Bitcoin cuts meat
blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp
time stamp refers to the string or encoding information used to identify the recorded time and date. The international standard is ISO 8601
Turing completion refers to the ability of a machine to perform calculations that any other programmable computer can perform DAPP decentralized application is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of cryptocurrency token, and operates with protocols showing valuable proof Dao, a decentralized autonomous organization, can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules13. Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key
is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network
for those who don't know the "jargon" in the currency circle, let's learn it as soon as possible:
1. What is legal currency legal currency is legal tender, which is issued by the state and the government. It is only guaranteed by the government credit, such as RMB, US dollar and so on 2. What is a token token, usually translated into token. Token is one of the important concepts in blockchain. Its more well-known name is "token". However, in the view of professional "chain circle" people, its more accurate translation is "token", which represents a proof of rights and interests on the blockchain, rather than currency token one is digital proof of rights and interests, which must be in the form of digital certificate of rights and interests, representing a right, an inherent and intrinsic value
3. What is warehouse building
the establishment of a position in a currency circle is also called opening a position, which refers to a trader's new purchase or sale of a certain amount of digital currency
What is Sohasuoha refers to investing all the principal
What is airdrop
airdrop is a very popular marketing method of cryptocurrency. In order to let potential investors and cryptocurrency enthusiasts get token related information, token teams often air drop tokens
6. What is lockup position locking generally refers to investors opening a new position opposite to their original position when the market moves in the opposite direction after the sale and purchase contract, which is also called lock, lock order, or even butterfly double flying doughnut candy is a kind of free digital currency issued to users when all kinds of digital currencies are just issued in ICO. It is a kind of momentum and publicity of the project itself by the issuers of virtual currency projects
breaking refers to falling below, and issuing refers to the issuing price of digital currency. Broken currency circle refers to the price of a digital currency falling below the issue price
What is private placementprivate placement is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operation
What do you think of the K-line diagram
K-line chart is also called candle chart, Japanese line, yin-yang line, bar line, red and black line, etc., commonly referred to as "K-line". It is based on the opening price, the highest price, the lowest price and the closing price of each analysis cycle
What is hedging
General hedging refers to two transactions which are related to the market, opposite in direction, equal in quantity and balanced in profit and loss. In the futures contract market, buy the same number of positions with different directions. When the direction is determined, close out the positions in the opposite direction and keep the positive direction to make profits

What is reboundthe phenomenon of currency price rising e to rapid decline in the downward trend. The recovery is less than the decline
What is leverage
leverage trading, as the name suggests, is to use small amount of funds to invest several times the original amount, in order to obtain multiple returns or losses relative to the fluctuations of the investment object
The decline and rise of bitcoin are normal phenomena, because it is a kind of virtual currency. Since it is a virtual currency, it is bound to rise and fall, just like stocks. Personally, I don't think it's cutting leeks, because bitcoin is a virtual currency. As we said earlier, there are ups and downs. This is the law of development of things
bitcoin is like this. We should understand it first, and then make a judgment. This is the most important thing. The learning before the exam is the judgment, and the result of the exam is the gain. And those who have not learned, of course, can not enjoy themselves, so I personally think the crazy fall and rise of bitcoin is a normal phenomenon. Of course, this is only my personal understanding, not the public opinion
in June 2013, 796 exchange took the lead in developing the bitcoin weekly delivery standard Futures - t + 0 two-way trading virtual commodity barter contract (contract trading) in the bitcoin instry
the emergence of contract trading ended the previous history that bitcoin could not be short, and opened the prelude to the development and prosperity of bitcoin derivatives market

I think some people might give up. But on the whole, I won't give up. How far can bitcoin go? It's hard to say. There are too many unknowns. You have invested in so many costs. Although you can stop losses in time if you give up now, some small investors may give up, but it is impossible for large investors. Because stop loss can't stop that much. In addition, although bitcoin has plummeted, the confidence of the masses in it has not completely collapsed. After all, bitcoin was very brilliant at that time. After the crash, many people believe it will rebound{ RRRRR}
I feel that bitcoin has a long way to go. The future market is full of uncertainty. How can bitcoin survive and go further. We need to think it over
stop loss after the end of February 2020, the bitcoin market will graally form a symmetrical triangle. This is a common finishing form in technical analysis. The upper limit is downward inclined line and the lower limit is upward inclined line if the price goes up and breaks through the resistance line, it is a bullish signal; On the contrary, if the price falls below the support line, it is a bearish signal. After the price of bitcoin broke through the support line at the end of February, it actually indicated that the bitcoin market entered a downward trend at present, bitcoin has entered the downward channel. If bitcoin investors still hold the expectation that "half market price will bring bitcoin price rise", they will face greater market risk in the future and should stop loss in time extended data: bitcoin generation: in addition to packaging the received transaction information into data blocks, each data block will be allowed to issue a certain number of new bitcoins to motivate the miners who successfully discover data blocks. The bitcoin system determines the number of bitcoins to be issued according to the predetermined rhythm of additional currency issuance. If there is a service charge for other payment transactions, the miner will also receive a service charge since the miner can decide whether to package a transaction data into a data block, the miner may give priority to the transaction with higher handling charge. The block generation rate is expected to be one every 10 minutes, but the number of new bitcoins issued in each block cannot exceed 50, and this number will be halved every four years, so the total number of bitcoins will not exceed 21 million with the decline of the number of new bitcoin issues, handling charges will become the main motivation for mining. And that number is halved every four years. Users who put their computer resources into bitcoin mining activities in the earlier period are much easier to get bitcoin than miners who joined later the main reason for this design is to ensure that in the early development stage of bitcoin, enough computing power can be attracted to process data blocks. In fact, if no one digs, the initial trading activities of bitcoin will not be handled, and the bitcoin economy will stop in December 2012, the number of bitcoins was halved for the first time, which should be around July 16, 2016. At present, more than 15 million bitcoins have been g up. Because the total amount of bitcoin is limited, and the loss in circulation, bitcoin is a deflationary currency, and the current global market price is about 4.5 billion US dollars as for the fixed total amount, bitcoin has a lot of room for appreciation. If everyone uses bitcoin, the consequences can be imagined simply speaking, the generation of bitcoin is that the designer uses the concept of human digging for gold, uses a specific algorithm, calculates through the computing power of the computer, and obtains bitcoin. This method is also called "mining" on the Internet in order to maintain the normal operation of the system permanently, "miner" will also receive a certain amount of handling fee when receiving the transaction confirmation information, and "miner" can also freely choose the transaction with high transaction fee to package. At present, the global computing power has reached 1000p
for all the things traded, some people buy and some people sell, the number of people who buy will rise and the number of people who sell will fall
and the person who bought one minute before may want to sell one minute later, and the person who sold one minute before may want to buy one minute later
because who among the holders can accurately predict whether it will rise or fall
if you can predict that it will keep falling, why do you buy it? In fact, many retail investors are reluctant to cut their losses when they fall below the cost price. It is very common for them to drag on for two or three years
you should not think that you are smarter than others, even if you are willing to cut the meat, if you rebound immediately after cutting the meat, you will be slapped on both sides< In a word, no one can predict what will happen in two years.
only a few people make money by playing bitcoin. Most of them are either covered with quilts or cut their flesh and go away, becoming leeks. But most people who invest in the long run make money. Because the price of bitcoin is rising on the whole. It's not easy to count how many people make money
