⑴ Why are all digital wallets on the market under the guise of blockchain a lie?

With the country’s announcement to accelerate the development of blockchain technology, various companies in the market have There has been a shift in digital wallets and digital currency scammers using blockchain technology in what is described as a state-backed direction. Actually, this is due to some wrong ingredients.

This type of wallet, known as a digital wallet in the market, allows wallet operators to purchase ICO coins from abroad, allowing the operators to speculate on the coins and increase the value of the currency. In short, it's the same as "Postcard". The only difference is that the object name is replaced by "blockchain cryptocoin". As long as everyone keeps money in my wallet, everything is fine. You can say you can deposit 100 today and 1000 tomorrow.

⑵ Why are there so many "scams" in the currency circle that relies on blockchain technology?

Behind any investment with an unusually high return rate, there may be a hidden meaning of "you want to His interest, but he wants your principal" type of scam.

On July 4, 2018, a recording of Li Xiaolai, known as "China's richest man in Bitcoin", was exposed, causing an earthquake in the currency circle. In the nearly hour-long recording, Li Xiaolai made sharp comments on many big players in the currency circle, and also gave "step-by-step" instructions on how to cut off the leeks of retail investors.

Although my country has rectified and banned ICOs according to law in September last year, it is not uncommon for project parties to avoid legal supervision through foreign registration and underground ICO models. This requires regulatory authorities to increase their efforts in governance, establish sound industry standards, and promote the good development of the blockchain industry.

For investors, on the one hand, they must keep their eyes open and not blindly follow the temptation of so-called "Internet celebrities". If you really believe Li Xiaolai’s remarks denying value investing and advocating speculation, then you are playing into his trap and will eventually become a leek that can be harvested by others. On the other hand, you need to invest rationally. Behind any investment with an abnormally high return rate, there may be a scam like "you want his interest, but he wants your principal".

⑶ Is blockchain a lie?

The development of China’s blockchain is uneven and growing wildly. As of August this year, my country’s blockchain The development level of the blockchain industry is at the forefront of the world, and the total number of enterprises ranks second in the world after the United States. Monitoring data from the National Internet Emergency Center’s Key Laboratory of Internet Financial Security Technology shows that there are more than 32,000 companies with the word “blockchain” or whose operations involve blockchain. Chain technology companies only account for about 10%, or even less than 10%.

In other words, there are many organizations committing fraud under the guise of "blockchain"!

Scammer’s routine:

Elementary routine: Big words, high profits

Promotional rhetoric: “You can make a lot of money even while lying down!"

The essence of the scam: using so-called "projects" with professional terminology to claim high returns to raise funds from victims. The essence is financial fraud.

Intermediate routine: playing with concepts and high dividends

Promotional rhetoric: "The benefits of the sharing economy are considerable"

The essence of the scam: illegal fund-raising (such as "Qubu" APP)

Advanced routine: high rebates from currency speculation

Promotional rhetoric: "Virtual asset financial innovation"

The essence of the scam: illegal pyramid schemes (such as various "digital currency" investment projects)

⑷ Why do many people say that blockchain is a lie?

Blockchain is not a lie, but people are cheating in the name of blockchain. People who deceive people under the guise. In fact, blockchain scams take advantage of people’s lack of understanding of the technology, and then scammers rely on a variety of fancy methods to set up scams. Many people only look at the surface when making investments, and are eventually lured into it by high profits. Trap.

In current society, more and more people are willing to take this risk to invest in order to obtain huge returns, but not everyone can make a profit. After all, there are benefits. There are many people squatting in the place, and they will set traps for people to take the bait.

(4) The pitfalls of blockchain currency withdrawal Extended reading: < /p>

Notes

Blockchain is a technology. Simply put: this technology is a new way of data management based on cryptography and other methods. Blockchain technology is decentralized , cannot be tampered with, leaves traces throughout the process, and can be traced, etc., it has broad application prospects. Coin issuance is a behavior derived from blockchain technology. At present, most areas that focus on currency issuance and currency speculation Blockchain applications are suspected of illegal fundraising.

Blockchain technology is still in its early stages of development, and it is difficult to implement applications. If you claim to have an application based on just a white paper, it is a deceptive act in itself.

⑸ There are several people around me who have been deceived by the blockchain

⑹ Remember! Don’t jump into these “pits” in currency trading< /p>

1. Overconfidence in entry signals leads you to trade overly large positions. You must control your trading positions to a certain safety level and do not let belief become the criterion for determining positions.
< br /> 2. Open a position in an illiquid market. You can easily lose money by trading in a market with a large bid-ask spread.

