Ⅰ 比特币期权怎么玩

不止1000倍吧？我体验过Bitoffer期权模拟，是2000倍都有了，因为比特币现价8000美金，开一张期权只要4美金就可以等同完全的一张比特币，相当于2000倍杠杆，风险最大为4美金

Ⅱ 比特币现金是否能超越以太坊呢匿

比特币和以太币规则不同，那么两者的交易和投资方式是否也有不同？一直以来，以太币都被称为比特币的有力竞争对手。直到AndreasAntonopoulos（《精通比特币》作者）声称以太币不再是比特币的竞争对手，这引发了社交网络上的激烈讨论。人们开始在两者之间做比较，讨论两种数字货币在投资和交易上有何不同。比特币以太币以太币的交易潜力ARK投资管理公司的分析员和区块链产品主管ChrisBurniske说，比特币地被用于保值，而依靠以太坊网络执行智能合约的以太币则地被视为一种交易工具。比特币和以太坊系统都是建立在区块链的基础之上的，其中的交易都会公开记录，货币及资产交易更加便捷优惠，去除了繁琐的中间人。2015年12月，以太币的价格不到1美元，如今已经涨到15美元，短短6个月就涨了将近15倍。这种成果归功于以太坊，它的金融合约完全依靠软件执行，这种特点吸引了大量用户进行投资。有了之前以太坊的例子，DAO（）的成功也就没什么好大惊小怪的了。这个由以太坊支撑的众筹平台从1万多个匿名用户处募资将近1.5亿美金。每个参与者都被赋予投票权，他们可以分配资金、选择项目，一旦投资的项目取得成功，还能得到一定程度的分红奖励。以太币和比特币的用户群不同目前世界上有670台比特币ATM机，成千上万的销售点支持比特币支付。与比特币不同，以太坊在电子支付领域还未崭露头角。以太币目前的主要用途是支撑起以太坊网络（比如DAO）来运行程序。StrengthinNumbersFoundation的执行董事DavidDuccini说：用户对以太币的期望与比特币有所不同。两种加密货币都可以进行投机买卖，但是以太币的原始功能是支撑应用程序运行。因此用户需要足够多的以太币运行自己的APP。这也是DAO面临的问题——除非DAO能够不断生成新的以太币，不然这个付费平台将面临停运的危险。

Ⅲ 比特币合约不亏钱的方法

任何投资风险与收益是并存的，如果你不想要风险，自然也没有收益。

Ⅳ 巴菲特为什么说比特币是泡沫

区块链技术自从出现后，除了一句“区块链是继互联网之后最伟大的发明”，让人们真正感到兴奋的不是技术的革命性，而是价格的剧烈波动，比特币已经从一项未来的技术变成了一个能一夜暴富的幻想。“股神”巴菲特也在最近表达了自己对比特币的看法：“你无法确定比特币的价格，因为这种资产不能创造价值??从这个角度来说，它就是个不折不扣的泡沫。”

比特币是一种全新的技术，是一种虚拟货币，它不像黄金一样具有存储价值，因为黄金是实际存在的，也无法被凭空捏造，所以黄金的稀缺性是确定的。但是比特币作为一种虚拟的货币而言，人们是有能力创造更多比特币的。比如之前疯狂的ICO。这就是一个对人性贪婪的考验，尤其是因为区块链去中心化的特性，让它处在一个不受监管的环境，难以像我们常规认知中的资产一样会受到法律或者某个权威监管。

虚拟货币是无形的，其背后的运作也是不透明的，但似乎投资者并不关心。尽管在几年前比特币还一文不值，但在今年12月初比特币的单价竟然突破过1.9万美元，约合人民币12万余元。而推动比特币不断上涨的最大原因就是越来越多接触过比特币的投资者害怕错过投资机会。

以太坊的联合创始人Joe Lubin曾经表示过“如果能够吸引足够多的人相信虚拟货币的价值，那么虚拟货币就能够快速让社会认可其价值。就像美元一样，美元的价值是基于人们对美国政府的信任。”但实际上美元作为货币是受法律、社会等监管的，换言之美元等传统货币是具有公信力的。而且数字货币的现金流最终来源还是货币持有者所付出的传统货币，所以Joe Lubin的看法是片面的。

人性的贪婪将比特币与区块链从一项革命性的技术，变成了一种单纯的投资手段，大家的身份也从“关注者”变成了“炒币者”。没有人再关心区块链技术的发展，这实际上是偏离了中本聪对比特币最初的愿景，即“点对点的电子现金系统”，其设计目的用于“支付”而非保值的“储备货币”。

狗狗币的联合创始人Jackson Palmer也表示过：“当你看到虚拟货币价格疯涨，最终这就是泡沫的体现，人们将会损失很多钱。”

比特币社区经过了激烈探讨，因意见分歧便诞生了为数众多的分叉，也就是IFO。其中最为著名的有比特币现金（BCH），比特币黄金（BTG）以及比特无限（BCX）。

比特币现金是比特币的首个分叉，被称为“比特币耶稣”的Roger Ver在过去几年中让比特币社区感到愤怒，因为其一直在支持受到争议的硬分叉。而另外一个合作人名为Calvin Ayre是一位亿万富翁，创立了一个互联网赌博和娱乐帝国。因为这二人的身份，让比特币现金出现的动机备受质疑。

