1. Is blockchain safe?

Hi, everyone, I am your Q&A assistant - Zi Xiaochen. Recently, blockchain resistance has been widely concerned and discussed. But there are many people who don’t know much about its safety. So today we will talk about the security issues of blockchain.
First of all, would you like to hear an easy-to-understand metaphor? A friend of mine joked: "Blockchain is like a password lock. Without a password, no one can open it." Although this is simple and interesting, it makes a lot of sense. Since the blockchain uses distributed ledger technology, data is stored in a huge network, and the transmission between each node uses asymmetric encryption, the blockchain has extremely high security, and third-party attacks are very vulnerable. difficult.
Secondly, of course there are some security issues that need attention. For example, hacker attack methods such as "51% attack" can pose a threat to the blockchain. In addition, there are also security risks in virtual currency trading venues, such as Bitcoin exchanges, and you need to pay attention to precautions. Therefore, when choosing a blockchain platform or participating in virtual currency transactions, you need to know more and consider carefully to avoid losses.
In short, blockchain is an open technology, which has huge advantages in ensuring data security and preventing tampering. But we also need to be alert to potential security risks and choose reliable platforms and exchanges to participate in cryptocurrency investments.
I hope my answer can help you better understand the blockchain and its security issues. If you have any questions or want to share your experience, please feel free to message me privately! Finally, don’t forget to like, comment and forward, follow my articles, more content is waiting for you!

2. The recent popular claim of mining Bitcoin via mobile phones is true or false. Can you mine coins?

As a person who participated in mobile phone virtual mining in 2017, I I can tell you responsibly that a large part of the cloud mining models currently on the market are scams.

The pattern of this scam is basically the same as that of the previous Bitcoin bull market cycle in 2017. The general logic is to provide powerful cloud mining computing power, so that you only need to purchase the computing power on your mobile phone to mine Bitcoin or other encrypted digital currencies.

There are also some who claim to have deployed offline physical mining machines. You only need to purchase the mining machine’s computing power, which is equivalent to leasing the mining machine’s computing power to you. They are responsible for the maintenance of the mining machine and the equipment. Depreciation, and all mined Bitcoins and other cryptocurrencies belong to you.

More than 95% of what can be seen in these two models are scams. First, let’s look at the first type of so-called cloud mining. I was just charging money to buy computing power. The more powerful your computing power is, the more Bitcoins or other encrypted digital currencies you can mine. But many of this model They are just virtual numbers on a web page and can be changed in the background. So the computing power you pay to buy it, and the Bitcoins eventually mined are fake.

Also, even if it can be proven that the Bitcoin or other encrypted digital currencies you mine are real, they will only be temporarily stored in other people's accounts. Generally, in this mobile cloud mining model, coins can only be withdrawn after reaching a certain amount, and it takes a long time to reach this cycle or threshold, which is enough for people to run away.

So we can see that history seems to be repeating itself. Many blockchain scams in 2017 suddenly sprung up like mushrooms after the new bull market of Bitcoin broke out in 2020. Because 2017 was also the last bull market cycle of Bitcoin, so think about it, why did no one recommend mobile mining to you during the bear market cycles of 2018 and 2019?

Since mobile phones can mine, why do most graphics cards on the market increase in price now? Why do they keep looking for areas with cheap and abundant hydropower and thermal power to set up mining farms? So the answer is already very clear. Pies in the sky will not fall for no reason. Mobile phone mining is destined to be futile. More than 90% of these so-called blockchain games or contribution mining are scams.

I am currently digging. Someone recommended me, saying that I can exchange money in the future. There are already 250,000 yuan online. I don’t understand it and I don’t dare to ask. No. I don't know if it's harmful.

You can’t make money in a year, let alone a month. A foreign guy bought a top-of-the-line computer and mined it 24 hours a day. It took him a year to dig out one Bitcoin. Today’s mobile phones, no matter how well configured they are, can’t compare with computers.

This is the first time I have heard of this. I personally think it is unreliable and unlikely. Bitcoin is an S256 algorithm. It seems that mobile phones cannot currently implement this function! But nothing is difficult in the world, as long as there are people who are willing! If someone can use this technology to launch Bitcoin, then of course someone can use it to mine it!

Prepare a few more mobile phones, and you must have a good mobile phone!