3. Hold on to a losing trade And there is no stop loss at the beginning. Investing in the opposite direction of the market trend will definitely make your small loss eventually turn into a big loss. Big losses are the biggest reason why trading cannot be profitable.

4. Go to failure Invest money in the transaction. This can turn a small loss into a big loss, and your ego increases the cost of the loss.

5. Imagine that you will soonBecome rich. The stronger the desire to be rich, the more likely a novice trader is to take high risks, which ultimately leads to failure. Stay steady and even-tempered to win this trading game.

6. Insufficient funds. Trading with an underfunded account can easily cause novice traders to take overly large positions or take more risks. It is almost impossible to make a profit this way because the commission fee for each trade will be a very high percentage. Formal, more active transactions require at least 5 digits of account funds. The market will still be there when you are ready.

7. Trade markets you don’t understand. The trading itself does not understand the investment, coupled with the ubiquitous risks, it is the basis for failure. Before you can be successful, you must know enough about the market.

In currency trading, avoid the above-mentioned dangers, and then stick to trading in markets you understand. Trading is a marathon, not a sprint. Before the race begins, it is important to determine the correct track and direction.

Conclusion: The market is not a safe haven, but a surfing ground. You can either brave the rapids or stay away. Now that you have chosen to move forward, don't just accept the situation as it comes.

Finally, the author warmly reminds everyone: investment is risky, invest tens of millions, and safety is the first priority. If the investment is not standardized, your loved ones will shed tears.

⑺ 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 is mixed with virtual currencies.It 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 brilliance of a trader. One product can clearly arrange the psychology of leeks!

The wallet, to put it nicely, is called "quantitative trading bricks" "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 transfer the platform currency to the internationalExchange it with a digital currency on the market, and then go to Huobi.com to withdraw cash to get 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.

Let me introduce you to several methods of blockchain wallet in detail:

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 is safe. You don’t have to worry about crashing or running away, because I don’t touch the money. Who am I kidding? Coins are not money, right?

If you want your mnemonic phrase to be different, change it. Can it be imported into other wallets? It's definitely not possible. Only your wallet can be used. Doesn't this become a completely centralized platform?

⑻ Is blockchain a scam?

Blockchain technology itself is not a scam, but it does not rule out that some people use blockchain as a cover to commit scams. Several problems exist in blockchain: 1. The problem of excessive blockchain size. With the development of blockchain, the volume of blockchain data stored by nodes will become larger and larger, and the storage and computing burden will become heavier and heavier. Taking the Bitcoin blockchain as an example, the size of its complete data currently reaches about 71GB. If a user uses the Bitcoin Core client to synchronize data, it may not be possible to complete the synchronization for three days and three nights. Moreover, the data of the blockchain The volume is still increasing, which brings a great threshold to the operation of the Bitcoin Core client. 2. The problem of blockchain data confirmation time. The current blockchain system, especially the financial blockchain system, has the problem of long data confirmation time. Taking the Bitcoin blockchain as an example, the current confirmation time of a Bitcoin transaction takes about 10 minutes. In the case of 6 confirmations, you need to wait for about 1 hour. Of course, for credit card transactions, the confirmation time is 2 to 3 days. Bitcoin has made great progress, but it is still far from the ideal state. 3. Dealing with the problem of transaction frequency The blockchain system faces the problem of too low transaction frequency.Taking the Bitcoin blockchain as an example, the average size of each transaction is about 250 bytes. If the block size is limited to 1MB, the number of transactions that can be accommodated is 4,000. Calculated based on the rate of generating one block every 10 minutes, 144 blocks can be generated every day, which can accommodate 576,000 transactions. Divided by the number of seconds per day, 86,400, the Bitcoin blockchain can process a maximum of 6.67 transactions per second. Currently, the actual daily transaction volume on the Bitcoin blockchain is close to the system bottleneck (picture). If the expansion problem is not resolved, it may cause congestion and delays in a large number of transactions. Average number of transactions per Bitcoin block (Source: Block Yuan) In comparison, Paypal’s overall number of transactions in the third quarter of 2013 was 729 million, averaging 93.75 transactions per second. Information from the official website of VISA, the world's largest payment card, shows that VisaNet achieved a processing capacity of 47,000 transactions per second in a 2013 test. Compared with several major payment networks such as Alipay, the Bitcoin blockchain is more like a newborn baby in terms of transaction processing frequency. Of course, this was also an early deliberate design by Satoshi Nakamoto. The Bitcoin block size was limited to 1MB to avoid the malicious behavior of rogue miners and have a negative impact on people. The reason why the Bitcoin blockchain payment network The reason why it has grown to be worth billions of dollars today lies in its decentralization. 4. The development of blockchain is restricted by the current system. On the one hand, the decentralized and autonomous characteristics of blockchain dilute the concept of national supervision and have an impact on the current system. For example, digital currencies represented by Bitcoin not only pose a challenge to the country's right to issue currency, but also affect the transmission effect of monetary policy, weakening the central bank's ability to regulate the economy, causing monetary authorities to remain cautious about the development of digital currencies. On the other hand, regulatory authorities also lack full understanding and expectations of this new technology, and the establishment of laws and systems may lag behind, resulting in a lack of necessary institutional norms and legal protection for economic activities related to the use of blockchain, which inadvertently increases reduce the risks of market entities. 5. The integration cost of blockchain technology and existing systems is relatively high. For any innovation, existing institutions must ensure that it can not only create economic benefits, but also comply with regulatory requirements and connect with traditional infrastructure. Especially when deploying a new basic system, the cost of time, manpower, and material resources is very large, and the resistance encountered within existing traditional organizations is also not small. Of course, the existence of problems cannot hinder the development of blockchain. The proposal and in-depth research of technologies such as simple payment verification, side chain, and lightning network protocols have provided ideas for solving the above problems.

