A. How to make money with blockchain? Is it a scam?

It is not a scam. Generally speaking, the blockchain is still in its infancy, and many projects have not yet been implemented. Only with respect Only by being steadfast and cultivating step by step under the premise of the growth law can it gradually mature. Technology is neutral, but it is human nature that determines the direction and outcome of technology. How blockchain and digital currency will develop in the future depends on the values ​​​​and civilization of the controller.
Blockchain can allow you to make money in this industry, but it can also make you bankrupt. Therefore, I would like to remind users that they need to be cautious when investing. Don’t let yourself get involved without making money, and the gain outweighs the loss. There are also many blockchain scams. We must also be more vigilant to avoid being deceived and causing unnecessary economic losses.
Expand information
Pre-loan stage
Blockchain technology can first be applied to the logistics supply chain to help banks and other lending institutions more comprehensively and accurately grasp the real main business, transaction background, and financing of small and micro enterprises. Downstream affiliated enterprises, as well as their negotiating position in the supply chain, product sales, rhythm and path of payment, etc., on the one hand, help more light-asset, high-growth high-quality enterprises obtain financing support through transaction bills, logistics documents, etc. On the one hand, it prevents problematic enterprises from falsifying their business background and capital needs to obtain loans.
In addition, blockchain can also be applied to the provident fund interconnection to help banks understand the actual payment status of social security, provident fund, etc. of shareholders, executives, and ordinary employees of borrowing companies, so as to reasonably evaluate the size of the company's personnel and operating conditions, and provide credit and loans. Provide sufficient basis for approval decisions.
Loan stage
Blockchain technology can be applied to corporate loan information review and mortgage and pledge review to help banks improve approval efficiency and ensure approval quality. In the financing process of enterprises, especially small and micro enterprises, they often need to provide contracts and other necessary materials. Paper-based contracts with multiple signatures and seals are not only inefficient, but also have a series of problems such as forgery, alteration, and false signatures, which bring problems to bank approval. Greater counterfeiting, fraud and credit risks.
With the support of blockchain technology, relevant real-name information subjects, orders and ordering processes, electronic contracts, agreement signing processes, subsequent supplementary agreements, and photo materials can be preserved in real time, and all stored certificates cannot be tampered with. Ensure that the bank quickly authenticates and approves, and efficiently resolves disputes when they arise. In addition to traditional real estate, other assets owned by enterprises and business owners, including bank financing and other financial assets, can also be used for transfer and pledge, becoming a qualified basis for credit enhancement that can be accepted by banks, improving the availability and immediacy of corporate credit. .
Post-loan stage
Blockchain technology can be applied to the timely assessment of an enterprise's production and operation status and ability to perform repayments, helping banks to effectively grasp credit risks and adjust post-loan risk control strategies at any time. In past business practices, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of an enterprise's operations in warehousing and exiting on the market value of remaining mortgages and pledges. Pledge against warehouse receiptThe ability to control new types of loans such as loans is relatively low.
After switching to digital warehouse receipts supported by blockchain technology, product quality, quantity, specifications, photos and other information can be completely and standardized on the chain, authenticity and traceability are fully guaranteed, and banks can technically prevent Enterprises and warehousing institutions fabricate warehouse receipts and inconsistencies between warehouse receipts and warehouse entry and exit information to ensure that post-loan management is effective. In addition, information such as factory buildings and office building leasing of borrowing companies can also be fully shared with banks, upstream and downstream enterprises and other intermediary service agencies through blockchain technology, minimizing the risk of money being lost and other issues such as "people leaving the building empty".

B. Bitcoin’s “Wealth Creation Movement”: I entered the market with 500 yuan and became a millionaire in 2 hours

Bitcoin, a currency that was only created 12 years ago , is becoming more and more crazy.

It is the first encrypted digital currency. In 2008, the geek Satoshi Nakamoto proposed this concept and it was officially released on January 3, 2009.

It has the basic properties of money: it can be traded, it can be saved, and it can exist as a measure of value.

But what is different from the legal currencies of various countries is that it is not issued by a specific monetary institution, but is generated based on algorithms.

Transactions are not controlled by a centralized organization. Instead, cryptography is used to encrypt transaction information and embed the information into blockchains one after another.

It is different from the current legal currency in form, use and transaction methods, and is limited in quantity and scarcity. This makes many people consider not only its monetary attributes but also its currency when purchasing Bitcoin. investment properties.

In the first month of 2021, Bitcoin ushered in a wave of rapid rise. On January 9, Bitcoin rose to nearly US$41,000, with a market value exceeding US$765.4 billion. Facebook. Compared with when it was first used as currency, the price has increased more than 12 million times.