I went to a friend’s place to look at T-coin a few years ago, and I thought it was pretty good. However, I am not interested in virtual currencies, and I have played with other currencies before and used computers to mine, but in the end I didn’t make any money, so Nothing interesting!

But Bitcoin is very hot recently! There are many people mining Bitcoin! Most of them are mined with mining machines, but the investment is a bit larger! This has also led to many people having less exposure to Bitcoin! I also briefly learned about mining from a friend. I just had a brief understanding and I am not a player. Let me talk about my understanding below.

As Bitcoin explodes in popularity, all kinds of software are taking advantage of it, and various mining tools have emerged.

For mobile mining, I think it is more reliable to use a computer to mine. Anyone familiar with Bitcoin knows that Bitcoin uses mining machines to calculate a large amount of data.Even if it is obtained, mining is divided into several algorithms and threads! If you want to mine, you must have a safe and stable mining pool, that is, a Bitcoin wallet account. After creating the account, you also need mining software, etc. If these prerequisites are met, you just need a good mobile phone!

Mining is also a test for the CPU and other hardware configurations of the mobile phone. Because the computing power of the mobile phone is too poor, the mobile phone needs to work under high load all the time. It is recommended that you choose mobile mining carefully and don’t leave it to the end: Before the coins are seen, the machine explodes first [face covering]

Coin mining is based on the computing speed of the machine. The average mining machine costs tens of thousands, and you can go there with just a few mobile phones. Mining coins? ? ?

It is only theoretically possible to mine Bitcoin with a mobile phone, including home computers, and there is basically no profit. Mining Bitcoin requires professional mining machines. Unless you can get a lot of mobile phones or ordinary computers, the gain outweighs the loss. In addition, let’s not talk about mobile phone mining, let’s talk about mining with professional mining machines. The price of mining machines is too high now, and the payback period is not short. Once the price of Bitcoin fluctuates significantly, investors will definitely be trapped at the top of the mountain. of. It is recommended that novices not blindly follow the trend and invest in entities if they have money. Even if the profit rate is low, it is at least stable. Don't be impatient just because others are making quick money. You will be cut off at any time.

Any project like this is nonsense. You have used your mobile phone to mine other people's professional mining machines to eat. Moreover, the algorithms, equipment, and underlying technology are completely incompatible. These are all deceptive tricks to deceive people who don't understand anything. I think about people who just lie down and make money all day long! No matter when the mobile phone can not dig. BTC!

I have only mined FIL. It depends on how much computing power you buy. It ranges from a few thousand to tens of thousands a month. I have never mined this before, and I guess I can’t do it [picking my nose]

Mobile phone mining is definitely fake. First of all, professional mining people buy thousands or tens of thousands of graphics cards for mining, or many graphics cards. With a small mobile phone, you can mine and make money like others. Obviously It's impossible. The initial investment in mining is huge, and there are many cloud hosts that you can buy and make money on your own. Don’t believe it. There is no such thing as pie in the sky. If you can really make money on your own, will they give you the opportunity? Stop daydreaming!

3. 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 by respecting the law of growth Only by cultivating it step by step in a down-to-earth manner 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, so 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, upstream and downstream affiliated enterprises of small and micro enterprises, and other Negotiation status in the supply chain, product sales, the rhythm and path of payment, etc., on the one hand, it helps more light-asset, high-growth, high-quality enterprises obtain financing support through transaction bills, logistics documents, etc., on the other hand, it prevents problematic enterprises from fictitious , forging 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 the past business practice, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of the company's operations in warehousing and exiting on the market value of the remaining mortgages and pledges. The ability to control new loan types such as warehouse receipt pledges 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".

4. Is the income from investing in blockchain mining stable?

Well, the amount of income is actually stable, but what is unstable is the price of the currency. This is the reason why your income is unstableTherefore, it is recommended to judge when to invest based on the market situation. If you do not know the market very well, it is recommended to first learn more about investment and financial management on some large platforms, and choose one with longer tenure and more reliability, such as AEX and Huobi. AEX is a very conscientious platform, it is recommended to learn more about it

5. Is it true that Quark blockchain mining makes money?

Absolutely fake, only those who make a fortune silently There is no publicity everywhere. The publicity is currently looking for you to take over the order. You see, you don’t want Bitcoin. Bitcoin is the first currency of the blockchain. Currency is the right of a country’s bank. Bitcoin is too harmful to various countries and banks. They are all resisting. From the current trend, blockchain currency does more harm than good. However, blockchain technology is still very promising but not currency.

