A. 币圈和链圈的区别是什么

链圈”、“币圈”、“矿圈”不少人傻傻分不清楚，但撇开那些关联，三者的本质其实还是大相径庭的。在区块链生态中，目前大致划分为三个圈，分别为“链圈”、“币圈”、“矿圈”。三者相互关联，却也大有区别，
链圈——链圈，技术派的代表。门槛相较于其他两个圈更高，主要专注于区块链技术的发展与应用，所以对于普通人来说，比较难跨进去。
区块链可以分为三阶段：私有链、公有链和联盟链。
币圈——币圈，可以说是最丰富多彩的一个圈。专注于炒加密数字货币，为三圈中入门门槛最低的圈。主要特点为发币和炒作，基于区块链技术发行的币为主流币，如比特币、以太坊等，风险较小。而ICO发行的币，则为山寨币，存在一定风险，炒作则是因为行业缺乏监管，后台操盘常见造成，目前我国已禁止ICO。
矿圈——矿圈，是专注于“挖矿”的一群人所在的圈子。这个挖矿不同于生活中的挖矿，而是为了获得虚拟货币奖励所进行的一种行为，参与挖矿的人，则被称之为矿工。
挖矿需要借助工具，早期通过一般电脑即可挖矿，之后随着挖矿人数的不断增加，开始发展成矿机挖矿，矿池挖矿。挖矿所需付出的成本较高，比如耗电巨大，电费也是一笔不小的支出。
矿圈的门槛略高于币圈，但低于链圈。大部分人都听过挖矿，但真正参与挖矿的人还是较少。
而相比链圈和币圈，矿圈还会受到外部自然环境的影响，如矿场矿机遭到损坏等。
现在的大背景下，炒作区块链的概念已经毫无意义了。区块链从业者一定是要想办法为这个社会贡献价值，去创造财富，而不是蒸发财富，所以我们不区别币圈、链圈，能创造价值的就是好圈。

B. 币圈内的一些专业术语是什么

1、Blockchain——区块链

区块链是分布式数据存储、点对点传输、共识机制、加密货币算法等计算机技术的新型应用模式。是一个共享的分布式账本，其中交易通过附加块永久记录。

2、Block——区块

在比特币网络中，数据会以文件的形式被永久记录，我们称这些文件为区块。一个区块是一些或所有最新比特币交易的记录集，且未被其他先前的区块记录。

3、Node——节点

由区块链网络的参与者操作的分类帐的副本。

4、去中心化

去中心化是一种现象或结构，必须在拥有众多节点的系统中或在拥有众多个体的群中才能出现或存在。节点与节点之间的影响，会通过网络而形成非线性因果关系。

5、共识机制

共识机制是通过特殊节点的投票，在很短的时间内完成对交易的验证和确认；对一笔交易，如果利益不相干的若干个节点能够达成共识，我们就可以认为全网对此也能够达成共识。

6、Pow——工作量证明

Proofof Work，是指获得多少货币，取决于你挖矿贡献的工作量，电脑性能越好，分给你的矿就会越多。

7、PoS——权益证明

Proofof Stake，根据你持有货币的量和时间进行利息分配的制度，在POS模式下，你的“挖矿”收益正比于你的币龄，而与电脑的计算性能无关。

8、智能合约

智能合约是一种旨在以信息化方式传播、验证或执行合约的计算机协议。智能合约允许在没有第三方的情况下进行可信交易，这些交易可追踪且不可逆转。

9、时间戳

时间戳是指字符串或编码信息用于辨识记录下来的时间日期。国际标准为ISO 8601。

10、图灵完备

图灵完成是指机器执行任何其他可编程计算机能够执行计算的能力。

11、Dapp——去中心化应用

是一种开源的应用程序，自动运行，将其数据存储在区块链上，以加密货币令牌的形式激励，并以显示有价值证明的协议进行操作。

12、DAO——去中心化自治组织

可以认为是在没有任何人为干预的情况下运行的公司，并将一切形式的控制交给一套不可破坏的业务规则。

13、PrivateKey——私钥

私钥是一串数据，它是允许你访问特定钱包中的令牌。它们作为加密货币，除了地址的所有者之外，都被隐藏。

14、PublicKey——公钥

是和私钥成对出现的，公钥可以算出币的地址，因此可以作为拥有这个币地址的凭证。

15、矿机

尝试创建区块并将其添加到区块链上的计算设备或者软件。在一个区块链网络中，当一个新的有效区块被创建时，系统一般会自动给予区块创建者（矿机）一定数量的代币，作为奖励。