However, Bitcoin will not continue to rise. On the eve of the release of this manuscript, Bitcoin plummeted, with a liquidation of nearly 10 billion in 24 hours, and 180,000 people became victims of liquidation. .

This microscopic story tells about a group of people who buy Bitcoin. Among them:

Some people buy Bitcoin because they think it is rare and expensive, and they look at others I just followed the trend when I bought it, but I didn’t expect that I would earn 5 more years of salary because of Bitcoin;

Some people are interested in technological innovation because of watching American TV series, and are willing to make value investments in the underlying blockchain technology of Bitcoin. She looks at Bitcoin from the perspective of an early equity investor and believes that it has a promising future;

Some people use a valuation model to value Bitcoin and think it is a perfect investment, except for one car in their hands. In addition to cars and living expenses, 99% of the assets are invested in Bitcoin;

Someone was pulled into the car by the boss and used 100,000 RMB to buy coins, using 10 times leverage, and in 2 months, 100,000 became 2 million...

The following is the true story about them:

Text | Xiaobei

Editor | Zhuoran

In 2 months, 100,000 turned into 200 Thousands

Buying coins allows me to buy a car and a house to improve my life

Key is a practitioner of a digital currency exchange

In 2018, I joined a domestic digital currency exchange. At that time, in order to familiarize myself with the entire exchange process, I started speculating in coins, but I did not expect to make much money from coins.

In the early days, what I played most was air currency (a virtual currency without the support of physical projects).

When many popular air coins are listed on the exchange, the price will be speculated to a very high level by some people. It may be an own index (stock traders, traders, stock investors, etc. accidentally hit the wrong price when trading) Price, quantity, buying and selling direction and other information), it may also be that the enthusiasm of buyers in the market is too high.

At that time, I basically earned 3 to 4 thousand dollars, or even more, with just 1 to 2 thousand dollars.

When I made the most money, I once picked up more than 300,000 yuan in chips at a cost of 7 yuan from a large private equity investor. However, the project team ran away and only made 10,000 to 20,000 yuan in the end.

In April 2019, I started to play Bitcoin heavily. When the boss of our exchange found out about it at that time, he ran to my desk and said excitedly, "You must try contract trading."

Out of trust in the boss, I went to the Bitcoin price of 4,000 When it came to U.S. dollars, I spent 100,000 yuan and opened a long position with 10 times leverage. At the end of the quarter, that is, the end of June 2019, 100,000 yuan turned into 2 million.

This time the contract allowed me to accumulate principal. Later, I successively bought through contracts and cash, accumulating a certain amount of Bitcoin.

But the process of investing in Bitcoin is not smooth sailing.

In March 2019, I experienced a Bitcoin contract liquidation. At that time, the price of Bitcoin dropped directly from about 10,000 US dollars to more than 3,000 US dollars. The liquidation point was more than 4,000 US dollars. I stopped the loss by 400,000 US dollars, accounting for 10% of the entire position.

During that time, I was in a very bad mental state for several days in a row. I was in danger of almost losing my entire position. I’m scared to think about it now.

At that time, the price of Bitcoin fell to the bottom, but out of caution, I did not dare to buy it at the bottom, and of course I did not sell it.

I have done some swings before. In October 2020, the price of Bitcoin was basically sideways, adjusting back and forth between 10,000 and 11,000 US dollars. I originally wanted to do some swings to make a little money, but I didn't expect it to go short. Later I bought it back and lost tens of thousands.

These are all previous investment attempts. Now that the amount of funds is relatively large, I don’t want to take too high risks, so I don’t hold the spot, open a small-capital contract to earn living expenses, and enjoy the dividends brought by Bitcoin.

In this process, I have experienced many people's liquidations and witnessed many people's sudden wealth.

For example, an exchange boss announces the closure of the exchange, and users can withdraw funds. Because he has achieved true financial freedom and no longer wants to work for the company.

Another person’s 500 RMB turned into less than 1 million within an hour or two, and then his position was liquidated instantly.

For example, a certain big boss was targeted with needles and his position was liquidated to US$80 million (approximately RMB 510 million).

For example, the exchange was blamed, and even the interns cooperated with the investigation and went to drink tea.

In my opinion, contract trading is actually not much different from gambling. When you have no money, you can also think about turning your bicycle into a motorcycle. If you have money, you don’t want to take such a big risk. .

I am still optimistic about the price and value of Bitcoin in the long term. I am prepared to add positions when it falls below. I am not afraid of adding spot positions. In fact, now it seems that the possibility of a big drop is not very high. I think it is unlikely to see it fall below $20,000 again.

Everyone’s consensus has strengthened, and the funds for short positions are now much lower than those for long positions. Without a major black swan event, it is difficult to fall below.

I don’t care much about the daily rise and fall now. If it goes up, I’m happy; if it goes down, do something else and forget about it. I’ll look at it after a while and it should be back again.

