Ethereum energy coin is not MLM

Ethereum is an open source public blockchain platform with smart contract function. Ethereum provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum

in 2013, vitalik buterin, 19, first mentioned the idea of Ethereum in a book entitled "Ethereum white paper: next generation intelligent connection and decentralized application platform". Then, in 2014, the algorithm and protocol of Ethernet coin were officially implemented, and $150 million was raised. The system itself was finally completed on July 30, 2015

as the representative of blockchain 2.0, the mainstream currency Ethernet is regarded as the wind vane of crypto digital currency market. However, over the past week, the price of ether currency has continued to fall. On August 14, 2018, the ethereal currency plummeted by 20%, reaching a record low of $257 this year. Compared with this year's peak of $1295, the price of Ethernet currency has shrunk by more than 80%. Affected by this, on August 15, 2018, none of the top ten mainstream currencies in the digital money market was spared, falling across the board, with a number of single day declines exceeding 10%

extended data

Ethereum started planning almost in 2013, and started to implement the project in 2015. Before that, there were many digital currencies imitating bitcoin in the market, and they made various modifications on the basis of bitcoin code. In this way, it is very difficult to develop a new blockchain application, to re deploy a new chain, and then to develop an application on this chain. Using a consensus mechanism of pow alone is a huge maintenance workload. It's like developing an app on a mobile phone and developing the Android system together

after Ethereum comes out, it is equivalent to the underlying operating system of the blockchain. On Ethereum, it is very convenient to develop various dapps without considering the underlying development, and it can also share the computing power and storage of Ethereum. For programmers, the threshold of blockchain development is lowered instantly. The emergence of Ethereum has played a very important role in the development and popularization of blockchain applications. That's why Ethereum is called blockchain 2.0

2.

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

3. I'm 19 years old. Because of evil Ying, I left society before I graated from high school. I have about four years of hand Ying history. When I was in primary school, I came into contact with evil Ying
when I was almost ten years old, I mixed with some bad people in the village, because they often watched HSE movies. After mixing with them, I was deeply involved and couldn't extricate myself! Since then, I've been thinking all day about how to see HSE movies So, birds of a feather flock together. I remember watching HSE movies with DVD player at that time, but I didn't have one at home. Because of the young age at that time and the HSE film will stimulate people's desire, the more people want to see, the more empty they see! I went to other people's house secretly, locked his room inside and peeped. I saw zhengle. I was found by the owner of this house. He was a very abusive old man, and his son was only at home when he went out. As a result, he was always abusing, abusing badly, and talking about things everywhere. It's the kind of swearing that makes many villagers have a bad impression on me. So that's the truth. HSE movies are really harmful! I guess the reason why he found me was that God reminded me that I would repent when he found me. But at that time, there was no such special platform to understand the harm of evil Ying and the knowledge of abstinence. Even when I was young, I was still stubborn and did not repent
then I went around to find people to borrow DVD players, and HSE movies were also obtained by all means. With all these, I continued to watch HSE movies. At that time, I was really possessed. I read a lot of them, but I couldn't count them. Soon, the result of evil Ying came. When I urinated, my urine began to fork very seriously. All the students who went to the toilet thought I was very strange and laughed at me. Studies also because of the enchanted heart is shelved, by evil Ying entangled people have no heart to learn
when I was 11 years old, because the primary school in the village closed down at that time and I had to go to another school to study, so I had to live in a boarding house (sleeping in the school, I couldn't go home), and many people were crowded in a dormitory. One morning, I woke up and found that I had wet my bed. But I knew clearly that it wasn't me. It was a classmate who was sleeping next to me. He didn't dare to go to the toilet at night, so he peed on my bed. He didn't care about my consequences, so he peed on my bed. Isn't this the result of evil Ying According to my mother, I was very good when I was a child. I never wet my bed. Before that, I had no history of wetting my bed). Now this kind of thing suddenly appears. Isn't it the result of evil Ying? When people in the dormitory wake up, they find my bed wet and smelling of urine. Many people begin to say that I wet the bed. The news quickly spread in the school. Students hate me when they see me. They don't play with me. They look at me with disdain. Many people deliberately stay away from me and laugh at me! I was only 11 years old at that time, and it was a great blow to me at that time! Because of evil Ying, I have to suffer physical and mental devastation, I have to spend the remaining two years of primary school in the cold of my classmates. So this experience brought me not only a spiritual blow, but also a psychological shadow< In the twinkling of an eye, I graated from primary school. At the age of 13, I went to junior high school
confused by evil Ying, I haven't repented yet. I continue to watch HSE movies, and I'm still thinking all day long. Soon, the result of evil Ying came again. After watching a lot of HSE movies, I became impetuous and looked down upon people, believing that "Laozi is the best in the world". So, it shows a very Diao appearance, just in junior high school offended a lot of students! In the class with the English teacher, also make her angry cry, even want to fight with her impulse. Therefore, I was punished by the head teacher, students look down on again! How evil Ying destroys people's body and mind, makes people not like people, and makes people have no mind to study
before I got in touch with evil Ying at all, my learning ability and performance were good, and I was often praised directly by the teacher in the class. Because of evil Ying, I became more and more ignorant and didn't want to study! Later, when I went to junior high school, I became more and more irritable. Even the teachers dare to work against me. Can I study well in this way? Therefore, my academic performance plummeted and became the countdown in the class
evil Ying can also lead to mental decline, forgetfulness, and often saying wrong things. Once, because he said a word without any cover, he offended his classmates. Originally, he had a delicate relationship with many people in the class, which deepened the contradiction. The long-standing resentment finally broke out, and several students beat me up. I haven't realized that being beaten by them this time is just the beginning
next, most of the students in the class looked down on me and pushed me. Even a woman who had offended me before dared to bully me. A few gangsters in the class often beat me and beat me. Evil Ying made me very cowardly and timid. I didn't dare to fight back and let them bully me. I just lived in hell There are many aspects of suffering, which are not detailed here. In a word, evil Ying is very harmful. I hope you will stop being stubborn, wake up quickly, and do good and evil together)
I often wonder if I had done a lot of bad things in my last life before I had to accept such innumerable mental and physical devastation. Until now, I have come into contact with knowledge and traditional culture, I know that everything is the result of evil Ying. When retribution comes, it's not up to you at all