16、矿池

是一个全自动的挖矿平台，使得矿机们能够贡献各自的算力一起挖矿以创建区块，获得区块奖励，并根据算力贡献比例分配利润（即矿机接入矿池—提供算力—获得收益）。

17、公有链

完全开放的区块链，是指任何人都可读取的、任何人都能发送交易且交易能获得有效确认的、全世界的人都可以参与系统维护工作，任何人都可以通过交易或挖矿读取和写入数据。

18、私有链

写入权限仅面向某个组织或者特定少数对象的区块链。读取权限可以对外开放，或者进行任意程度地限制。

19、联盟链

共识机制由指定若干机构共同控制的区块链。

20、侧链

楔入式侧链技术（pegged sidechains），它将实现比特币和其他数字资产在多个区块链间的转移，这就意味着用户们在使用他们已有资产的情况下，就可以访问新的加密货币系统。

21、跨链技术

跨链技术可以理解为连接各区块链的桥梁，其主要应用是实现各区块链之间的Atom交易、资产转换、区块链内部信息互通，或解决Oracle的问题等。

22、硬分叉

区块链发生永久性分歧，在新共识规则发布后，部分没有升级的节点无法验证已经升级的节点生产的区块，通常硬分叉就会发生。

23、软分叉

当新共识规则发布后，没有升级的节点会因为不知道新共识规则下，而生产不合法的区块，就会产生临时性分叉。

24、Hash——哈希值

一般翻译做”散列”，也有直接音译为”哈希”的。简单的说就是一种将任意长度的消息压缩到某一固定长度的消息摘要的函数。

25、主链

主链一词源于主网（，相对于测试网），即正式上线的、独立的区块链网络。

对币圈“行话”还不了解的小伙伴，赶快来学习一下：

1、法币是什么？

法币是法定货币，是由国家和政府发行的，只有政府信用来做担保，如人民币、美元等等。

2、token是什么？

token，通常翻译成通证。Token是区块链中的重要概念之一，它更广为人知的名字是“代币”，但在专业的“链圈”人看来，它更准确的翻译是“通证”，代表的是区块链上的一种权益证明，而非货币。

Token的三个要素

一是数字权益证明，通证必须是以数字形式存在的权益凭证，代表一种权利、一种固有和内在的价值；

二是加密货币，通证的真实性、防篡改性、保护隐私等能力由加密货币学予以保障；

三是能够在一个网络中流动，从而随时随地可以验证。

3、建仓是什么？

币圈建仓也叫开仓，是指交易者新买入或新卖出一定数量的数字货币。

4、梭哈是什么？

币圈梭哈就是指把本金全部投入。

5、空投是什么？

空投是目前一种十分流行的加密货币营销方式。为了让潜在投资者和热衷加密货币的人获得代币相关信息，代币团队会经常性地进行空投。

6、锁仓是什么？

锁仓一般是指投资者在买卖合约后，当市场出现与自己操作相反的走势时，开立与原先持仓相反的新仓，又称对锁、锁单，甚至美其名曰蝴蝶双飞。

7、糖果是什么？

币圈糖果即各种数字货币刚发行处在ICO时免费发放给用户的数字币，是虚拟币项目发行方对项目本身的一种造势和宣传。

8、破发是什么？

破指的是跌破，发指的是数字货币的发行价格。币圈破发是指某种数字货币跌破了发行的价格。

9、私募是什么？

币圈私募是一种投资加密货币项目的方式，也是加密货币项目创始人为平台运作募集资金的最好方式。

10、K线图怎么看？

K线图（Candlestick Charts）又称蜡烛图、日本线、阴阳线、棒线、红黑线等，常用说法是“K线”。它是以每个分析周期的开盘价、最高价、最低价和收盘价绘制而成。