After making some money, your mentality will indeed change. When looking for a job, you will no longer consider the salary issue, because now you do not rely on salary to improve your life, and the salary is only used for daily food and drink.

When buying things, you don’t look at the price anymore. You can buy things like cherries and strawberries weighing ten kilograms without feeling any pain. Now I have a car on hand, which I bought through earning money from the contract. Although I didn’t buy a house with Bitcoin, I still have it.

After experiencing the rapid rise and fall of Bitcoin in the past, my current investment strategy is becoming more and more cautious. Because I have a family and children, I will pursue stability as a whole.

But I won’t sell it again.

Mine your own coins, buy your own coins, and make value investments in Bitcoin

I will not sell until I feel a sense of accomplishment

Kaka primary market fund practitioner

In 2017, I was working as a financing consultant in the primary market, and there were colleagues working on blockchain projects. That was the first time I heard about Bitcoin.

In 2018, the economic environment went down, and I found that the money in the market was getting smaller. In addition, many entrepreneurial projects began to have difficulty in getting money. I began to reflect on the problems in the industry, learn financial and monetary knowledge, and understand the economic cycle. Only then did I realize that blockchain is a disruptive technology.

So I tested the waters in the second half of 2018 and bought 100 yuan of Bitcoin. In addition, I made fixed investments once a month and bought at low prices. At the same time, I also started mining.

Around 2017, the price of Bitcoin increased, and many people invested and became mine owners. But then the price of Bitcoin fell, and it was difficult for the mine owners to recoup their losses, so they made a decision: rent out their computing power.

At that time, a 180-day computing power package was released, telling you how many you can mine. The computing power package I bought at that time could mine 3 or 4 RMB worth of Bitcoin every day. It will then be configured into my wallet.

But now that Bitcoin is soaring, this kind of computing power package has been robbed.

During the epidemic, Bitcoin fell particularly sharply for a period of time. At that time, no mining factory could recover its costs, but buying computing power and Bitcoin were extremely cost-effective. Unfortunately, I was timid at the time and only bought 5,000 yuan of Bitcoin. Now I feel like I lost a lot.

There is a saying in investment: "You can never make money beyond your knowledge." This is also common in Bitcoin.

When you don’t understand what Bitcoin is or don’t understand the value of Bitcoin, you have no way to make this money.

I think Bitcoin is a new economic system, and sooner or later, everyone will eventually be integrated into it.

Bitcoin has two risks:

One is regulatory risk;

Countries where digital currencies appeared early, such as Germany or the United States, have already We have acquired some relevant experience and processes and are trying every means to incorporate digital currency into the regulatory process. However, China currently has no relevant policies. What the country will do will become a risk point.

The second risk is what academic theories have been discussing: quantum computers;

The entire operation process of Bitcoin is based on mathematical operations, but the computing power of quantum computers is very high. Strong, this will subvert the entire underlying logic of blockchain technology. But this part of the discussion is still in the theoretical world. It will take a hundred years to build a very mature quantum computer.

So I think that within 20 years, the industrial technology revolution will not be able to subvert it.

Short-term fluctuations are normal, because now that Wall Street has begun to enter the market, the market makers will pull the market up and down, pushing small stocksThrow it down and make your own money.

A smart way is: don’t buy it and look at it a few years later. It will definitely rise.

Currently I am making 90% return on Bitcoin.

Even if Bitcoin rises in the future, I will not sell it. I am optimistic about the technology of blockchain and Bitcoin, and hope to watch it grow step by step, and wait until I feel a sense of accomplishment before I make a move.

99% of assets are invested in Bitcoin

A perfect investment, the more the currency depreciates, the higher the price of Bitcoin

Little A, a Bitcoin fund practitioner

In 2018, my friend and I were having dinner and chatting about Bitcoin. At that time, its price had gone from hundreds The dollar went up to $20,000, which piqued my interest.

As my knowledge upgraded, I began to increase my position in Bitcoin. Starting from the second half of 2019, I would buy some Bitcoin as long as I had spare money.

The logic of how Bitcoin and the entire system behind it works is perfect.

We have a valuation model in the industry, the S/F model, which can be simply understood as a model comparing stock and flow.

Figure | S2FX cross-asset valuation model

When we compare the price of Bitcoin with its scarcity, we will find that there is a strong positive correlation between the two. The positive correlation coefficient is very close to 1.

In other words, if the scarcity fluctuates by one unit, the price will also fluctuate by one unit, and the value time is 10 years.

There are only 21 million Bitcoins in total. Its scarcity is certain, and the longer the time, the higher the scarcity, and its future price will continue to spiral upward. Judging from the data of the past 10 years, this is indeed the case.