6. Is the blockchain a scam?

I can’t say that all of it is a scam, but some of it is indeed a scam

7. Is blockchain mining real or fake?

It depends on whether you choose a formal platform. For example, the Encore computing power I chose is a better platform, and the deposit will be It will be returned to you on time, and the profit will be good. . If you don’t understand, you can ask me again

8. Is mining reliable? Can you still make money mining Bitcoin? An old miner will tell you

Mentioned blocks Chain, I think that blockchain projects can really achieve success in the next 3-5 years, either by being recognized by the world or eliminated by the world. If you want to make money all the way through those chaotic projects in the market, It may not be realistic. Within 5 years, there will definitely be a huge wave of rectification, and it will only become more formalized and unified!

There are many many projects on the market. Cut a wave of leeks cut a wave of leeks. However, the people who really make money are really small and less! So why are so many people willing to try and do it? It is indeed because many players make a lot of money! ! ! And those who really make money are often those project parties! I have been in the industry for four years and have been cheated many times and lost all my money! But I also encountered good projects and made my first pot of gold in life! ! This is also the reason why I chose to be a miner first. Anything that can create a legend must also have its merits, and Bitcoin’s merit lies in the blockchain. Not long ago, the People's Daily published a full-page report on blockchain, including research on the concept of blockchain, prediction of blockchain development trends, and being a leader in the digital economy, calling on the national government to conduct research on the region. Blockchain technology is strongly supported. No matter which angle you look at, it is certain that blockchain is constantly receiving official attention and has penetrated into the economic circle with great momentum. When Bitcoin was first designed, a 140-year mining time was defined. There was a long experimental time for basic technology research and development and iteration. The current progress is beyond expectations. If all the mining was completed today, I believe many One would think that its price would have skyrocketed long agoIt has risen (now a lot of Bitcoins are mined out and put into the market every day to suppress the currency price). However, it has only been digging for eight years so far! It can also be said that it has just begun! The computing power of the entire network has grown very rapidly. At the beginning of 2017, the computing power of the entire network was only about 2E. By the end of 2017, it had exceeded 20E, which increased by about 10 times in one year. Now when calculating mining income, I use a 2% increase in each cycle (about 13 days). If it grows at this rate, it will increase to 5 times in one year, that is, the computing power of the entire network will increase to 28E in June 2018. However, in less than June, the computing power of the entire network has exceeded this value, which is a very large increase.

Are so many people really optimistic about mining?

In the Bitcoin operating rules, every time a block is created, a certain number of Bitcoins will be generated. (The act of creating blocks is called mining.) On average, every four years, the number of Bitcoins generated per block will be halved. It is expected that by 2140, all 21 million Bitcoins will be "produced". That is, as time goes by, the cost of generating new Bitcoins will become higher and higher. It will become increasingly difficult to mine a new coin. Mining output is related to only two variables: mining difficulty and mining machine computing power. The output is inversely proportional to the mining difficulty and directly proportional to the mining machine's computing power. As the difficulty continues to rise, the more mining machines there are, the more Bitcoins can be mined every day. If you don't take action, it will be too late!

Of course, many people ask, if mining returns are low, it’s because you don’t understand mining! Dig first and hoard first, then sell when the price of Bitcoin rises. It is definitely a direct currency speculation, the cost is much lower! ! ! Mining belongs to the level 1 market! In other words, mining belongs to the manufacturer. Do you think the goods sold directly by the manufacturer are cheaper? Or is it cheaper in the supermarket? ? Although the price of Bitcoin has not risen very much recently, the income from mining is still very considerable! ! The real opportunity to make money should be in 2020, so all miners, please save your Bitcoins and ride the rocket together next year! !

In the currency circle, playing with digital currencies and making money rely on opportunities. Opportunities are given to you. If you are not sure, you will just sigh~~Why did you dig it in the first place? Mine can be said to have no reason to hesitate! In 2009, Bitcoin was launched, and it cost 2 cents a piece. Now it costs 60,000 yuan. Who would have thought it? I have been studying mining for many years, and it can be said that there is really zero risk!

Of course, the future value increase of Bitcoin is the key, and investment is a probabilistic event. How long can this game last? I can only say that the sooner, the better! ! ! Can Bitcoin rise to the point where one coin per villa? The answer can only be left to tomorrow.