11、对冲是什么？

一般对冲是同时进行两笔行情相关、方向相反、数量相当、盈亏相抵的交易。在期货合约市场，买入相同数量方向不同的头寸，当方向确定后，平仓掉反方向头寸，保留正方向获取盈利。

12、头寸是什么？

头寸是一种市场约定，承诺买卖合约的最初部位，买进合约者是多头，处于盼涨部位；卖出合约为空头，处于盼跌部位。

13、利好是什么？

利好：指币种获得主流媒体关注，或者某项技术应用有突破性进展，有利于刺激价格上涨的消息，都称为利好。

14、利空是什么？

利空：促使币价下跌的消息，如比特币技术问题，央行打压等。

15、反弹是什么？

币价在下跌趋势中因下跌过快而回升的价格调整现象。回升幅度小于下跌幅度。

16、杠杆是什么？

杠杆交易，顾名思义，就是利用小额的资金来进行数倍于原始金额的投资，以期望获取相对投资标的物波动的数倍收益率，抑或亏损。

C. 币圈一般去哪个论坛

telegram，qq，weixin，巴比特论坛，推特，知乎、知识星球、贴吧。。。交流平台挺多的
1. 没有被证监会、银保监会认可的金融是不合法的。随着区块链的概念被提出，开始盛行，在中国就有比特币、莱特币、瑞泰币等，这些的收益被吹得神乎奇乎，听了的人都会眼红，新生幻想，殊不知这只是一个庞氏骗局，就会忽悠投资者请君入瓮，将投资者的资金骗进去之后就是一串数字，有的一买就狂跌，聪明的人还可以止损，有的买进开盘疯涨，投资者不断加入筹码，最终无法套现。
2. 中国对这一块属于灰色地带。中国的股市尚不发达，到现今上证指数也才3400点左右，和美国纳斯达克指数，的恒生指数比起来显得太少了，就连国家承认的交易投资市场都还处于成长阶段，新型的交易自然是不合法的，国家也在大力的监管金融交易市场，防止投资者上当受骗。
3. 收益被吹得过高。股神巴菲特的年收益率平均也才20%，为何只有这么一点，因为他懂得市场投资规律，第一是鸡蛋不能放在一个篮子里面，分散风险，第二是任何不符合常态的收益都是假的。就是收益过度的虚高，投资就是一串数字在跳动，没有监管的法律部门，它想怎么变化就能怎么变化，投资者只会被蒙在鼓里玩弄。
4. 一般一个在发行的时候是由一个团队或者公司发行的，发行数量和周期、方式在白皮书里会说明。比如V神的团队发布了eth，目前流通总数为1亿多一点儿，比特币总发行数量是2100万个等..
如果说可以操作币价或者一定程度上影响币价的人是庄家的话，只要有钱，那么你都可以通过交易所进行大量购买进行拉升在高位进行抛售收韭菜。那庄家就多了。
所以资金比较多的商人或者商人团体、持币比较多的账户持有者等
5. 比特币的总量为2100万个，2140年挖完，挖矿速度四年减半，目前，比特币已经开采了1300万多一点。比特币由一个叫中本聪的人发明创造，此人在2010年以后消失在了比特币圈，并没有人知道此人是谁。
显卡挖的是比特币，这个在以前以前是可以的，但是现在使用显卡挖矿几乎就没有收益，当然，如果你的电是免费的还可以。你说的显卡挖矿是比特币挖矿的第二阶段，第一阶段是使用CPU挖矿，就是普通的电脑。第二阶段就是你提到的显卡挖矿，俗称烧显卡。目前，已经入第三阶段的ASIC矿机挖矿阶段，这个阶段算力极高，挖矿收益很低，挖矿成本几乎接近甚至超过了币价。现在大型矿场挖矿盈利主要是靠矿机的耗能以及电价的优势
6. 币好是位于新加坡的一个，它和它的运营团队所坚持的是：严格的审核上币机制，只上有潜力的人气币。这个平台的团队，旨在为提供最佳的用户体验和资产提升的通道，它有这样的承诺，也确实这样做到了。

