区块链老雷,董进 区块链

区块链老雷和董进是当下热门的区块链技术专家，他们深入研究区块链技术，并且发表了许多关于区块链技术的文章和论文。今天，我们将介绍他们提出的三个关键词：区块链技术、去中心化和智能合约。

区块链技术

区块链技术是一种分布式数据库技术，它将数据分布存储在多个节点上，每个节点都是一个独立的计算机系统，它们之间通过网络连接，每个节点都可以获取所有数据。区块链技术的特点是去中心化，它的数据不受任何中心化机构的控制，数据的安全性和可靠性得到了很大的保障。区块链技术也可以用于记录财务信息，如货币交易、股票交易等，可以更有效地记录财务信息，减少记录错误的可能性。

去中心化

去中心化是区块链技术的一个重要特点，它指的是没有中心化机构控制数据的存储和使用，也就是说，数据存储和使用的权力完全在用户自己手中。去中心化的优势在于，用户可以更加安全地存储和使用数据，因为他们不必担心数据泄露给中心化机构，也不必担心自己的数据被篡改。去中心化的缺点在于，由于没有中心化机构控制数据，数据的安全性和可靠性可能受到影响。

智能合约

智能合约是区块链技术的一种重要应用，它指的是基于区块链技术的一种自动执行的合约。智能合约可以用于自动执行合同，自动执行财务交易，自动审核用户信息等。智能合约的优势在于，它可以自动执行合同，减少人工审核的步骤，提高效率；另外，智能合约也可以用于保护用户的数据安全，因为它可以自动审核用户的信息，从而防止数据泄露和篡改。

以上就是区块链老雷和董进提出的三个关键词：区块链技术、去中心化和智能合约的介绍，他们的研究为我们更深入地了解区块链技术提供了重要的参考。

『一』 floating loss exceeded 300 million yuan! Meitu's big bet on cryptocurrency "failed"

As the price of cryptocurrency fell, Meitu, which had bought at a high point, tasted the "bitter fruit". Meitu recently announced that it has confirmed impairment losses of approximately 311 million yuan (RMB, the same below) in Ethereum and Bitcoin purchases, resulting in a net loss of 274.9 million yuan to 349.9 million yuan in the first half of the year.

Analysts pointed out that Meitu’s allocation of Bitcoin and Ethereum cannot improve its technology and application level in the domestic blockchain field, and may be hoping to use the rise in cryptocurrency prices to boost its performance. Performance. However, because Meitu purchased Bitcoin at a relatively high price, and the cryptocurrency market is extremely volatile, it is unclear whether it will bring benefits to Meitu in the future.

Recently, Meitu, a Hong Kong-listed company, issued inside information and a profit warning announcement. As of June 30, 2022, Meitu may record a net loss of approximately 274.9 million yuan to 349.9 million yuan. Compared with The net loss of approximately 137.7 million yuan in the same period last year increased by approximately 99.6% to 154.1%. The expected increase in net losses is primarily due to the impairment of purchased cryptocurrencies.

On the evening of March 7, 2021, Meitu issued an announcement stating that the group purchased 15,000 units of Ethereum and 379.1214267 units of Bitcoin in open market transactions on March 5, 2021. The total consideration of these two cryptocurrencies is approximately US$22.1 million and US$17.9 million respectively, totaling US$40 million (approximately RMB 260 million). Subsequently, topics such as "Meitu purchased Bitcoin and Ethereum for US$40 million" and "Chairman of Meitu responded by buying cryptocurrency for US$260 million" became hot searches on Weibo.

More than ten days later, Meitu announced that its wholly-owned subsidiary Miracle Vision purchased a further 16,000 units of Ethereum for a total consideration of approximately US$28.4 million; and purchased 386.08 units of Bitcoin for a total consideration of approximately US$28.4 million. Approximately $21.6 million. Judging from the announcement information, the average transaction prices of Meitu’s purchases of Ethereum and Bitcoin were US$1,775 and US$55,900 respectively.

More than half a month later, Meitu once again announced its purchase of cryptocurrency. Meitu has purchased a total of 31,000 units of Ethereum and approximately 940.89 units of Bitcoin, with corresponding total prices of US$50.5 million and US$49.5 million respectively, totaling US$100 million.