in this way, from the first semester of junior high school to the last semester of junior high school, I have been living in dire straits, bullied by my classmates every day
in fact, one night in the third year of junior high school, I learned the shameful hand Ying
at that time, I was about to go to the toilet, and suddenly I got excited and erect. As a result, I learned how to hold my hands, and since then I have embarked on the road of holding my hands. At that time, I had a mobile phone, so I used it to find many HSE novels, and then I went to the toilet to do it. It's not a human thing! After learning how to do it by hand, I became even more infatuated with HSE. I read both HSE movies and novels. After watching them, I inlged my desire and let it out with my hands. This makes my eyesight serious decline, originally eyes than the same age people, and glittering I, even myopia! What I see is fuzzy, I have no intention to study, and I look at too many HSE things, so I am nearsighted, which is even more contrary to my study
I'm crazy about Ying. I was crazy four or five times a day when I was close to collapse. At least, you can do it in two or three days. This makes me tired when I urinate. I don't have the strength to urinate far away. Pudenda itches from time to time, which is the result of hand Ying
I remember that before hand Ying, my face and body were very clean, and I never had acne. After hand Ying, I had a lot of acne on my face and body, and it was very difficult to eliminate it. Moreover, these acne were itchy, and they often bled as soon as I grasped them, and they lasted for a long time, but now they are not good
evil also affects my life and my family. Before evil Ying, I was very filial, and sometimes I would share my mother's housework. I didn't want her to work so hard, and I was very filial, obedient, and would not resist her! But infected with evil Ying, especially after hand Ying, all this has changed. I often quarrel with my sister, fight and make a fuss! And every new year's festival can not be a happy life, because infected with evil Ying, I become small bellied, especially care, no masculinity! Parents see very sad, mother often tears in front of us to ecate us
the more I am harmed by evil Ying, the more I become unfilial to my mother. I have a hot temper and have no tolerance or filial piety at all. I always contradict my mother. I often scold her when she says a word. Clearly every time my mother is for my good, I also dislike her wordy, told her not to nag, hurt her very seriously
it is said that filial piety is the first of all virtues, and Ying is the first of all evils. Those who commit evils are both unfilial and unfilial, which is very harmful to their own good fortune! I hope you can get rid of evil as soon as possible and show filial piety to your parents. Increase your blessings

with the end of three years of primary school and three years of junior high school, I have been in contact with evil for six years and hand for one year
this year, I was admitted to an ordinary high school. Because I had a lot of evil habits before, I was full of evil thoughts. When I went to high school, I continued to be evil
because high school is a new beginning. Bad people can get better and good people will get worse. It depends on what kind of people you want to be!, I began to fall in love, in addition to bubble girls, is to play on the Internet mobile phone, no mind to learn. At the beginning of school, I was attracted to one, but even if I had a girlfriend, I still couldn't get rid of the bad habit of hand Ying and continued to do it. The end is not long to break up, maybe evil Ying let me become not sunshine, now girls like sunshine boy

