[1.Whether the information is unobstructed.]

In recent years, more and more people have started to talk about Bitcoin with me, and the most common words are:

1. I started paying attention to it many years ago, but unfortunately I didn't buy it.
2. I bought it before, but it was a pity that I got off too early.
3. I should have listened to you at that time, buy some.

In fact, just one sentence: missed it.
Why didn't most people expect Bitcoin to be as brilliant as it is today?
In my opinion, the key reasons that make you miss the Bitcoin opportunity are actually the following aspects:

1.Whether the information is unobstructed.
This one determines your vision and insight.
In fact, most of the channels for people to obtain information are from the circle of friends, and a few are from themselves and have excellent qualities that love tossing.
The level of your circle of friends can determine the quality of the information you get.
If no one tells you, or if you happen to pay attention to cutting-edge technology, it is impossible for you to hear about Bitcoin. You can't search for relevant information on search engines, after all, you can't search for something you don't know at all.

2. Resolution
The more information, the stronger the resolution needed.
It may be better if it is a field that you have always understood, but if it is a field that you did not know before, can you distinguish it correctly?

3. Whether the investment capital is idle？
If the money you invest is from a loan, you will check your account balance every day. Short-term fluctuations will make you not hold it for long. Only after you invest and forget the existence of the money can you hold it for a long time.

4. Mindset and boldness.
No matter what the investment is, it is normal to have ups and downs, ups and downs.
Buffett said that he is fearful when others are greedy, and greedy when others are fearful.
The question is when everyone is afraid, do you really have this mentality to stick to your own opinions? Does the conclusion you insist on must be correct? For example, when Bitcoin crashes 80% for the first time, can you be indifferent, and will double up after being determined, instead of thinking that this is just a scame, and now it’s crashing?

If time goes back 10 years and give you another chance, will you really take out your real money and buy it when Bitcoin is still considered air?
If you are given another chance, will you really insist on not selling after you have made several times the income and hold it till today?
If you were to give you another chance, would you really listen to my advice and allocate a bit of Bitcoin as an asset?
No, you still won’t. After all, I'm not an expert, because you don't believe that the future of Bitcoin will exist like a sea of ​​stars.

Now the impact of the U.S. epidemic has forced the Federal Reserve and the U.S. Department of the Treasury to jointly change the U.S. macroeconomic policy over the past four decades. The crazy rescue plan of the Trump team and the Biden administration has led to a huge crisis in the credit of the U.S. dollar, which is raised by money printing and debt issuance. The U.S. bailout fund has brought inflation.

At this time, people again mentioned that Bitcoin can fight inflation.

Since the total issuance of Bitcoin is limited to 21 million, Bitcoin has had its own "anti-inflation" aura since its inception.

However, Can Bitcoin really resist inflation?

Because, although Bitcoin has a total issuance limit as a "protective cover" against inflation, but under the impact of a dazzling variety of virtual currencies such as ETH, BNB, XRP, LTC, DOGE, etc., Bitcoin's "protective cover" "It's easy to break the power.

The main determinant of currency issuance in the modern economy is not how many physical banknotes are printed by the banknote printing plant, but how much credit the bank issues. If the amount of credit is too large, it will lead to inflation. To prevent inflation, the number of entities that control the base currency is ineffective.

The key is to control the floodgate of credit. Imagine that if Bitcoin really becomes currency, Bitcoin bank loans and Bitcoin bonds will certainly follow.  Can inflation in the Bitcoin world be controlled simply by limiting the number of Bitcoins?

The central bank's quantitative easing policy and the ever-expanding money supply are in stark contrast to the quantitative tightening policy of Bitcoin's third halving. The supply of fiat currencies is growing rapidly, and claims about the scarcity of Bitcoin are becoming more and more important. Can this prove that Bitcoin can resist inflation?I am confused.

Yesterday, a few new friends came to our home as guests, during which we talked about the topic of Bitcoin and blockchain.

A said that the greatness of Bitcoin is not that it is Bitcoin, but that it invented blockchain technology.

B said, no, blockchain technology created Bitcoin, and then there was blockchain before Bitcoin.

C said that their relationship is like the relationship between a chicken and an egg, which is a philosophical issue. It's hard to tell who came first.