Less than a year and a half after I bought the currency, the value of cryptocurrencies fell rapidly, with Bitcoin falling below the $20,000 mark, which directly led to the decline in Meitu’s performance. Meitu is expected to announce impairment losses of approximately US$18.5 million and approximately US$27.1 million in purchased Ethereum and Bitcoin respectively in its 2022 interim financial report, totaling approximately US$45.6 million, or approximately RMB 311 million.

Allocating cryptocurrency is a "big gamble" for Meitu to boost its performance and stock price. Meitu stated in the announcement that its investment in Ethereum was to prepare for entering the blockchain industry. Investing in Bitcoin is one of Meitu’s asset allocation strategies.

In fact, Meitu, whose transformation has not been smooth, has already tried to get involved in the currency circle. Cai Wensheng, chairman of Meitu, invested in cryptocurrency exchange OKEx in 2014. At the beginning of 2018, Cai Wensheng became the rotating group leader of the "Three O'clock Blockchain Group". Longling Investment, founded by Cai Wensheng, also has a stake in the cryptocurrency exchange FCoin.

Also in early 2018, Meitu launched a blockchain wallet product called Beautychain. Later, Beautychain’s token “BEC” was listed on OKEx, and Meitu was accused of Is the issuer of BEC tokens. In April of the same year, abnormal transactions occurred in BEC tokens that had been online for two months. A hacker used the batch transfer method of the contract to generate unlimited tokens, triggering a wave of selling and the currency price almost reaching zero. Meitu later stated that it “does not and will not issue any digital currency.”

Dong Sheng pointed out that according to Meitu’s statement in the announcement, investing in Bitcoin is only for one of the company’s asset allocation strategies, while investing in Ethereum is for Meitu to enter the blockchain industry. Preparations made. However, in the domestic market environment, allocating Bitcoin and Ethereum does not mean that Meitu is increasing investment in blockchain. The currency circle and the chain circle have always been distinct in China. Meitu's allocation of Bitcoin and Ethereum cannot improve its technology and application level in the domestic blockchain field.

Long-term losses have also caused Meitu’s stock price to collapse and its market value to plummet. Meitu’s stock price once exceeded HK$23 in March, the second year after its listing (2017), but then fell. From the second half of 2019 to 2020, it hovered around HK$1 for a long time. It only returned to HK$2 in February 2021, and has recently hovered around HK$1. As of the close of trading on July 5, Meitu closed at HK$0.93, which was the same as the closing price of the previous trading day. The stock price fell 10.58% the previous day.

He mentioned that the most important thing is people. He emphasized the development of the community and the media. The power of people who can connect with those at the bottom will have a future. These are all worth thinking about. As for the blockchain, it is true that there are no real applications yet, but whether it is Bihu, IveryOne, primas, ONO, or EOS, they are all teams that are working hard to do things. It is hard to say whether they can succeed, but if To say that they worked so hard just to cut leeks, Mingchun is indeed unjust. Think about the Internet in 2009. It’s the same as when we talk about blockchain today.

This model has very few loopholes and is not perfect, but it can be said to be perfect. There is no such thing as pie in the sky. If you don't work, it means you are leaving money in the bank.

『Lu』Which blockchain solution company is better

Blockchain is a shared distributed database technology. Although the one-sentence introduction to blockchain is worded differently in different reports, the following four technical features are consistent: Decentralization, trustlessness, collective maintenance, reliable database. Among the many blockchain technology companies currently, the blockchain technology development solution provided by Yingtang Zhongchuang is a good example of the application of blockchain technology.

『撒』 Blockchain is very popular at present. What are the powerful large companies in China doing it?

IBM, Microsoft, Oracle, Ai Senzhe, Tencent, Alibaba, JD.com, Everything has been done on the Internet, including many large banks such as Ping An Bank, which have also launched their own blockchain solution platforms or solutions. But it should be added that large companies do not mean strong technical strength, because blockchain is still in the conceptual hot stage around the world. It is very likely that there will be unicorn blockchain companies in the future, such as EOS in foreign countries, Hive Chain of domestic Panrong Technology, etc. The efficiency of TPS and packaging into blocks may be much higher than that of large companies.

『八』Bitcoin is wailing, and the US stock market has fallen into hot searches. What happened to this market?

Last night, a friend mentioned that Bitcoin fell by 10,000, and the problem came up. , whether it is rising or falling, this is normal. Only when the network cable is unplugged and the exchange cannot log in is it abnormal. This is the favorite trick of the betting platform.