D. 币圈几大主要论坛

币圈几大主要论坛如下。
1、连锁英语协会，联营协会成立于2018年3月，是国内首家集优质币种数据分析、项目分析、信息传播、网络直播、社区运营、联营基金为一体的去中心化分布式联盟。品牌内幕评论：第一链是由链英文协会流行的，或者可以说是第一条使链英文协会。每个项目都会为一个社区带来火，一个社区造就一群人，一群人造就一个项目。相得益彰，相得益彰。
2、Th09club 09社区，Th09club 09社区，09起源于2009年纪念比特币的诞生。Th09club最初是由一群it极客和社区积极分子创立的。早期主要从事各大技术论坛和IT社区。 2019年11月，社区启动“文创计划”，旨在通过区块链赋能，探索亚洲古老的历史文化遗产，拯救一批濒临灭绝的文创产品。品牌内幕评论：09社区成员来源广泛，分布在各行各业，主要集中在区块链领域。其成员联合垂直多元文化创意和金融界的领导者。圈内多款币在09社区流行。这是一个非常值得注意的社区。
3、投币社区，币玩社区为区块链爱好者提供区块链、比特币（BTC）、数字货币领域的基础信息和行业资讯，包括比特币（BTC）行情、趋势、区块链研究等。品牌内幕评论：一个非常低调运营的社区，几乎找不到任何关于社区运营商的相关信息，属于默默发财的类型。这个社区的资料很多，更新也很及时。有时您可以从中获得一些高质量的内容。
4、元博士社区，币博士社区论坛提供最新的数字货币新闻、最可靠的加密货币滚币项目、最丰富的区块链投资经验和最新的区块链技术知识。致力于打造活跃的区块链和数字货币爱好者投资交流社区论坛。品牌内幕评论：符合区块链行业的特点，也是一个比较低调的社区，很难找到社区相关的信息。据知情人士透露，该社区的创始人来自技术背景。在为一个大市场赚到技术钱后，他成功登陆并低调经营。币博士的定位是论坛+新闻站，算是不错的入门级社区。
5.币源社区，Coinogo社区成立于2016年5月，是由多位大型跨国企业IT精英、数字货币资深玩家、区块链技术精英等多位数字货币与区块链一站式综合服务平台发起成立。互联网连续创业者。品牌内幕评论：一个看起来很高大上的社区，获得了2018年中国最具创新性的区块链社区品牌。在区块链领域，走正规军路线的社区很少。这个社区的特点是模拟交易，可以为新手提供一个接近真实的交易环境，尽可能降低入门成本，也是区块链领域的一个很好的入口。

I. 币圈最赚钱的都是一些什么人

1-鲸鱼2-专业炒币人士3-交易所内部人员4-炒币机器人玩家

A. What is the difference between currency circle and chain circle?

Many people are confused about "chain circle", "coin circle" and "mining circle", but aside from those connections , the essences of the three are actually quite different. In the blockchain ecosystem, it is currently roughly divided into three circles, namely the "chain circle", the "coin circle" and the "mining circle". The three are interrelated, but they are also very different. There is a difference,
Chain Circle - Chain Circle, a representative of the technical school. The threshold is higher than the other two circles. It mainly focuses on the development and application of blockchain technology, so for ordinary people, it is relatively Difficult to get into.
Blockchain can be divided into three stages: private chain, public chain and alliance chain.
Coin circle - the currency circle can be said to be the most colorful circle. Focus on speculation Cryptocurrency is the circle with the lowest entry barrier among the three circles. The main characteristics are currency issuance and speculation. Coins issued based on blockchain technology are mainstream currencies, such as Bitcoin, Ethereum, etc., with less risk. And those issued by ICO Coin is an altcoin, which has certain risks. The hype is due to the lack of supervision in the industry and common background manipulation. Currently, ICO has been banned in our country.
Mining circle - Mining circle is focused on "mining" A circle of people. This mining is different from mining in life, but an act performed to obtain virtual currency rewards. People who participate in mining are called miners.
Mining It requires the help of tools. In the early days, ordinary computers could be used for mining. Later, as the number of miners continued to increase, it began to develop into mining machine mining and mining pool mining. The cost of mining is relatively high, such as huge power consumption. , the electricity bill is also a big expense.
The threshold of the mining circle is slightly higher than that of the currency circle, but lower than that of the chain circle. Most people have heard of mining, but there are still fewer people who actually participate in mining.
Compared to the chain circle and the currency circle, the mining circle is also affected by the external natural environment, such as damage to mining machines in mines.
In the current context, the concept of blockchain is hyped It is meaningless. Blockchain practitioners must find ways to contribute value to this society and create wealth instead of evaporating wealth. Therefore, we do not distinguish between currency circles and chain circles. Those who can create value are good circles.< br />The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only approved "Blockchain Technology Professional" pilot workstation of the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" launched by the School Planning and Construction Development Center of the Ministry of Education of China. . The professional position is based on providing students with diversified growth paths, promoting the reform of professional degree research, production, and research integration training models, and building an applied and compound talent training system.

