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. Because most people do not have the courage and ability to challenge the strongest hegemonists in the world. Nakamoto also wanted to vent his anger before he created bitcoin, but something unexpected happened to him. He successfully challenged the hegemonists! But he was also afraid for various reasons and did not dare to go on the road any more. Nakamoto also came up with the idea of decentralizing money under the condition that the excessive issuance of coins led to the rapid shrinkage of personal income for many years. Bitcoin was just put forward by him, and was jointly completed by more knowledgeable friends on the Internet.
8. The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized
extended data:
characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center
in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

9. The design of "decentralization" determines that the "centralized" government cannot touch bitcoin
the emergence, development, amendment, circulation and extinction of bitcoin do not depend on the government, so "whether the government allows" has nothing to do with "whether bitcoin exists"
for example, the birth, development and extinction of the solar system do not need the permission of the government
if bitcoin is exchanged with the government controlled "legal tender" (such as US dollar), the government can influence the performance of bitcoin by controlling the legal tender
if the recognition of such assets reaches the bottom line of% 35 in 2019, the world pattern will be more reasonable, transparent and open
how should we deal with the coming risks- Buy bitcoin quickly to deal with the risk of "no bitcoin".
10. Litecoin is a kind of network currency based on "peer-to-peer" technology, which can help users pay to anyone in the world immediately. At present, lightcoin is the second
virtual currency after bitcoin in global circulation market value. The legends of bitcoin, Wright silver, infinite copper and pennies aluminum (Internet) are popular in the circle. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Litecoin is inspired by bitcoin (BTC), and has the same implementation principle in technology. The creation and transfer of litecoin is based on an open source encryption protocol, which is not managed by any central authority. Litecoin aims to improve bitcoin. Compared with bitcoin, litecoin has three significant differences. First, the liteoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the output of litecoin network is expected to be 84 million litecoin, which is four times the amount of currency issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in litcoin's workload proof algorithm, which makes it easier to mine litcoin on ordinary computer than bitcoin. Each litecain is divided into 100000000 smaller units, defined by eight decimal places. Lightcoin needs to be generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoin at one time. At present, the
computing power of lightcoin is growing rapidly, and miner can't dig mine through several computers. Therefore, it needs to be added to the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher. At present, the well-known
ore pools abroad include: wemineltc, coinotron, etc