Last weekend, I saw someone say: The currency I bought increased to more than 50,000, and I wanted to sell it. As a result, the website could not be logged in, and I watched it fall in vain. It's a pity that I haven't done this myself. My stock software doesn't support me to see this kind of trend, and I don't understand the ecology of this market, so I don't dare to talk nonsense. I just posted two articles about making hundreds of dollars. Wan's article, I hope my friends will invest wisely and choose the right time to invest.

Now I will talk about Bitcoin as an outsider. In fact, no matter what currency it is, no matter what trading variety it is, as long as it is listed for trading, it follows one principle: price discovery. In other words, if bullish people think it is going to rise, then they buy it! Bearish people think it is going to fall, so they sell. The two parties have reached a transaction intention, the sale is successful, and the price is set there.

If some people continue to be bullish, and the buying orders are greater than the selling orders, it will continue to rise. When it continues to rise, some people feel that it has risen to their expectations, and they are eager to cash in their profits. Such a sale appears. When its buying orders can outweigh the selling orders, it still goes up! When there are more and more selling orders, the buying orders cannot bear the selling pressure, and it falls. This is the price movement, price discovery, that promotes transactions.

From my perspective, at the end of 2018, when Bitcoin was still worth $8,000, someone held it. Now that it is over $50,000, he must be unable to hold on and want to cash out. Profits were made. This is what I often say: if it rises too much, it will inevitably fall if it rises too much. This is also the inevitable law of price movement. I am a technical analyst. I can only explain it from the law of price movement. Other fields are not within the scope of my research and will not be involved.

Let me talk about the fact that the US stock market fell into hot searches. For example, I analyzed Tesla last time.Its price used to be $75, but when it rose to $800, a tenfold profit, someone must have made huge profits and wanted to cash in. U.S. stocks rose sharply from last year to this year. Naturally, many stocks have also risen sharply and become hot searches. When someone wants to cash in their profits, it will naturally become a hot search topic.

Therefore, I want to say to my friends: If you focus on the principles of price discovery and the laws of price movement, you will be able to remain calm. You don’t need to know what’s going on. You only need to know: What should I do? ! Only in this way can we respond well.

Recently, a very unusual signal has appeared in the financial market - the yield on the US ten-year Treasury bond continues to rise.

The ten-year Treasury bond yield in the United States is a benchmark for the global financial market. Although the ten-year Treasury bond yield in the United States has begun to rise since the end of July last year, it has been at a relatively low level. Location. Many international institutions have a psychological critical point for government bond yields. That is to say, when the yield reaches above 1.5%, major institutions become wary of inflation in the financial market. This excessive inflation may cause the Federal Reserve to be forced to raise interest rates ahead of schedule. With big funds expecting such an interest rate hike, coupled with the recent surge in global commodities and Bitcoin, a large amount of profit-making funds will naturally flee. Even backhand shorting.

A key point for Bitcoin’s skyrocketing rise is that the liquidity of market funds must be sufficient. When the government bond yield reaches 1.5%, the market actually tightens liquidity in disguise, so it is difficult for Bitcoin to have enough funds to continue its upward trend. Not only Bitcoin, but also the top technology stocks in the United States have fallen sharply. More and more investors are beginning to reflect on whether the future growth potential of these large technology companies is worthy of the current stock price, and whether the bubble has gone too far.

Although the market rises and falls, what goes up must come down, and what goes down must come up. But the logic behind it requires us to "explore", do what we can understand, and make money that we understand, so that we will not lose control and chase the rise and kill the fall.

For me, who has experienced the explosion of Bitcoin, this kind of plummeting has become normal [face covering]. In the past six months, the transaction price of Bitcoin has soared from US$10,000 to US$58,000, an increase of 480%. This surge was caused by the Federal Reserve's massive release of water under the influence of the epidemic, and a large amount of funds from international investment institutions and financial giants poured into the digital currency market. This directly pushed up the price of Bitcoin, and other small currencies and mainstream currencies also followed suit. Some small currencies even increased more than Bitcoin. For example, OKB soared from a minimum of 4 US dollars to 23.8 US dollars.

1. Characteristics of the digital currency trading market: 24 hours a day, 365 days a year; no limit on rise or fall; diversified trading models, including spot trading and futures trading;

< p>

2. There are many institutions and predators controlling the market: numbersThe currency trading market is obviously affected by large institutions. Due to its hidden nature, the market rises and falls beyond ordinary people's imagination. Therefore, governments of all countries do not recognize the legality of its transactions. Therefore, the digital currency trading market is a huge gambling market, and some people have experienced this overnight. Suddenly rich, some people fell back into poverty overnight;

3. As the United States continues to release money, the global economy has come to a standstill due to the epidemic, and signs of a bubble in the U.S. stock market are emerging. , the hot money in the market couldn't bear the restlessness in their hearts, and began to become active, waiting for opportunities;

Up, up, down, down, down, up, up, not just up. A market that does not fall. The plunge is the release of risk. Of course, it cannot be ruled out that this is a precursor to the next round of global economic crisis.