D said After the birth of Bitcoin, it attracted the attention of some people. They found that Bitcoin is a good thing. There are many characteristics that modern society does not have. They continue to study it. A few years later, they found that Bitcoin uses a special bottom layer. Technology, they named this technology "blockchain".

E said that if from the order of appearance, there must be basic technology first, followed by technology-based applications. But in reality, everyone has said that they have heard of Bitcoin and not the blockchain. In other words, I heard about Bitcoin first and then about blockchain.
In fact, the reason is really very simple, there are two. 1. Because Bitcoin is so famous. 2. The application must be discovered before the basic technology.
It is also easy to understand that the application precedes the technology being discovered. For example, for ordinary people, they first know about cars, and then about internal combustion engine technology. First know the aircraft, but may not know the turbofan engine technology used in the aircraft

I said that from a technical point of view, the blockchain is known as the underlying technology of Bitcoin, and Bitcoin is the first application of the blockchain.
Therefore, Bitcoin and blockchain are equivalent to the relationship between a table and wood. People first discovered a beautiful table, and later discovered that the material of the table is a good wood, and it can also be used to make chairs, cabinets and boxes. and many more.

Who do you think is right?
What do you think is the relationship between Bitcoin and blockchain?

I found out that I was wrong.Thank you NeuroticFish and Xenon131 for providing information.

I use my superficial knowledge to talk about the risks that may be encountered. If there are errors, please correct me, thank you.

If you talk about the blockchain regardless of security, it's a "rogue"; if you promote the blockchain in the name of security, but you don't have any substantial actions, you are brazen.

The theft of digital currency and exchange security incidents occur so frequently that it has become a reason for the public to question the security of its underlying technology, the blockchain. So, let's take a look at the possible blockchain security risks of blockchain technology.

• the risk of Wallet
  All mainstream digital currencies have corresponding digital asset management tools-wallets. Take Bitcoin as an example. At present, there are dozens of mainstream wallets that support Bitcoin, and they are also divided into Online wallets/hot wallet and Offline wallet/cold wallet.
  
  Due to issues such as historical data, network synchronization, and inconvenience, it is very cumbersome and unrealistic for individuals to run and maintain a huge Bitcoin client to manage assets. More and more digital currency asset management vendors have developed wallet applications or hardware.
  
  In this world, there are always some people who have forgotten the initial key or lost the hard disk due to bad luck or other factors, resulting in the permanent disappearance of digital assets from the network. There are many such cases, and they are often seen in recent news or narratives.
  Charles-TIM Suggestions about the best ways to backup seed phrase More professional and detailed introduction from the forum
  
  
  The mainstream exchange or wallet management software all provide copying or scanning codes to obtain the receiving address, but if the computer terminal is implanted with a Trojan horse, then the receiving address is also at risk of being replaced during the process of copying or executing the transfer.
  
  In addition to security issues such as "passwords", keys and wallet addresses, the wallet app itself also has greater risks. When using digital currency wallets, you should choose officially recommended wallet software, and resolutely do not use wallet software developed by unknown manufacturers or from unknown sources in social networks.
  
• the risk of Mining
  
  1. The domain name of the mining pool server is hijacked, and the client has joined a fake mining pool for mining;
  
  2. If there is a virus in the mining server, the wallet address will be replaced during the mining process;
  
  3. The mining software itself is abnormal, and the wallet address is secretly changed;
  
  4. The mining pool server was hacked, resulting in the transfer of the cryptocurrency obtained from mining.
  
  
  Although distributed ledger technologies are known for their excellent security, this does not mean that they are completely secure. They may still be attacked, and data or information may still be stolen. You should know that blockchain is not 100% secure, and precautions should be taken to ensure security.

[Distinguish mainstream coins, altcoins, platform coins, and meme coins]

Distinguish mainstream coins, altcoins, platform coins, and meme coins

1. Mainstream coins: According to the concept, as literally speaking, it is a digital currency recognized by the mainstream of the currency circle. Generally, they are strictly based on blockchain technology, and have practical applications in the market, and they have gained consensus. From a definition point of view, mainstream coins itself is a dynamic concept, rather than a fixed reference to certain digital currencies. For example: BTC, ETH, BCH, LTC

2. Altcoins: There are real project teams based on blockchain technology to develop in accordance with the white paper plan, there are active community organizations, and most of the tokens are issued in the form of Ethereum smart contracts. The tokens can be used on the digital currency trading platform On normal transactions. For example: DOT, EOS, BTM, etc.;

3. Platform coins: the platform digital asset officially issued by the digital asset trading platform. For example, the platform coins BNB issued by Binance and the platform coins HT issued by huobi.