Figure | Price channel after the third halving

After the epidemic, my colleagues and I have a judgment that central banks of various countries, represented by the Federal Reserve, will conduct a round of substantial adjustments. Loose and loose monetary policy will release a large amount of liquidity into the market.

In 2020, the M1 of the United States increased by more than 50%. At that time, the Federal Reserve distributed 21% of the world’s U.S. dollars to the market. That is, 21% of the world’s U.S. dollars were in 2020. Printed in 2010, how terrible this is!

Both the U.S. dollar and the euro are releasing water, and a large part of the released liquidity has entered the financial system, allowing financial assets to expand.

Bitcoin’s anti-inflation properties are very strong, even higher than gold.

The scarcity of gold is based on physical scarcity, and the mining of gold willThe total amount of gold maintains a relatively high growth trend. But Bitcoin is based on absolute scarcity at a mathematical level, and as halving progresses, Bitcoin will become even more scarce in the future.

At this stage, the biggest investment risk is the risk of holding cash. The purchasing power of legal currency is shrinking, and a fixed amount of Bitcoin can be a good hedge against excessive currency issuance.

The more fiat currency is issued, the more the purchasing power of fiat currency will depreciate, and the purchasing power of the Bitcoin I hold will appreciate accordingly.

Based on this consideration, except for a car and some basic living expenses, all the rest of the money I have is invested in Bitcoin, and the average purchase price is about seven to eight thousand US dollars.

Because I entered the market late, there are many people who entered the market early and had lower investment costs than me. But in the future, I hope to achieve financial freedom through Bitcoin investment.

The analyst who proposed the S/F model later proposed a cross-asset model through which to observe the main stages of Bitcoin: the first halving, the second halving, and the The past halving on May 12, 2020 was used to compare the market value and scarcity of gold and real estate.

After analysis, we found that they are highly correlated, and the future valuation of a single Bitcoin should be close to $300,000. Citibank also issued a research report, believing that Bitcoin will reach $318,000.

But we believe that in the long term, the price of Bitcoin is much more than $300,000. Hal Finney, who developed the system with Satoshi Nakamoto, estimated before his death that the value of Bitcoin was equivalent to the wealth of all households in the world, which was about $100 trillion.

According to this estimate, the price of a single Bitcoin is more than 10 million US dollars. Moreover, because the central bank continues to release money, the price of Bitcoin will increase, and its price ceiling will be very high.

However, I don’t recommend that you rush to buy immediately. There are always opportunities to make money in the capital market, but your capital is limited. I suggest that those who want to buy should read more books and wait until their understanding is in place. Only then can you make money.

You should also pay attention to some pitfalls when buying. For example, during the deposit and withdrawal process, if the funds are attached to some unclean money, your bank card may be frozen.

Another example is custody risk. The private key is the highest authority to control Bitcoin assets. If the private key is lost, your Bitcoin will be gone.

Nowadays, the private keys of most people in China are held by exchanges. This is equivalent to someone else keeping your bank card password, which is very dangerous.

Another example is the risk of futures. Many exchanges have derivatives related to Bitcoin contract products, and the leverage ratio is very high, as high as 100 times or even 1,000 times. This kind of risk is extremely high.

On March 12, 2020, the global financial market was greatly shaken. Many institutions were the first to replenish liquid assets, and the cryptocurrency market became the firstA hacked object.

We have a customer who managed more than 20 million Bitcoin futures for others. At 6 p.m. that day, he went to take a shower after dinner. He was fine before taking a shower. After he came out of the shower, his position was liquidated with more than 20 million. , the price plummeted all of a sudden, and it was too late to close the position.

He opened a leverage of 20 times and his losses were staggering.

The Bitcoin market itself is highly volatile. If you add dozens of times of leverage to a highly volatile market, you will definitely make more profits. However, you will lose money very quickly after falling, so you must be careful.

I will not sell my Bitcoin in the short term. It is unlikely that it will fall below 20,000 US dollars. If I sell it, it will be difficult to find a low price to buy it back.

Unless there is an emergency at home where money is urgently needed, I may cash out some, but I won’t throw it all away. Bitcoin is really a good asset now.

I earned my salary from Bitcoin for 5 years

Everything I bought is going up, and its price comes from everyone’s consensus on it.

Staff of Tingyou Internet

As early as seven years ago, I knew about Bitcoin, but I was not very interested at first. I just think it's a scam.

In 2017, my wife started working on digital currency. It happened that Bitcoin was also experiencing a bull market at that time, and people in my wife’s company were following the trend and buying Bitcoin. I also followed the trend and invested tens of thousands of dollars to buy Bitcoin.

My wife and I are very afraid of risks. We have never touched contracts or leverage, and we only dare to take the spot price of Bitcoin. During that bull market, especially when it was near its peak at the end of December, Bitcoin could rise by 10 to 20% in one day.