B. Some professional terms in the currency circle are What

1. Blockchain——Blockchain

Blockchain is a distributed data storage and point-to-point transmission , consensus mechanism, cryptocurrency algorithm and other new application models of computer technology. It is a shared distributed ledger in which transactions are permanently recorded through additional blocks.record.

2. Block——Block

In the Bitcoin network, data will be permanently recorded in the form of files. We call these files blocks. A block is a set of records of some or all of the latest Bitcoin transactions that have not been recorded by other previous blocks.

3. Node - A copy of the ledger operated by participants in the blockchain network.

4. Decentralization

Decentralization is a phenomenon or structure that must appear or exist in a system with many nodes or in a group with many individuals. The influence between nodes will form a non-linear causal relationship through the network.

5. Consensus mechanism

The consensus mechanism is to complete the verification and confirmation of transactions in a very short time through the voting of special nodes; for a transaction, if the interests are irrelevant If several nodes can reach a consensus, we can think that the entire network can also reach a consensus on this.

6. Pow - Proof of Work

Proof of Work refers to how much currency you get, depending on the workload you contribute to mining. The better the computer performance, the more money will be allocated to you. There will be more mines.

7. PoS - Proof of Stake

Proof of Stake, a system of interest distribution based on the amount and time of currency you hold. In POS mode, your "mining" The income is proportional to your currency age and has nothing to do with the computing performance of your computer.

8. Smart Contract

Smart contract is a computer protocol designed to spread, verify or execute contracts in an information-based manner. Smart contracts allow trusted transactions to be made without third parties, which are traceable and irreversible.

9. Timestamp

Timestamp refers to a string or encoded information used to identify the recorded time and date. The international standard is ISO 8601.

10. Turing completeness

Turing completeness refers to the ability of a machine to perform any calculation that any other programmable computer can perform.

11. Dapp - decentralized application

It is an open source application that runs automatically and stores its data on the blockchain in the form of cryptocurrency tokens. Form incentives and operate with a protocol that displays proof of value.

12. DAO - Decentralized Autonomous Organization

It can be thought of as a company that operates without any human intervention and hands all forms of control to a set of uncontrollable entities. Broken business rules.

13. PrivateKey - Private Key

A private key is a string of data that allows you to access a token in a specific wallet. They, as cryptocurrencies, are hidden except from the owner of the address.

14. PublicKey——Public key

It appears in pairs with the private key. The public key can calculate the address of the currency.Therefore, it can be used as a certificate of ownership of this coin address.

15. Mining machine

A computing device or software that attempts to create blocks and add them to the blockchain. In a blockchain network, when a new valid block is created, the system will generally automatically give the block creator (mining machine) a certain number of tokens as a reward.

16. Mining pool

It is a fully automatic mining platform that allows miners to contribute their own computing power to mine together to create blocks and obtain block rewards. And the profits are distributed according to the proportion of computing power contribution (that is, the mining machine is connected to the mining pool - provides computing power - obtains income).

