1. bitcoin is valuable under certain circumstances, but it is worthless under certain circumstances. Because it's not legal tender. It is impossible for any country to get the right to issue legal tender to use any mining machine. Bitcoin is just a virtual number. While it's still possible to change money, change it quickly! It's too late to wait until it's worthless at the end.
2. Nakamoto is the first person to discover bitcoin. Bitcoin is not issued by any institution, and the total amount is only 21 million yuan. The transaction of bitcoin needs the consent of 6 people!
3. Because bitcoin does not exist in the issuing institutions (bitcoin is extracted from the network), nor does it exist in banks, but directly through a personal to personal transfer.
4. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.
5. At present, it seems to be more insecure than the bank, whether it is stored on a computer or in a physical wallet, it is not as secure as the bank. Better for hackers to steal.
6. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis
above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

7. For more technical overview of betterhash protocol currently under development, it should be enough to see the speech of Matt Corallo. It is unnecessary to understand the problem of reprinting the theory of self fighting game network in this paper, because Conceptually speaking, betterhash is better objectively, and it does not need a complete code implementation to understand how important it is.
8. I have been in touch with Qian'an for a long time. In terms of ability, Qian'an is still very good. Its advantage is that it is the largest digital asset transaction in the world, and the best trading volume in 24 hours has exceeded US $10 billion. It's amazing to achieve such a performance in the instry.
9. There are many reasons for cell phone card crash, and the following two reasons are listed:
first, if the hardware is damaged, it may also cause frequent crash. Mobile phone is a precision electronic proct, and its circuit must work normally in a relatively stable environment. If the mobile phone often works in a humid environment or is strongly shocked by the outside world, It may crash.
for example, sometimes when we accidentally drop our mobile phone on the ground, it may crash. So we must treat our mobile phone kindly and handle it gently; Don't let the mobile phone get into the water, try not to use the mobile phone in the humid environment.
usually, if we operate the mobile phone improperly, it will also cause the mobile phone to crash. Especially when we are sending short messages, if the speed of key operation is too fast or we are bombarded by short messages continuously in a short time, the CPU load of the mobile phone is too large, and the heat generated by the CPU can't be emitted in a short time, Therefore, when we use the mobile phone, we must pay attention to the operation; Besides, try not to disclose your mobile phone number to avoid short message bombardment.
in addition, there are other factors leading to the crash e to hardware problems, such as the aging of hardware, the bad use environment of mobile phone, etc.
Second, software problems
are mainly caused by fatal bugs in the software design of mobile phone. For example, When the mobile phone runs a program, if there is a logic error between the subroutine and the main program, every time the mobile phone runs to the program, there will be an instruction error, which is a bit like the illegal operation in the computer. At this time, there may be a crash. The crash caused by the bug of the software generally has such characteristics: whenever it runs to a certain command, it will cause a crash, That is, every time you perform the same operation, there will be a crash.
if your mobile phone always crashes like this, it can be preliminarily determined that it is e to the software problem. To solve such a crash, you can generally upgrade the software. Now all major mobile phone manufacturers have customer service centers, which provide free software upgrade services, Such an upgrade can only upgrade the software version, and the function of the mobile phone will not change after upgrading. However, some software bugs are solved ring the upgrade, which reces the probability of crash. Now many DIYer mobile phones like to upgrade the software of the mobile phone, which causes instability to the mobile phone, so it's best to go to the customer service center to upgrade the software of the mobile phone, If you upgrade yourself, please make a backup in advance, so as to avoid the software can not be recovered after the upgrade failure.
in fact, the mobile phone crash is as normal as the computer crash. As long as we treat it correctly, there will not be so many people complaining about their mobile phone crash again. But if your mobile phone often crashes, you should pay attention to it, It's better to send your love machine to the customer service center for maintenance.