I still remember that one day I swiped the price of coins on my way to get off work, and it increased to 100,000 yuan a piece. I was so happy that I felt like I already had the 10,000 yuan I earned lying in my pocket. !

However, after reaching the peak, Bitcoin quickly fell to $3,000. Because we were not sure whether it could rise back, we did not sell or continue to buy. Now we are short.

Several of my wife’s colleagues were optimistic about the rise of Bitcoin during that time and bought a lot. In the following months, Bitcoin rose to $13,900, and they made a lot of money.

There is a classmate who has just graduated a year or two and has been working on contracts. He made tens of millions in a few months of that year.

With the success stories of these people, I started to enjoy thinking about Bitcoin. Why does it rise?

I once thought Bitcoin was "air". People usually buy stocks and funds based on company performance, but Bitcoin does not have an entity that can be evaluated.

Its price is a consensus. We think it is valuable, and its price will gradually increase.

Some people think that Bitcoin is not constantly issued like legal currency, with a constant quantity and value; some people think that the underlying blockchain technology of Bitcoin is valuable, and some people think that encrypted digital currency is The concept has value...

Everyone has their own interpretation of Bitcoin, and they buy Bitcoin because they believe in this interpretation.

These explanations continue to strengthen. More people know about Bitcoin and want to buy Bitcoin. Coupled with inflation, the price of Bitcoin is getting higher and higher, and these explanations are further strengthening themselves.

According to the current trend, these explanations cannot be falsified, which is the core of its rise.

Bitcoin is very similar to the previously popular Dutch tulips. It is precisely because the players have a consensus that the price will rise.

But the difference is: tulips can be produced continuously and in large quantities. As the supply increases, tulips will become less and less valuable.

The number of new Bitcoins is getting smaller and smaller.

When Satoshi Nakamoto created Bitcoin, he took the quantity issue into consideration. The number of Bitcoins mined will be halved every four years. Maybe you can mine 50 Bitcoins in 10 minutes at the beginning, but after 4 years, you can only mine 25 Bitcoins in 10 minutes, and in another 4 years, you can mine 12.5 Bitcoins, and so on.

The number of entire Bitcoins is fixed and certain, only about 21 million. This is the supply side, the number of Bitcoins is fixed.

On the demand side, more and more people want to buy Bitcoin. Now that there are exchanges and electronic wallets, it is becoming easier and easier for everyone to buy Bitcoin, and the purchase demand can be further stimulated.

For example, there are some trust funds in the United States that use retail investors’ money to help buy Bitcoin, and can collect US$500 million in commissions every year.

They don’t need to do any research, and they can make 500 million US dollars every year. How easy it is to make money!

Therefore, a large number of institutions in the United States have poured in and established Bitcoin funds to help retail investors purchase. Over-the-counter institutions and retail investors continued to enter, which also caused the price of Bitcoin to rise rapidly.

After the price of Bitcoin rises, everyone will be more optimistic about the future of Bitcoin and firmly determined to hold it. In this way, the consensus will become more and more condensed, and it will condense faster and faster.

In March 2020, due to the epidemic, the price of Bitcoin fell rapidly.

We bought it immediately without much hesitation. On average, the average price of Bitcoin purchased at that time was less than US$4,000, but the money we earned was equivalent to my five-year salary income.

I am still optimistic about Bitcoin in the future. Under normal circumstances, I will not give up holding it, unless the family needs large expenditures, such as buying a house, which may be sold.Drop part of it.

Bitcoin’s current rise and price are already somewhat risky. If I were asked to spend more than 200,000 yuan to buy a Bitcoin now, I would still feel guilty.

But I think that if a family has spare money, they can allocate one or more Bitcoins as a family investment. I think the price of Bitcoin will get higher and higher in the future, and it will only get harder and harder to get on board.

C. Is it a scam to dig for digital currency every day and get coins for shopping without investing money?

In recent years, the violent price fluctuations of virtual currencies have attracted widespread attention, and there are legends about getting rich overnight. Many people began to rent and buy equipment and join the "mining business". Some people, under the guise of selling computing power (the ability of mining equipment to mine virtual currencies), use "high returns, referral rebates" as bait to lure victims to invest, develop offline, build a pyramid scheme network, and obtain illegal huge profits. In 2018, Wang Shengguo, a university graduate who lives in Suzhou, turned his attention to virtual currencies due to the downturn in the industrial company he started his business. In June of the same year, Wang Shengguo met several people on the blockchain forum. They were very optimistic about the development prospects of virtual currency, so they hit it off. Wang Shengguo became the legal person of the company and jointly established a Miyun Technology Company (pseudonym).