另外，与比特币由一支比特币核心团队运营不同，比特币现金由多达7支的团队通过竞争来运营，而且其官方宣称BCH在发展过程中任何对其发展有利的人员和团队都可以加入到开发者序列中。BCH在未来有可能会遇到比比特币更大的分歧与动荡。

另外BCH为了解决交易速度问题，不惜牺牲中心化，莱特币创始人也抨击BCH仅仅是PayPal 2.0而已。而在BCH分叉后，Roger Ver也开始疯狂抨击比特币，无止境的为BCH背书。

而比特币黄金（BTG）分叉则是由香港挖矿公司LightningASIC主导，BTG完全没有解决比特币最为核心的扩容问题，区块大小维持在1M，仅仅是改变了挖矿算法，支持GPU挖矿，缺乏重放保护，并且采用了极不稳定的EDA紧急难度调整机制。BTG希望解决挖矿算力过于集中的问题，但是实质上其核心目的或许仅仅是为了用户能够更容易的挖矿。

而BCX则是与至今为止出现过的所有分叉都不同，首先其团队至今为止是完全匿名的，与上文其他两种分叉币亮明身份与其背后明显的动机不同，这支匿名的团队出现仅仅是希望"无妥协的实现中本聪的愿景"。

从官方给出的BCX特性来看，BCX是拥有目前最成熟，最全面的解决方案，并没有像BCH一样将区块直接扩大至8M，而是选择了更为成熟的2M大小来解决“区块过大导致出现孤块”的问题。难度调整直接选择DAA，避免了BCH所走的弯路。用户隐私保护也选择了目前更安全更完善的零知识证明。而闪电网络、唯一地址格式、重放保护等功能也都一并支持。

另外最关键的是BCX支持智能合约，并且在其官网专门讲解了智能合约的作用，可为数字资产的流通建立一个高效成熟的系统，并且可以在其链上支持各类应用，应用领域也极为广泛，例如版权、票据、支付、游戏、供应链、物联网等都可以在BCX链上实现。可见BCX的目的是为了真正的应用区块链技术帮助其他传统行业实现去中心化，实现中本聪愿景中的去中心化社会。

在理想与利益之间，可能绝大多数人都会选择利益，这在比特币社区里也毫不例外，不过这并不影响像BCX这样的极少数为理想而奋斗的项目。BCX到底能够有何作为，一起期待2018年1月15日BCX主网的正式上线。

Ⅳ 比特币支持智能合约吗

不支持比特币只能点对点传输目前

Ⅵ 智能合约是什么

智能合约"(smart contract)这个术语至少可以追溯到1995年，是由多产的跨领域法律学者尼克·萨博(Nick Szabo)提出来的。他在发表在自己的网站的几篇文章中提到了智能合约的理念。他的定义如下:
"一个智能合约是一套以数字形式定义的承诺(promises)，包括合约参与方可以在上面执行这些承诺的协议。"
让我们更加详细地探讨他的定义的意思。
承诺
一套承诺指的是合约参与方同意的(经常是相互的)权利和义务。这些承诺定义了合约的本质和目的。以一个销售合约为典型例子。卖家承诺发送货物，买家承诺支付合理的货款。
数字形式
数字形式意味着合约不得不写入计算机可读的代码中。这是必须的，因为只要参与方达成协定，智能合约建立的权利和义务，是由一台计算机或者计算机网络执行的。
更进一步地说明:
(1)达成协定
智能合约的参与方什么时候达成协定呢?答案取决于特定的智能合约实施。一般而言，当参与方通过在合约宿主平台上安装合约，致力于合约的执行时，合约就被发现了。
(2)合约执行
"执行"的真正意思也依赖于实施。一般而言，执行意味着通过技术手段积极实施。
(3)计算机可读的代码
另外，合约需要的特定"数字形式"非常依赖于参与方同意使用的协议。
协议
协议是技术实现(technical implementation)，在这个基础上，合约承诺被实现，或者合约承诺实现被记录下来。选择哪个协议取决于许多因素，最重要的因素是在合约履行期间，被交易资产的本质。
再次以销售合约为例。假设，参与方同意货款以比特币支付。选择的协议很明显将会是比特币协议，在此协议上，智能合约被实施。因此，合约必须要用到的"数字形式"就是比特币脚本语言。比特币脚本语言是一种非图灵完备的、命令式的、基于栈的编程语言，类似于Forth。

