmentation technology

vitalik buterin, founder of Ethereum, believes that the reason why mainstream blockchain networks such as bitcoin process transactions very slowly is that every miner has to process every transaction in the whole network, which is actually very inefficient. The idea of fragmentation technology is: a transaction does not need to be processed by all nodes in the whole network, as long as some nodes (miners) in the network are allowed to process it. Therefore, Ethereum network is divided into many pieces. At the same time, each piece can handle different transactions. In this way, the network performance will be greatly improved

however, the slicing technology is also controversial. As we all know, the important idea of blockchain technology is decentralization. Only when the whole network witnesses (processes) the same transaction can it have the highest authority. The Ethereum slicing technology is similar to the group witness, not all nodes witness together. In this way, it will lose the absolute "decentralization" attribute, and can only achieve the purpose of high performance by sacrificing certain characteristics of decentralization

(2) lightning network

lightning network uses the way of transaction under the chain. What does that mean? It means: when the participants of lightning network transfer money to each other, they do not need to confirm the transaction through the main chain of Ethereum, but create a payment channel between the participants and complete it under the chain

however, lightning network is not separated from the main chain. Before establishing a payment channel, you need to use the assets on the main chain as collateral to generate a balance proof, which indicates that you can transfer the corresponding balance. In the case that both parties of the transaction hold the balance certificate, both parties can make unlimited number of transfers under the chain through the payment channel

only when the off chain transaction is completed and the assets need to be transferred back to the chain, the balance change information of the main chain account will be registered on the Ethereum main chain, and no matter how many transactions occur ring this period, there will be no record on the main chain

another real benefit of lightning network is that it can save the cost of miners for you. At present, when we trade on the main chain of Ethereum, we need to consume gas and pay for miners. Once we move the transaction to the lower chain, we can save this part of the cost

Of course, lightning network is not perfect. When using the lightning network, the assets on the main chain should be used as collateral; And this part of assets as collateral can not be used before the user completes the transaction under the chain. This also determines that lightning trading is only suitable for small transactions

the above is the problem of insufficient scalability of Ethereum, as well as the two main solutions: fragmentation technology and lightning network

Second, there are loopholes in Ethereum's smart contract and the infamous Dao event

Ethereum's smart contract is very powerful, but there are loopholes in any code. The biggest controversy of Ethereum's smart contract lies in the so-called loopholes, that is, security issues. According to relevant research, 34200 (about 3%) of the nearly 1 million smart contracts based on Ethereum contain security vulnerabilities, which will allow hackers to steal eth, freeze assets or delete contracts, such as the infamous Dao incident

(1) what does Dao mean

before introcing the Dao event, let's first introce what Dao is. Dao is the abbreviation of decentralized

autonomous organization, which can be understood as decentralized autonomous organization. From the perspective of Ethereum, Dao is a kind of contract or a combination of contracts on the blockchain, which is used to replace the government's review and complex intermediate proceres, so as to achieve an efficient and decentralized trust system. Therefore, Dao is not a specific organization, that is to say, there can be many Dao, all kinds of Dao

(2) the infamous Dao event

however, when we talk about Dao now, we basically refer to the Dao event, that is, the infamous hacker attack event we just mentioned. As we know, the English word "the" refers to "the Dao event". The Dao event

refers to "the Dao event", because we just said that Dao is not a specific organization, there can be many Dao, all kinds of Dao

in 2016, slock.it, a German company focusing on "smart locks", launched the Dao project on Ethereum in order to realize decentralized physical exchange (such as apartments and ships). Since April 30, 2016, the financing window has been open for 28 days

unexpectedly, this Dao project is very popular. It raised more than US $100 million in just half a month. By the end of the whole financing period, it raised a total of US $150 million. Therefore, it has become the largest crowdfunding project in history. However, it didn't last long. In June, hackers took advantage of the loopholes in the smart contract to successfully transfer more than 3.6 million Ethernet coins and put them into a Dao sub organization, which has the same structure as the Dao. At that time, the price of Ethernet currency fell directly from more than $20 to less than $13

this event shows that there are loopholes in smart contracts, and once the loopholes are exploited by hackers, the consequences will be very serious. This is why many people criticize Ethereum and say that its smart contract is not smart

to solve this problem, many foreign companies begin to provide code audit services in order to solve the vulnerability problem of smart contract. From a technical point of view, some teams are currently testing smart contracts. Most of these teams are led by professors from Harvard, Stanford and Yale, and some of them have obtained investment from leading institutions

in addition to the problems of insufficient expansibility and loopholes in smart contracts, the controversy over Ethereum lies in the POS consensus mechanism it pursues, that is, the proof of equity mechanism. Under the proof of equity mechanism, if anyone holds more money and holds it for a longer time, he will get more "rights" (interests) and have the opportunity to get bookkeeping power, Bookkeeping can also be rewarded. In this way, it is easy to create the oligarchic advantage of "the stronger the stronger"