in the whole high school, I dated several girlfriends, among them, because these girlfriends fought with others for many times, they were also severely punished by the school, and finally they were expelled from the school
after entering the society, although evil Ying is not as frequent as before, it has not been completely given up. Until... One morning in May this year, I suddenly saw a post from louwaishui2, the bar owner of SY sequelae treatment bar, called: 20 common sequelae of SY
I began to believe why I had encountered all kinds of problems before! So I began to decide to get rid of evil Ying, but e to lack of concentration, I cracked it again after a spermatorrhea, but I still continue to pay attention to the treatment of SY sequelae. Look at the article

until August 11, I learned from the bitter experience and didn't want to be willing to degenerate again, so I made up my mind to get rid of evil Ying. It's full moon today! Ha ha
next, I'd like to share my experience and experience of abstaining from se:
1. In the process of abstaining from evil, you should use less Internet, because the current network pollution is very serious, and any website has some naked women to sece you! It's easy for people with insufficient concentration to think more, and they will change into Yiying. Even more serious, they will break the precepts, and Yiying is very sad! Therefore, we should use less Internet, help friends, encourage friends, and do good deeds to get rid of evil
2. Learn more good knowledge, such as traditional culture. If you don't understand it, the nearest good knowledge is the exquisite post in SY sequela treatment bar. It's really beneficial to read more and implement more
3. If you are in the habit of Yiying, you should stop Yiying immediately and recite the holy name of "Amitabha Buddha" in your mouth to relieve Yiying thought.
4. If you have conditions, you should go to sleep before 10 o'clock and wake up the next day. Don't fall in love with bed, it's easy to Yiying
5. Be filial to your parents. Respect your parents at home, why burn incense far away. This shows that the blessing of filial piety to parents will be great, and heaven will protect it
6. In the early stage of abstinence, some people may have spermatorrhea, and the serious one may be frequent. At this time, we should be more vigilant to prevent breaking the precepts. We'd better go to the bar immediately to read the quality post. We should always keep the causal relationship in mind. In addition, we should think about whether we have made up our mind to give up at the beginning, and how can we break it now

4. Because minors do not have full capacity for civil conct. In China, minors are citizens under 18 years old; In other countries, minors are defined in different age ranges. In Japan, for example, minors are citizens under the age of 20. But in the United States, minors are citizens under the age of 16. It is an important standard to judge whether a person is a minor and whether he has full capacity for civil conct
in bitcoin transactions, you need to open a bitcoin account and bind the bank card for transactions. Minors do not have full capacity for civil conct, so bitcoin trading platform does not allow minors to trade. This is a kind of protection for minors.