After the company was established, its business mainly focused on “mining machines”. The so-called "mining machine" specifically refers to a computer with a large-capacity hard drive and high-performance graphics card used to "mine" virtual currencies. By selling "mining machines", the company then collects the profit from the sales of the machines and the operation and maintenance fees of the machines entrusted by customers to manage them.

Du Ziming (pseudonym) from Shanghai is the developer of P-coin, a new type of virtual currency. In particular, he needs partners with large computing power to promote P-coin. At the beginning of 2019, Du Ziming led his project team to cooperate with Miyun Company. Since then, Miyun has basically stopped its external sales business. On the one hand, it provides "computing power" leasing services to Du Ziming's team, who then resells the computing power to the public to "mine" P coins. On the other hand, it assists in providing mining machine demonstrations. , publicity venues, equipment maintenance and other work.

After a period of business contact, Wang Shengguo discovered that the price of computing power had increased five times after being resold by Du Ziming. Why not sell computing power directly? Wang Shengguo began to think more about "business" content.

After discussions with other shareholders, in July 2019, Wang Shengguo formally proposed a business model for selling computing power to everyone at the company meeting: After users register an App account, they need to transfer money to Wang Shengguo's account can obtain the "mining" computing power of P coins (for example, if you pay 2,000 yuan, you can obtain 1T computing power in the App and pledge 300 P coins), and at the same time promise that users can obtain static income and dynamic income - static income The income is returned to the personal Miyun account in the form of P coins at a fixed rate of return of 1.1% per day, and the capital can be recovered in up to 3 months; the dynamic income is divided into recommendation awards, management awards, and leveling awards, which are used to directly develop users. number, total investment in user development, total number of peer usersBased on the investment amount, the rebate ratio is divided into 3-6 levels from high to low to encourage existing members to continuously develop new users.

D. Blockchain wallet scams.

What I want to share with you today is a blockchain wallet scam.

At present, various blockchain projects are flying all over the market. Whichever industry is popular will have which chain and which currency!

These blockchain projects are financial investment projects and are different from the blockchain technology advocated in my country’s key development directions. It is a fund package that uses blockchain technology as a bait for packaging, speculation, hype, and money trapping.

Blockchain is a decentralized super ledger that cannot be copied, falsified, or changed. A technology like this is still used in many practical scenarios in banks, insurance, and large companies such as Alibaba and Tencent.

Many so-called blockchain projects do not have any service targets, so just build a blockchain. Who will they serve? Where will they be applied? It is nothing more than creating a concept. Raise the currency price to make money.

I think there are two types of people who understand human nature best in the world, one is psychologists, and the other is liars. In the eyes of these behind-the-scenes bosses and liars, the new technology of blockchain, mixed with virtual currency, is an excellent story framework that can be used to make money with a little processing.

Those mainstream virtual currencies do not have extremely short cycles and collapse at the speed of light like domestic MLM coins or altcoins. Instead, they fall, rise, rise, rise and fall in a long cycle, just like the stock market. . There is a saying in the currency circle that it is harder to keep money than to be a widow

Therefore, those who have the fantasy of getting rich all day long hold in the hands of these seeds that are said to be able to get rich, but they watch them fall every day. It goes up again and again, up and down again. Isn’t it like sitting on pins and needles? How many ordinary people can sit still?

At this time, the blockchain wallet came into being. “As long as you put the money on hand The virtual currency is deposited in my so-and-so wallet, the capital is guaranteed and the income is guaranteed, and it is quite comfortable to get rich while lying down."

There was once a very popular wallet product that claimed to guarantee principal and provide monthly interest rates as high as 10%-30%. The operation is even simpler than P2P. First deposit the virtual currency into the app account, then turn on the "smart dog" brick-moving mode, and then open the wallet every day and watch the assets rise. That is to say, you can make money while lying down.

Moreover, as long as you use the compound interest investment model and recruit people, the annual return is conservatively estimated to be 700%! If you recruit people to level 10, the rate of return will be 1400%! All fools know that it can Get rich!

Haha, this is the skill of a trader. One product can clearly arrange the psychology of the leeks!

The so-called wallet, to put it nicely, is called "quantitative trading bricks", but in fact, it is just a disguised fund disk. The essence is fixed rebates. In fact, those traders in the past found that consumer rebates are not easy to use, so they started to package them. Seeing that the blockchain is hot now, they used mainstream coins to make an article. I packaged a wallet and said My wallet has high-frequency cash out and high-frequency trading functions. In the past, you used to use money to buy products, or you gave me money directly. You are worried. Now I don’t want money. You use the money to buy Bitcoins. Then put your Bitcoins in my wallet, and I will give you interest every day of the month based on the amount of coins you put.

Well, Bitcoin is money, and you bought your coins with money. In the end, he may shut down the Internet and run away, then take all your coins and go to the transaction himself. All cashed out.