Another problem is the chaos of ICO. ICO is a common way to raise funds for blockchain projects, which we can understand as pre-sale. The outbreak of ICO projects on Ethereum has caused illegal activities such as fund allocation and money fraud under the banner of ICO, which has caused security risks to social and financial stability

3. After nearly two years of bear market in the currency circle, the currency price of Ethereum has now dropped to more than 900 yuan, and the current downward trend continues. Short Ethereum is now a better trading strategy. At present, digital currency exchanges that can be short, such as coin an, fire coin, bitnet.

4. For indivial investors, the realm kingdom with lower investment threshold is more suitable, because its entry threshold starts from $100, which is very low.

5. The bottom line of Ethereum will never drop to US $20 to US $40 in the short term. All currencies that have experienced private placement will be so involved in the public chain of Ethereum and other smart contracts unless they are directly removed from the shelves. There are still more than 20 days before the end of the year. At present, the possibility is almost zero

Ethereum's short-term performance is still strong, and the $100 psychological barrier has not been broken. Even at the low point of $3650, bitcoin is struggling to maintain at $101. In the future, if bitcoin continues to fall, the effective support point below it will be around $78. However, if the topic says $20 to $40, bitcoin will return to more than $2000, or the targeted counterfeit token is bad. But at present, these two points are not realistic

many investors think that Ethereum and other mainstream currencies are very unlikely to return to zero at present, and there are not many orders in the futures market, so it is not profitable for the main trading to fall down at this time. Even if he has enough empty orders himself, no fish will take the t, and it is difficult to level them all, And the spot price is to follow the futures, Ethereum futures, if there is no intention to fall, the spot will only cross

secondly, even if Ethereum eth really falls to such a level in the future, it is also based on the premise that most of the counterfeit coins are returned to zero or removed from the shelves. Because in a strict sense, Ethereum is the strongest backing of many counterfeit coins. Now, with the reshuffle of the bear market accelerating the process of the demise of counterfeit coins, more and more counterfeit coins are taken off the shelves, which will also affect Ethereum in terms of capital, but it will take a process, which will not be achieved overnight. From the time node, at least it will be next year.

6.

I think the first reason why Ethereum has been setting new records is that it has a lot of capital

the second reason is that many ordinary people have paid attention to virtual currency . These ordinary people have strong purchasing power, and they may have been speculators in stocks or funds before. When they find that the virtual currency is rising well, they will bring a lot of money into the market. The admission of these ordinary people will increase more capital admission, because in the view of capital, these ordinary people are a crop of leeks

the third reason is e to the soaring price of bitcoin, bitcoin is now rising very rapidly, from $20000 a bitcoin in 2020 to $60000 a bitcoin now. It's terrible. For a lot of capital, they can't speculate on bitcoin. Because bitcoin's plate is too big, they have to go back and speculate on Ethereum

first, a large amount of capital has entered the market

at present, the global economy is not very good, there are not many things that can be invested, and the global currencies are devaluing and inflating for a lot of capital, their money will depreciate one day if they hold it in their hands. They need to invest their money. At this time, they find that the virtual currency can keep the value and will not inflate. At this time, there will be a lot of capital, with a lot of money to buy Ethereum. When a lot of people go to buy Ethereum, it is normal for Ethereum prices to rise

7.

The price of Ethereum has exceeded US $3000. The catalysts behind the rise of Ethereum are as follows:

1

2

3. Virtual currency needs a new leader, and Ethereum is selected by the capital

there is an old saying on Wall Street: there is nothing new in the world. What happened in the investment market must have happened before, because the whole financial history has been for hundreds of years. The speculation and investment of virtual currency are similar to stocks, but the risk of virtual currency is greater. The price of Ethereum has exceeded US $3000. The main catalyst behind the rise of Ethereum is the sharp rise of bitcoin and dogcoin. Ethereum, which has always been favored by everyone, has always been in the stage of undervaluation. There is linkage between virtual currencies, and there will be high and low switching. Ethereum has been recognized by market funds as a new virtual currency leader, Funds believe that Ethereum is undervalued and thus driven up by funds, which is the most important catalyst for Ethereum's rise

virtual currency is a kind of high-risk and high-yield investment, which is not recommended by general investors. The risk is too big for everyone< br />