5. Go to the right side of belos

6. In philology, Rida said: & quot; If philology is possible, its prerequisite is the deconstruction of logocentrism; So what is logocentrism
logocentrism is another name of Western metaphysics, which is Derrida's general ruling on western philosophy by inheriting Heidegger's ideas. As the name suggests, logocentrism is a structure centered on logos, so we should first understand & quot; Logos & quot;
& quot; Logos & quot; From ancient Greek, for λ In the first volume of the history of Greek philosophy, gersley, a famous historian of philosophy, analyzed in detail the usage of the word "oyos" in philosophy, literature, history and other documents before the fifth century B.C., and summed up ten meanings: (1) anything spoken or written 2) Things mentioned and related to value, such as evaluation and reputation 3) The inner consideration of the soul, such as thought and reasoning 4) Develop from what is said or written to cause, reason or argument 5) And & quot; Empty talk& quot; Excuse & quot; On the contrary, & quot; The real logos & quot; It is the truth of things 6) Scale, propriety 7) Correspondence, proportion 8) General principle or rule, which is a relatively late usage 9) The ability of reason, such as the difference between man and animals, is that man has logos 10) Definition or formula to express the essence of things.
later generations mainly from & quot; Rationality& quot; Truth& quot; Law & quot; Even & quot; Logic & quot; To grasp & quot; Logos & quot; In Heidegger's being and time, this meaning is not groundless, but it is not its original meaning; Logos & quot; Far away from the basis of existentialism, & quot; Logos is experienced as a ready-made thing and interpreted as a ready-made thing; Similarly, the existential shown by logos also has the meaning of being; Therefore, he wants to put & quot; Logos & quot; From & quot; Logic & quot; In his opinion, he thought that "the first is to liberate and restore its original meaning"; Logos & quot; The original meaning is & quot; Talk & quot; Or & quot; Speaking & quot;, Its verb form is legein and its root is 1eg. The basic meaning of 1eg is & quot; Talk & quot Speech is the basic link of human being's Dasein, which forms the whole meaning of Dasein. It links human being's Dasein as a whole in the way of articulation; Heidegger's later period (from the introction to metaphysics in the transitional period) was not satisfied with the analysis of logos as & quot; Talk & quot;, Therefore, it continues to trace its origin, and holds that its original meaning is & quot; Aggregation & quot;, Gathering brings the miscellaneous and mutually exclusive things into the presence. Speech is also a kind of gathering, which makes all things gather into one and show up; Logos & quot; It is not only the omnipresent operation of being, but also the omnipresent operation of language; Aggregation & quot; To explain & quot; Logos & quot; And use & quot; Talk & quot; Explanation & quot; Logos & quot; Although there are differences between existentialism and ontology, they do not change the two core meanings, that is, to refer to & quot; at the same time; Speech & quot The speech of Dasein or being) and & quot; Presence & quot;, In & quot; Logos & quot; Derrida agrees with Heidegger's research that the pursuit of logos is the pursuit of all presence through speech; However, Derrida believes that & quot; Logos & quot; No matter it is in the normal sense & quot; Rationality & quot; Or & quot; Logic & quot; Or Heidegger insisted successively & quot; Talk & quot; And & quot; Aggregation & quot; In all kinds of metaphysical systems, there is always an unchanging presence as the center of its construction system. Derrida has a good summary of this in the opening of structure, symbol and game in the discourse of Human Sciences: there is a desire for center throughout the history of metaphysics, Different centers organize different structures; The history of the whole concept of structure must be regarded as a series of activities in which the center replaces the center, just like a chain of centers. The center obtains different forms and names in a way of successive emergence and mutual coordination. The history of metaphysics, like the whole history of the west, is the history of these metaphors and metonymies, It can be proved that all these names related to the basis, principle or center indicate an unchanging presence -- Eidos [essence], arche [origin], telos [purpose], Energia [energy], ousia [presence], existence [existence], substance [entity], Suiet [subject], Aletheia [Truth], Transcendentalite, conscience, Dieu, homine and so on; The historical manifestations of these presence are as follows: & quot; The presence of things as Eidos facing eyes, as entity / essence / existence, as temporal presence of present or moving point, as self presence of thinking, consciousness and subjectivity, as common presence of self and others; Derrida's philosophy is just a response to these various modes of presence. He re grasps logos from the perspective of signifying activity, that is, Heidegger's interpretation of logos from the perspective of ontology; Presence & quot; Interpretation is examined at the linguistic level (this is mainly influenced by Saussure, later on in detail): the so-called presence means that the signified is separated from the signifier. In the movement of signs, the signifier is originally indivisible, but metaphysics can make the signifier self erase and make the signified appear, and further regard the signified as the unchanging center and the basis of determination, In order to construct metaphysical edifice, Derrida called it & quot; A priori reference & quot According to Derrida, Heidegger's & quot; Logos & quot; Heidegger liberated language from logic, but constrained language in the presence of logos. Therefore, Derrida wanted to liberate language from logos (no matter what kind of logos it is) and classify it as the game's & quot; Words & quot In Derrida's opinion, logocentrism contains two rather contradictory views: first, it is a sound centered concept, namely phonocentrism. In the phenomenon of expressing meaning with symbols, the medium of sound is superior to that of words. Sound is internal and closest to meaning, while words are external, It can only approach meaning through sound circuitously, which is an ideological tradition based on Western phonetic characters. Secondly, in the activity of care, the sound must be hidden and self erased, so that the meaning can be completely and directly present. This is what Derrida called & quot; Metaphysics of presence & quot In this regard, sound centralism is attached to logos centralism, which serves for logos centralism. The only reason for its existence is to let logos lose its superiority when it is present

7. Watch maintenance in summer
the climate is hot and humid in summer. When people sweat in hot weather, the watch may leave green or black marks on the wrist when it encounters sweat. Due to the different pH value in sweat, the degree of clock erosion is also different. Therefore, it is an important issue for watch lovers to take the initiative to maintain their watches
watch maintenance in summer
the reason why the watch turns green with sweat is that the watch factory adopts gold-plated copper-clad plating which is easy and beautiful in color, but if the gold-plated technology is not handled properly, it will cause the watch oxidation. Nowadays, PVD stainless steel plating technique is widely used in gold plating of watches and clocks, so it is rarely found. Therefore, it is recommended to buy stainless steel or K-gold materials. As for the problem of wrist blackening when wearing a watch, it is directly related to poor air quality and st stuck in the watch strap for a long time. In this case, it's best to give it to a professional watch shop for cleaning. You should also pay attention to the cleaning of the watch when you wear it on weekdays.