You want his interest, he wants your principal!

The blockchain wallet model is actually a model that uses fixed rebates to attract investors. The difference is that the deposit is virtual currency. The most typical blockchain wallet is the plus wallet.

For example, after you deposit Bitcoin, you will receive rebates every day. The source of the rebates claims to have smart arbitrage as an income. source, and then return you the platform currency, and then exchange the platform currency with a digital currency in the international market, and then go to Huobi.com to withdraw cash to obtain profits. When you withdraw cash, you will be charged a handling fee. For example, if you withdraw within 28 days, you will be charged a 5% handling fee. If you withdraw after 28 days, you will only be charged a 1% withdrawal handling fee.

It was officially launched on May 1, 2018, and the plus wallet trading platform was launched in October. It collapsed in June 2019. After running for more than a year, this disk package became one of South Korea’s Team operation is actually driven by the Chinese. Six traders have been arrested by the Chinese police. This project has 1 million members participating and the funds involved reach 20 billion yuan.

Judging from the running time, this product has a long existence cycle, which should be beyond the imagination of many people at the beginning. The reasons are:

First, it uses What you invest in is virtual currency, and what you withdraw is also virtual currency. For these mainstream currencies, Leeks have better illusions, thinking that there is still a lot of room for appreciation, and it will be more profitable to keep them. Since it is just a matter of putting it forward, why not continue to put it in the plus wallet to get the profits? To a certain extent, it delays the time of large-scale withdrawals.

Secondly, Plus Wallet spent a lot of money on publicity. One moment it sponsored some blockchain conference, the next it talked about developing new products and launching new systems, and the next it talked about going public. The purpose of this crazy campaign is to exchange time for space.

The following is a detailed introduction to several blockchain wallet routines:

The first point is that the so-called arbitrage cannot support your subsequent rebate income.

Because the real income from moving bricks is not a stable income, and it will not be as substantial as he described.

Like the plus wallet, based on the rebate data before the crash, it needs 700 million yuan in rebates every day to continue operating, so this number is astronomical. Obviously there is no way to do smart arbitrage. If you think you can, then you have nothing to do with it. With such high skills in moving bricks, do you still need to rely on rewards to attract people? You can move it yourself, and there are big institutions rushing to invest, so there is nothing to do with you!

The second point is that the money returned by the platform to the people in front is mainly the funds coming in from behind, which is exactly the same as the characteristics of the fixed rebate plate.

If you want a promotion reward system with up to 10 levels, as well as super high rebates, you also have to pay high deposit interest. Therefore, soon the subsequent funds will not be able to keep up with the speed of rebates, and problems will arise in the capital chain. The platform will shut down and run away.

The third point is that the platform currency exchange channel for Bitcoin can be closed at any time. As for when to close, only the trader can decide, so you are faced with huge risks at any time.

Point 4: It is stipulated that you will be charged a 5% handling fee for withdrawals within 28 days, and you will only be charged a 1% handling fee for withdrawals after 28 days. This purpose is to allow you to extend the withdrawal time as much as possible , he can deposit more funds into the capital pool.

Originally, everyone entered the currency circle because it is a decentralized technology. You store the currency in a real wallet, and as long as you keep your private key, no one can take it away from you. assets.

As a result, you hand over decentralized assets to some centralized platforms far abroad.

Let’s analyze it from another angle

The private key is a 256-bit binary code, encoded into numbers and letters. Finally, it is mapped into words to facilitate memory, also called mnemonics.

Some wallets have different mnemonics. The mnemonic phrase for plus is a bunch of random characters. Some wallet mnemonics must be made in Chinese, etc.

In short, the core of the blockchain wallet is to allow you to deposit mainstream currencies into his wallet, and then return to you a lot of their platform coins. Your currency is money, and its currency can only be coins. If you recommend others to come here to deposit coins, you will also get promotion benefits. In fact, you can understand its essence if you think about it. It is the same as getting money back, but it is just using coins. Then I will tell you my capital flow. It’s safe, you don’t have to worry about crashing or running away, because I don’t touch the money, so who am I kidding?, Coins are not money, right?

Do you want to make your mnemonic phrase different and import it into another wallet? It is definitely not possible. Only your wallet can use it. Wouldn’t it become a completely centralized platform?

E. What is the popular explanation of blockchain

Blockchain is a technology based on which many applications have been produced, including all industries related to data and information. Business, Bitcoin is one of the most well-known applications.

The popular explanation of blockchain is that if you buy a lipstick online, you first find the product you like and place an order with the seller, first give the money to the intermediary platform, and wait until the seller ships the goods and the buyer confirms receipt. In the future, the intermediary platform will transfer the money to the seller. Because of trust issues, buyers and sellers rely on the intermediary platform. As a decentralized distributed ledger database, blockchain focuses on removing this intermediary platform while solving trust problems at the same time. question.