Bitcoin is a value that has been speculated. It lacks the value of a fair circulating currency in society and is just a string of virtual numbers. It deviates from the market rules of circulating currency. That's why there have been recent sharp fluctuations in Bitcoin. 490,000 people liquidated their positions across the network within 24 hours. The largest liquidation was worth more than 20 million US dollars, and more than 4.6 billion US dollars of funds were "wiped into ashes."

Please note that things that actually exist will not be "disappeared" out of thin air. The real funds invested in the currency circle just flow from one person's pocket to another person's pocket. . What "disintegrates" is just the bubbles that are blown up. Since it is a bubble, it will burst one day.

Judging from historical experience, a bubble cycle can be divided into five stages: gestation, prosperity, excitement, dilemma, and decline. Before the bubble reaches its highest point, everyone is a bubble-blower, and of course there are also manipulators behind it. Everyone who participated saw rising hopes from the ever-expanding bubble. This kind of unearned benefits that exceeded expectations caused those who tasted the sweetness to lose themselves and get deeply involved in it, and also tempted those around them.

Some people have only seen the first half of the money-making period, while some people still want to escape even though they know that staring into the abyss is likely to be swallowed by the abyss. In the end, only a very small number of people were able to escape unscathed, and traders had already sold out and taken away most of the funds when they were close to the high position. The vast majority of people spent all their money to collect money to buy lessons and became the ultimate successors.

It can be seen that people who invest in Bitcoin are no different from gamblers. This is not to deny those who hold a small amount of Bitcoin, such as diamonds, antiques, calligraphy and paintings, game skins, etc. Everyone has their own plot, and when you want to sell them, they can still be exchanged for potential value. But if you risk your life and fortune, you may become the ultimate taker. No gambler quits immediately after winning. He always hopes to win more later. In fact, it always backfires. Bitcoin is not a store of value, and its price fluctuates greatly. People who speculate in Bitcoin may become rich overnight, or they may become pauper overnight.

What exactly is Bitcoin?

Bitcoin is actuallyMaintain the reward mechanism of the blockchain accounting system. Without Bitcoin as a reward, no organization, institution, or individual would be willing to participate in such a thing as accounting. The purpose of miners mining is to earn Bitcoins, and for the entire blockchain accounting system, the more people involved in mining, the more people involved in confirming ledger data, and the more secure the block data will be.

In the beginning, 50 Bitcoins were awarded each time, and the rewards were halved every 4 years:

From 2009 to 2012, 50 BTC were awarded each time;

From 2013 to 2016, each reward will be 25btc;

From 2017 to 2020, each reward will be 12.5btc;

According to this plan, by around 2140, the reward will becomes 0, and the total number of Bitcoins is approximately 21 million. The scarcity attribute of Bitcoin determines that it will have room for appreciation, and many people attach great importance to the prospect of hype and bubble-blowing. Much like the supreme QQ account in the past, when WeChat appeared, the virtual value of the QQ account suddenly disappeared.

There are so many nodes in the blockchain that keep accounts, so whose one should prevail? Satoshi Nakamoto thought of this: Each node in the blockchain competes for the right to keep accounts through "mining".

After the mined mines pass verification, they are packaged together with the ledger and broadcast to the blockchain, thus completing the accounting process.

"Mining" is actually using a machine to solve a mathematical problem (don't try to use human calculations). Whoever calculates the closest result first will have the right to keep accounts, and of course will also get corresponding rewards. The algorithm of Bitcoin mining is to perform two sha256 hash operations on the block header. If the result is less than the difficulty target specified in the block, the mining is successful.

The random number nonce can be tried from 0 to 2 raised to the 32nd power, until the hash result is lower than the difficulty target value. For example, after inputting the guessed value, the first 40 characters of the hash value are all zeros, and The requirement is the first 35 zeros, then it must meet the requirements.