⑼ 019·Let’s talk about the pitfalls of the blockchain-BCDN

Talk about the pitfalls of the blockchain-BCDN

Can’t write blocks For chain technology articles, just write a story about investment failure.

Thinking back, from entering the currency circle to falling into the trap,Really more. It’s really uncomfortable to think of all the money you spent in vain, being cheated like this...

In order to alert others later, let’s tear open the wound with your hands and play with everyone.

This failure is a trap for BCDN.

In the spring of 2018, while browsing in various blockchain circles, I discovered news about BCDN. This product was still very popular at the beginning. One coin is more than 1 yuan, and you can mine dozens of them every day. You can get your money back in the first one or two months. The technology is not difficult, and the investment is not too big.

I was very excited at the time, and I immediately researched it. There are two investment methods:

Taking into account the technology and home environment, I chose the second method.

So I spent more than 2,000 yuan on Xianyu to buy 2 BCDN mining codes, and then found an agent online for 30 yuan a month.

At the beginning, the official "Berry APP" was normal, the APP was upgraded quickly, and everything seemed to be on the right track. I watched the mines come out every day. Although there were only 20-30 mines a day, the price was only a few cents. But it was also flattering - I also joined the blockchain!

Not long after, BCND plummeted, and the return rate instantly increased to more than a year. At this time, the official launched a plan to earn coins through staking, known as "coin-generated coins", which claimed to have a high rate of return of 20% or something (I forgot the specific details) annually. Many people, including me, have transferred the mined coins to the so-called "coin-generated coins" module.

Soon, probably in the second half of the year, the leaked project in the Q group ran away, and the coins could no longer be withdrawn.

Soon, the APP died. Now, there are still more than 5,000 coins recording the feathers of this place.

Looking back now, the project team was well prepared to run away. Various benefits are constantly being introduced to allow you to lock up your position. When you withdraw your coins, you will be told that there are official maintenance, network congestion, technical failures, etc. The general branch just cannot withdraw your coins, and all kinds of delays will buy time for the project team to run away.

Thousands of dollars were lost on this project. Naturally, there are still people who suffer misfortune, and some people who believe in "Buddhism" have suffered huge losses:
[Image upload failed...(image-7db287-1563011043385)]

This project is about admitting defeat. But I have never figured out why this kind of harmful person can still be traded on many exchanges, or even skyrocketed?

Why?

Please enlighten me.

⑽ TBCC is a scam. It allows members to join for 22,000 yuan. Some leaders of the company deceive everyone by saying that they can’t withdraw coins from a TBCC card.

TBCC is This is a scam, allowing members to join for 22,000 yuan. Some leaders of the company deceived everyone and said that they were given a TBCC card to withdraw coins.

Tan Yonghua, director of the Sixth Research Institute of China Aerospace Science and Technology Corporation, told Media: At present, Chinese researchers have successfully proposed the concept of TBCC turbine-based combined power engine. This will provide technical guidance for our country to manufacture such engines. So what is the magic of the TBCC engine?

In comparison, the U.S. Air Force's X-51A waverider recorded a duration of 210 seconds and reached a speed of only Mach 5. In India, in 2016, the test car even managed just 6 seconds. This shows how difficult it is.

In the editor's opinion, China's breakthrough in the field of TBCC engines is undoubtedly the first echelon in the world and also the leader in future hypersonic weapon research. This will also greatly shorten the interview time for hypersonic weapons in China, thereby forging a sharp sword for China.
