1. The upper limit of bitcoin is 2100W, which is not up to the limit, but the cost is higher and higher. This kind of currency with a limit can slow down the depreciation of assets to a certain extent, just like gold. However, gold has value in use, while bitcoin is a virtual currency with no practical value, so this kind of currency is not as stable as gold (for example, bitcoin plummeted this time). Bitcoin can be split and purchased on some websites.
2. There is no unified organization between bitcoin and lightcoin. Their core organizations are bitcoin foundation and lightcoin foundation
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system. Lightcoin is an unsuccessful test of bitcoin, the ancestor of Shanzhai coin and the second largest cryptocurrency in the world.

3. No, I think it's a virtual currency. It has no limit. If it's a global virtual digital currency, it should be traded 24 hours a day, and there is no limit on the rise and fall.
4. The current price is 1715.14
compared with 1768.90 at the close of one week ago, bitcoin has decreased by 3% in the past week,
compared with 1564.0 at the close of one month ago, bitcoin has increased by 9.66% in the past month,
compared with 1373.4 at the close of three months ago, Bitcoin has increased by 24.88% in the past quarter
since the beginning of this year, bitcoin's price has suffered a setback at the beginning of the year, and it has experienced a roller coaster in March, and it has graally recovered slowly in the past three months. In the short term, e to the influence of the stock market, capital flows back to the currency market, which is good for bitcoin, but the short power is still strong, Bitcoin's biggest rise reached 42.34% and then quickly fell back, falling back to the market before the rise, which still exists in the short term. Therefore, short-term trading is more obvious, short-term risk is high, and long-term operation is recommended.

5. 2% up and down every day.
6. CPI index, the full name of consumer price index, abbreviated as CPI, is the relative number of price changes of a group of representative goods and services, reflecting the changes of consumer price level. It is usually used to observe the level of inflation
CPI increases too much, indicating that the economy is inflating, and the central bank will tighten monetary and fiscal policies, resulting in an uncertain economic outlook. Therefore, the index's excessive increase is often not welcomed by the market<
China's current CPI composition and weight ratio (of course, the weight will change with the economic development, and there are different pages in different regions)
1 food 34%
2 entertainment, ecation, cultural goods and services 14%
3 residence 13%
4 transportation and communication 10%
5 medical and health care personal goods 10%
6 clothing 9%
7 family equipment and maintenance services 6%
8 tobacco and alcohol At present, the CPI survey covers more than 50000 survey outlets in more than 500 cities and counties in 31 provinces (autonomous regions and cities) in China. The national survey system directly under the National Bureau of statistics adopts the direct survey method of fixed person, fixed time and fixed point. Nearly 3000 full-time price investigators go to different types and sizes of agricultural markets and stores to collect price information. For commodities closely related to residents' life and with frequent price changes, the price survey should be concted at least every five days to ensure the timeliness and accuracy of CPI.

7. 2015 is known as the first year of blockchain technology. Now, more than two years have passed since the bitcoin craze. People's enthusiasm for blockchain technology has not subsided. So, what is this mysterious blockchain technology
what is blockchain technology
in a narrow sense: blockchain technology is a kind of chain data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged in the way of cryptography
broad concept: blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
Renhua: blockchain technology is a way for the whole people to participate in recording. In the blockchain system, everyone's records can be recorded and distributed to everyone in the system for backup. Such a decentralized way greatly improves the system security< br />
What are the benefits of blockchain technology
1. Blockchain technology is highly reliable
the design of blockchain enables it to effectively prevent failures and attacks. Because a blockchain is shared by a group of open users, even if a single node in the blockchain network fails, it will not lead to the loss of information on other nodes, the rest of the participants can still operate as usual, and the transaction transmission on the blockchain will not be affected
2. Blockchain is transparent
the transparency of the blockchain is that any data updates on the blockchain will be synchronized to the whole blockchain, and any data records on the blockchain network can be queried at each node. Blockchain eliminates the asymmetry of data and improves the trust between network nodes< br />
3. The records stored on the blockchain cannot be changed
unless more than 50% of the nodes in the blockchain change the same record, all data cannot be changed. This reces the risk of fraud in the transaction. Moreover, the stored records have the characteristics of irrevocability. When new data is written into a block, the newly generated block will be copied to all blocks in the blockchain. This process is irreversible, so the blockchain has the characteristics of irrevocability. This improves the accuracy of the transaction, simplifies the data processing process, and reces the cost of keeping the original data and transaction traceability

8. The minimum unit of bitcoin is 8 digits after the decimal point. Generally, exchanges can buy 6 digits after the decimal point,
that is, the minimum number is 0.000001. You can try it
now all exchanges are absorbing new users, and the operation is relatively friendly

9. Bitcoin is an e-cash system based on peer-to-peer technology, which allows one organization to make online payment directly with another organization, without the need for an authoritative clearing organization in the middle
in the world of bitcoin, if you want to own bitcoin, you need to apply for a bitcoin address, just like when you deposit in a bank, you need to open an account, and then you have this account. With your own account, you can deposit to your account, and others can transfer money to your account, when you need to withdraw money or transfer money to others, You need to show a key that can open the address, which is your private key, just like you need to provide a password when you withdraw money from ATM
different from the legal tender issued by banks, the issue of legal tender is managed by central banks of all countries. We all believe that central banks are reliable, will not miscalculate accounts, and will not be attacked. However, the issuance of bitcoin does not need the authority of the central bank. It allows a transaction to be settled directly from one organization to another, which saves the settlement link of authority, improves the efficiency of transaction and settlement, and saves the cost of transaction, especially the cost of cross-border transaction
blockchain is composed of multiple blocks, each block is composed of block head and block body, each block head contains the meta information of the block, and also contains a pointer to the hash value of the previous block head, which is the key information to prevent the blockchain from being tampered with. The block contains the transaction information of bitcoin. The first transaction is a special transaction, which is the reward given to the mining node. This is the only way to generate bitcoin, that is, to issue bitcoin. The rest of the transactions are transfer transactions. Bitcoin is paid from one address to another, which is also the only way to realize the value transfer of bitcoin. In summary, there are only two ways of bitcoin: Mining and transfer. After bitcoin comes into being, it can only be transferred from one person to another, but can not disappear out of thin air. Moreover, the total issue amount of bitcoin is constant, with a total of 21 million. It is a kind of general currency.