At this time, we will find that there is no difference between Bitcoin and the character skins in our game backpacks. Some skins can be sold on the street, and some skins can be sold for a lot of money if they are resold, but if you play If there are too few people in this game, no matter what kind of skin it is, it will be worthless. The same is true for Bitcoin. It was just stared at by interested people and then hyped up.

Summary

Bitcoin’s wailing is doomed. The "Tulip Bubble" in the Netherlands was the first recorded financial bubble in human history. In the 17th century, Augustus' tulip bulb "futures" eventually evolved into a national craze for speculating on tulips among the Dutch who pursued luxury. In 1637 A "Forever Augustus" tulip cost as much as 6,700 guilders in 1998, which was enough to buy a mansion. At that time, the average annual income of the Dutch was only 150 guilders. The bubble isA sailor on a cargo ship transporting tulip bulbs broke the news. He cooked the bulbs like onions, eventually restoring the original value of tulips, and those who eventually held "futures" became takers. In April 1637, the Dutch government terminated all contracts and banned speculative tulip trading, thus completely bursting this unprecedented economic bubble.

The wheel of history keeps moving forward. There are many similar cases, but people always make the same mistakes again. Isn't this sad? Just like in "A Fang Gong Fu", "Qin people have no time to mourn themselves, and later generations will mourn for them; later generations will mourn without taking note of it, which will also make future generations mourn for future generations again."

The above personal opinion , welcome criticism and correction.

Bitcoin is wailing, which can reflect the popularity of the market. Bitcoin has been rising all the way, and it has already gone crazy. It depends on who will be the last to take over. At present, it seems that the rise has not reached its end, and it can still go crazy for a while. After all, it has been rising all the way, and too many people have become jealous along the way. Now that Musk, the rocket builder, has come to light the fire and promote Bitcoin, everyone must have entered the market in droves again, so if there is a slight fluctuation, there will be too many people. People's interests are harmed. There was inevitably a lot of wailing.

It is normal for U.S. stocks to be trending when they fall. As long as there is a U.S. stock market that falls by more than 2 percent, there will always be news about the plunge to grab attention and attract attention. After all, many media companies are pointing to it. These news make money to survive.

Of course, the U.S. stock market has been rising for too long, and too many people are waiting for the U.S. stock market to crash. They just don’t know if there will be an innocent snowflake after the avalanche comes.

The previous rise in the U.S. stock market was abnormal and not a natural rise. After all, judging from the past, affected by the epidemic, factories shut down production and closed down, a large number of people lost their jobs, and the economy regressed. The stock market should follow the rules and decline. However, the United States is printing money like crazy, allowing the world to share its pressure, and continuing the false prosperity of the stock market. If productivity recovers in the future and can bear the consequences of money printing, then the US stock market can continue to rise. If it cannot bear the consequences, there is a high probability that it will When the bubble bursts, the stock market will have a major correction.

1 There is nothing wrong with this market. A market without volatility is a market with no investment value. There is no market in the world that only rises but never falls or only falls but never rises. People who say that Bitcoin has plummeted have increased tens of thousands of times, and it has been adjusted no less than 100 times more than this time. There is nothing unfounded to worry about.

2 The market is always affected by various news, and the daily rise and fall are also uncertain, because there are too many forces that affect the direction and the power of people's hearts, but this is the ability Opportunities for investors to make money, how can the market allow everyone to make money? Therefore, the investment market must be a market where a few people make money.

3. If you have to ask what’s wrong, you may need to ask hundreds of questions a year, because novice investors will never understand the fluctuations of the market.

4. The ups and downs of U.S. stocks are basically hotly searched several times a month. If they fall too much, they will rise. If they rise too much, they will fall. It’s that simple. If you can't understand this, I suggest you don't participate in any form of investment, because you will definitely lose money.

Over the past weekend, Bitcoin has continued to rise sharply, once exceeding $58,000, setting a record high. However, the digital currency market suddenly changed on Monday, Beijing time, and Bitcoin continued to rise. It fell, falling below the three integer levels of $55,000 to $53,000 in the afternoon, with a 24-hour drop of more than 8%.

In just one day, as many as 370,000 people were liquidated, and about 24.5 billion yuan was wiped out. The currency circle is crying! Countless bull positions were liquidated!

Why did Bitcoin plummet yesterday?

The direct reason is a sentence from the former Chairman of the Federal Reserve.