Compared with mainstream coins, the use scenarios of platform coins are more abundant. At this time, platform coins can flow in a larger range and enhance the economic value of platform coins. More eye-catching application scenarios: discounts on transaction fees of various platform coins, point card discounts for HT coins, VIP and mining of GT coins, and airdrops of BNB coins. With the gradual improvement of the platform, the development of platform currency will be faster and more stable, and there will be no major changes with the market.

4.meme coins：I also called it Aircoin.There are white papers based on blockchain projects, which are issued in the form of Ethereum smart contracts or Pancake directly on the decentralized exchange bsc chain, but there is actually no real technical team following the white paper Development and maintenance are only for the purpose of issuing coins and making money.

(1) Under the cloak of blockchain technology, the technology is far from the real blockchain principle;
(2) The purpose is not to solve, optimize or change a certain business pain point in the traditional industry;

meme coins is a scam. Now the packaging of Aircoin is becoming more and more high-end and secretive. Sometimes it's hard to tell the truth from the false. So once again remind everyone to be careful of all kinds of meme coins. Stay away from it.

Based on the above characteristics, you can form your own investment portfolio. My position is 65% BTC, 20% ETH, 5% BNB, 5% HT, 5% DOT. Note: This is not an investment recommendation.

Cryptocurrency ATM company Bitcoin Depot has announced a long-term partnership with Circle K, a convenience store chain in the United States and Canada.
 Bitcoin Depot plans to install ATMs in "thousands" of Circle K convenience stores. Bitcoin Depot stated that its ATM machines enable users to exchange cash for cryptocurrency, allowing simple face-to-face transactions, giving users immediate access to Bitcoin and more than 30 other cryptocurrencies.
Bitcoin Depot has installed more than 700 Bitcoin ATMs in 30 states in the United States and Canada.

If it is more convenient for people to buy Bitcoin, will Bitcoin be more popular?
If you don’t know Bitcoin, and you see this ATM when you go to buy bread, do you buy Bitcoin with change?
If you didn't buy it this time, when you saw these ATMs elsewhere, would you be curious to buy some?

    I used to be an accountant. Two years ago, I came into contact with a cryptocurrency company in a business, so I resigned and officially became a practitioner in the cryptocurrency industry. Till now, not every friend of mine knows about my new job, even though two years have passed.

    I have suffered a lot of pride and prejudice against investors and practitioners in cryptocurrency industry.
Initially, I talked to my friends about my new job without reservation until I found out that some of them should thought cryptocurrency investors a group of gamblers, the mob.

   Sometimes, friends in the traditional Internet industry would say they want to know my job. I deemed it friendly communication. But when I hadn’t spoken a few words, they would say with confidence, "our company has been engaged in technology for more than 20 years. The underlying technology of Bitcoin is very easy, not difficult for us”, or “what is the value of mining? There is no value at all, just a waste of resources”. They are no fan of the current applications of blockchain. After my explanation, they simply felt that there’s something wrong with my brain. I meant to have heartfelt communication but that turned out to be a foolish act.

   Of course, I have met outsiders with willingness to to accept new things as well. Some don't care about blockchain or disruptive technology. Their only concern is how to buy and then cash out, short-term operators. While others gradually become long-term investors by trying to understanding this industry in trading.

   What would you do to your prejudiced friends?

On July 6, the Central Bank of China closed down a Beijing-based company that provides software services for virtual currency transactions, and reiterated that no institution within its jurisdiction should engage in such transactions.
After the People's Bank of China reiterated its long-standing anti-crypto stance and warned institutions not to provide services to crypto-related companies, Bitcoin cut its earlier gains.
Why does the negative news from China always affect the price of Bitcoin? When does Bitcoin become less sensitive to negative news?