Blockchain Precautions

Before investing in a project, you must do enough homework and learn more about the future development prospects of the project through various channels. Including the profit model, valuation space, and project team, all need to be understood in detail. It would be terrible to invest money without knowing what the project is about.

Never take advantage of it. The blockchain industry has just emerged and the market is still blank, so there will be many good projects related to it. We must not invest all our funds in one project, even if this It doesn’t matter if the project is very good. You must know that any project may not succeed, so you must learn to diversify your investments. Diversifying your investments means diversifying your risks.

F. Which virtual currency platform is the best?

The concept of Bitcoin was first proposed by Satoshi Nakamoto on November 1, 2008, and was launched in 2009 Officially born on January 3rd. The open source software designed and released based on Satoshi Nakamoto's ideas and the P2P network built on it. Bitcoin is a P2P virtual encrypted digital currency.

G. What is blockchain

Why do you think the country attaches so much importance to blockchain? The central bank also issued the world’s first sovereign digital currency DCEP. This technology seems to have nothing to do with us. What is the difference between it and current mobile payment? Have you ever had similar doubts? It’s a bit brain-burning, but it will definitely allow you to fully understand the core value of blockchain.

Let’s review first. In the era before e-commerce, how difficult was it to buy something off-the-beaten-path? You either had to go around a lot and spend a lot of time going to various places. Or directly find an intermediary to pay a high cost and let them buy it for you, right? Because our transaction requires the cost of information matching, which is how the buyer's needs are received by the seller.. This process of information transmission is either done by someone or by a robot. You may be confused, aren't we talking about blockchain? Why have we come to this point? Hey, don’t worry, if you want to understand blockchain, you must start from the nature of economic activities.

All economic activities in our society can be understood as a group of exchanges. Whether it is looking for a job, a buying something, or a live broadcast, they are all sets of transactions, transactions, trading, trading The more and more prosperity there is, the more developed the economy will be. But there's always something standing in the way of a deal being made, and that's transaction costs.

There are several types of them. The information matching cost of the transaction we just talked about is one of them. For a long period of time, your family has something to sell, and I just want to buy it, but I don’t know you, this deal can’t be concluded. Until the emergence of the Internet and big data, everyone can suddenly start hooking up quickly. All sellers and buyers can complete the deal without leaving home. This is technology. Progress has significantly reduced the cost of confidence in transactions, creating a 20-year boom in e-commerce. But once the transaction intention is reached, can we make bold transactions with confidence?

At this time, the second obstacle to the transaction jumps out. It is called trust cost. For example, before signing a contract, you must check whether the other party is from Earth, right? If he is a Alien, what contract did you sign for him? Also, you must check whether he has the corresponding qualifications. If it is illegal and has no resources, you will not sign. But this inspection process costs money. This is the cost paid for trust. Furthermore, why do we need to sign a contract? That's because if the other party violates the contract, we can file a lawsuit and we can get legal protection. The reason why the contract is credible is because there is a whole legal system behind it to provide protection, but this system requires money to operate. Where did the money come from? Of course, it is extracted from each of our transactions. Each of us is paying a huge cost for trust in the transaction process, because trust is based on information transparency, and people are naturally motivated by interests. As for panic, both parties to the transaction are trapped in a prisoner's dilemma. In the end, in order for the transaction to proceed smoothly, we have to introduce a trusted third party to break this dilemma.

We need to read the next sentence carefully. We have never trusted the counterparty of the transaction, but because we trust the third party, the third party has proved that the other party is reliable, so we indirectly trust This is one of the basic systems that our entire society operates now, but ah, all of our current trusted third systemsThe three parties are basically composed of people, and any system that uses human power as energy must be lower in efficiency than professional institutions. Looking at the entire history of human development, it is a process of constantly replacing human power with machines. We We invented the wheel to replace shoulder and hand movements, we invented machine tools to replace manual work, and we even invented computers to replace people's core abilities of calculation and reading. So what can replace manpower in the field of trusted third parties? It is the blockchain, which uses distributed storage, zero-knowledge proof, and asymmetric elliptic curve encryption algorithms. In short, technically it is a trusted third party that does not need to rely on anyone and cannot be tampered with.



So, if our legal digital currency DCEP application matures, what will happen? The cost of trust will be further reduced, and the friction cost in transaction behavior will also be reduced. Ultimately, it will trigger fundamental changes in the business, taxation, law and even governance methods of the entire society. At least corrupt officials can no longer hide their money, and the impact will definitely be far greater than the current e-commerce.

We should be happy that we live in a very forward-looking country. We are trying to create a new social form unprecedented in human history, and lead the entire world with this change.