17. Public chain

A completely open blockchain refers to a fully open blockchain that can be read by anyone, anyone can send transactions, and transactions can be effectively confirmed. People around the world can participate in system maintenance, and anyone can read and write data through transactions or mining.

18. Private chain

A blockchain where write permission is only for a certain organization or a specific few objects. Read permissions can be open to the outside world, or restricted to any degree.

19. Alliance chain

The consensus mechanism is a blockchain jointly controlled by a number of designated institutions.

20. Sidechains

Pegged sidechains technology will enable the transfer of Bitcoin and other digital assets between multiple blockchains. This This means that users can access the new cryptocurrency system while using their existing assets.

21. Cross-chain technology

Cross-chain technology can be understood as a bridge connecting various blockchains. Its main application is to realize Atom transactions, asset conversion, and partitioning between blockchains. Information exchange within the blockchain, or solving Oracle problems, etc.

22. Hard fork

The blockchain has a permanent divergence. After the new consensus rules are released, some nodes that have not been upgraded cannot verify the blocks produced by the upgraded nodes. Usually a hard fork happens.

23. Soft fork

When the new consensus rules are released, nodes that have not been upgraded will produce illegal blocks because they do not know the new consensus rules, which will cause Temporary forks.

24. Hash——Hash value

Generally translated as "hash", there are also direct transliterations as "hash". Simply put, it is a function that compresses a message of any length into a message digest of a fixed length.

25. Main chain

The term main chain comes from the main network (relative to the test network), which is an independent blockchain network that is officially online.

For those who don’t understand the “jargon” of the currency circle, come and learn it quickly:

1. What is legal currency?

Legal currency is legal tender, issued by the country and the government, and is only guaranteed by government credit, such as RMB, US dollars, etc.

2, what is token?

Token, usually translated as pass. Token is one of the important concepts in the blockchain. It is more commonly known as "token", but in the eyes of professional "chain circle" people, its more accurate translation is "pass", which represents the area. A proof of stake on the blockchain, not a currency.

The three elements of Token

The first is digital proof of rights and interests. The token must be a certificate of rights and interests in digital form, representing a right and an inherent and intrinsic value;

The second is cryptocurrency. The authenticity, tamper resistance, privacy protection and other capabilities of the token are guaranteed by cryptography;

The third is the ability to flow in a network, so that It can be verified anytime and anywhere.

3. What is position building?

Building a position in the 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.

4. What is stud?

Cryptocurrency stud means investing all the principal.

5. What is an airdrop?

Airdrops are currently a very popular cryptocurrency marketing method. In order to provide potential investors and people who are passionate about cryptocurrency with information about the token, the token team will conduct frequent airdrops.

6. What is lock-up?

Lock position generally means that after investors buy and sell contracts, when the market trend is opposite to their own operations, they open a new position opposite to their original position. Its name is Butterfly Flying Double.

7. What is candy?

Cryptocurrency candies are digital coins that are distributed to users for free when various digital currencies are first issued and ICO. They are a kind of momentum and promotion for the project itself by the issuer of the virtual currency project.

8. What is a break?

Break refers to falling below, and hair refers to the issuance price of digital currency. A currency circle break means that a certain digital currency falls below the issuance price.

9. What is private equity?

Cryptocurrency private 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 operations.

10. How do you look at the K-line chart?

K-line charts (Candlestick Charts) are also called candle charts, Japanese lines, Yin-Yang lines, stick lines, red and black lines, etc. The commonly used term is "K-line". It is plotted as the opening, high, low and closing prices for each analysis period.

11. What is hedging?

Generally, hedging is to conduct two transactions at the same time that are related to the market, opposite in direction, of equal quantity, and with profits and losses offsetting. In the futures contract market, buy positions of the same quantity but in different directions. When the direction is determined, close the position in the opposite direction and retain the positive direction to gain profits.

12. What is a position?

A position is a market agreement that commits to buying and selling the initial position of a contract. The person who buys the contract is a long position and is in a position to expect an increase;The contract is short and in a position to expect a fall.

13. What are the benefits?