Aunt Yellen said that Bitcoin is often used for illegal financing and is a highly speculative product. Speaking of Bitcoin as an outsider, in fact, no matter what currency it is, no matter what transaction it is, As long as it is listed for trading, it follows one principle: price discovery. In other words, if bullish people think it is going to rise, then they buy it! Bearish people think it is going to fall, so they sell. The two parties have reached a transaction intention, the sale is successful, and the price is set there. So at its root, it is a question of who will run away first under the background of sufficient liquidity. This is also the reason why Bitcoin started its current boom. The epidemic triggered a global economic malaise, and the United States released a large amount of water to save the economy. Needless to say, Americans themselves are worried about the future of the economy, inflation, and the retention of their wealth. Some investors believe that Bitcoin is an attractive alternative to gold and the US dollar and a perfect "safe haven asset", so many people are chasing Bitcoin in the hope of resisting inflation and preserving the value of their assets. In addition, the increasing holdings of institutions have also attracted investors to blindly follow the investment, including listed companies and fund companies. Tesla also purchased US$1.5 billion in Bitcoin, and even the U.S. government also participated. It is quite understandable that people are eager to invest in safe-haven assets under monetary easing, but yesterday's plunge does not seem to be the case. This round of bubbles is accumulated from the flow, and institutions are aware of this, but everyone wants to be the "first" to escape when they see through it without saying it. Therefore, at the slightest movement, the market will vibrate violently. How did ordinary investors react? Some investors sell in panic. Some investors jumped on the market while it was falling. But more investors are confused and unable to see clearly. These people who enter the battlefield of speculation for the purpose of "hedging" seem to have violated their original intentions. Let’s review the continuous upward trend again. It’s no longer a cheap price.

European Central Bank President Lagarde once said that Bitcoin is not a real currency and is often used for money laundering. It is judged that central banks will not recognize it as a currency soon.Reserve currency. JP Morgan strategists also said that Bitcoin’s liquidity is low, which means that the trading volume of Smile can cause large price fluctuations. Elon Musk also said: A bit high.

The currency circle is changing rapidly. It plummeted last night. Before everyone could understand the market trend, Bitcoin quickly rebounded. How about it being like a roller coaster? When you dive down, you are so scared that you want to jump out of the car. When you get off the car, you find that the car has gone straight into the sky. Therefore, everyone must clearly understand their investment purpose. Is it to pursue risk aversion? Or looking for excitement? Is it to steadily accumulate assets? Or endure the suffering of the plunge? The most miserable people in the currency circle are those "players" who came in late. Most of them have no investment experience. They listen to the advice of "experts" and operate based on their feelings. But you must know that a large number of Bitcoins are concentrated in the hands of a very small number of people. They have control over the price. This also leads to the possibility that ordinary players cannot escape the human weakness of "greed" and lose themselves and money in the sudden rise and fall. .

They are essentially toys controlled by Wall Street capital. Even if they want to speculate Bitcoin to 50,000 or 600,000 US dollars, it is not surprising. Don’t talk about blockchain and the practical value of Bitcoin. It’s useless.

Some time ago, I saw some people making a lot of money, showing off their profits everywhere, and easily making ten times the profit by adding leverage. In the past two days, many people have liquidated their positions and lost everything. Not many people can really hold on to their profits and escape unscathed.

Harvesting capital is ruthless, let alone investment, just a gambler. Bitcoin is not for ordinary people to play with.

There is no market that only goes up but not down. There is no market that only goes down but not up. Monetary policy

This market has always been like this. A small number of people will always make money, and the majority will make money. People lose.

The money you make is the money others lose.

First of all, the fluctuations of Bitcoin are simply too much for the average person’s electrocardiogram. Bitcoin has always been said to have only 21 million, but it can go to many decimal places, which is simply infinite. Transactions can be cut. In essence, Bitcoin is infinite, and most people who enter the market leave just to make profits.

But large institutions control nearly 80% of Bitcoins, how do you play?

Let’s talk about the U.S. stock market. This thing has always been in line with the Federal Reserve’s harvesting of leeks, not only in the United States, but also in the world. As long as the U.S. dollar remains the settlement currency of all countries in the world, the United States will be like a devil and abnormal.

Finally, let’s talk about our big A-shares. China has developed so well in recent years. As a result, when the A-shares in the United States and Hong Kong fell, we fell, and when the United States and Hong Kong rose, we fell. In the past few days, all the previous gains have fallen. Many people say they want to buy the bottom, but they are afraid of buying it halfway up the mountain! This is embarrassing! Now funds can lose 7% a day, which is similar to stocks.

Money in finance is indeed not easy to make.

Borrowing money also depends on the person.