Ⅶ 比特币，区块链和ICO分别是什么有什么区别

比特币是中本聪于2009年提出的一种虚拟数字货币，特点是没有中心化的发行机构，总量固定，为2100万枚，而且不是一次性发行，需要由矿工挖矿产生。由于是去中心化的结构，信任就需要依靠密码学和共识机制技术来达到。
区块链是比特币衍生出来的一种通用技术，它实现了去中心化的数据库模型，比特币可以规为区块链1.0，因为它没有智能合约的概念。区块链关键技术就包括密码学加解密和共识机制，区块链一般是用来和具体业务逻辑相结合，这就需要依赖智能合约了，智能合约提供了不受人为干扰的执行模式。
ICO首次币发行，源自股票市场的首次公开发行（IPO）概念，是区块链项目首次发行代币，募集比特币、解决以太坊等通用数字货币的行为。

Ⅷ 比特币合约交易什么意思

合约交易是对比特币莱特币期货合约交易的统称。
2013年6月，796交易所在比特币业内率先开发出了比特币周交割标准期货—T+0双向交易虚拟商品作押易货合约（合约交易）。
合约交易的出现结束了此前比特币不能做空的历史，开启了比特币衍生品市场发展繁荣的序幕。

Ⅰ How to play Bitcoin options

Isn’t it more than 1000 times? I have experienced the Bitoffer option simulation, and it is 2000 times. Because the current price of Bitcoin is 8000 US dollars, it only costs 4 US dollars to open an option, which can be equivalent to a full Bitcoin, equivalent to 2000 times leverage, and the maximum risk is 4 US dollars< /p>

II Can Bitcoin Cash surpass Ethereum?

Bitcoin and Ethereum have different rules, so are their trading and investment methods also different? Ethereum has long been known as a strong competitor to Bitcoin. Until Andreas Antonopoulos (author of "Mastering Bitcoin") claimed that Ethereum is no longer a competitor of Bitcoin, which triggered a heated discussion on social networks. People started making comparisons between the two and discussing how the two digital currencies differed in terms of investing and trading. Bitcoin Ethereum Ethereum’s Trading Potential Chris Burniske, analyst and head of blockchain products at ARK Investment Management, said that Bitcoin is used as a store of value, while Ethereum, which relies on the Ethereum network to execute smart contracts, is considered a cryptocurrency. a trading tool. Both Bitcoin and Ethereum systems are built on the basis of the blockchain, in which transactions are publicly recorded, making currency and asset transactions more convenient and favorable, eliminating cumbersome middlemen. In December 2015, the price of Ethereum was less than $1. Now it has risen to $15, an increase of nearly 15 times in just 6 months. This achievement is attributed to Ethereum, whose financial contracts are entirely executed by software, a feature that attracts a large number of users to invest. With the previous example of Ethereum, the success of DAO () is not surprising. This crowdfunding platform powered by Ethereum has raised nearly $150 million from more than 10,000 anonymous users. Each participant is given the right to vote, and they can allocate funds, select projects, and receive a certain level of dividend rewards once the investment project is successful. Ethereum and Bitcoin have different user bases. There are currently 670 Bitcoin ATMs in the world, and thousands of points of sale support Bitcoin payments. Unlike Bitcoin, Ethereum has yet to make a name for itself in the field of electronic payments. The current main use of Ethereum is to support the Ethereum network (such as DAO) to run programs. David Duccini, executive director of the StrengthinNumbersFoundation, said: User expectations for Ethereum are different from Bitcoin. Both cryptocurrencies can be traded for speculation, but Ethereum’s original function was to power applications. Therefore, users need enough Ethereum to run their APP. This is also the problem facing DAO - unless DAO can continuously generate new Ethereum coins, this paid platform will face the risk of outage.

Ⅲ How to not lose money on Bitcoin contracts

Any investment risk and return coexist. If you don’t want the risk, there will naturally be no return.

IV Why does BuffettCalling Bitcoin a bubble

Since the emergence of blockchain technology, except for the sentence "Blockchain is the greatest invention after the Internet", what really makes people excited is not the revolutionary nature of the technology, but the revolutionary nature of the technology. With wild price swings, Bitcoin has gone from a futuristic technology to a fantasy of getting rich overnight. "Stock God" Buffett also recently expressed his views on Bitcoin: "You cannot determine the price of Bitcoin because this asset cannot create value?? From this perspective, it is an out-and-out bubble. ”

Bitcoin is a brand new technology and a virtual currency. It does not have storage value like gold, because gold actually exists and cannot be fabricated out of thin air, so the scarcity of gold is certain. But as a virtual currency, people have the ability to create more Bitcoins. For example, the crazy ICO before. This is a test of human greed, especially because of the decentralized nature of the blockchain, it is in an unregulated environment and is difficult to be supervised by law or an authority like the assets in our conventional understanding. .

Virtual currencies are intangible and the operations behind them are opaque, but it seems that investors don’t care. Although Bitcoin was worthless a few years ago, the unit price of Bitcoin exceeded US$19,000 in early December this year, which is approximately RMB 120,000. The biggest reason for Bitcoin's continuous rise is that more and more investors who have been exposed to Bitcoin are afraid of missing out on investment opportunities.

Joe Lubin, co-founder of Ethereum, once said, “If enough people can be attracted to believe in the value of virtual currency, then virtual currency can quickly allow society to recognize its value. Just like the U.S. dollar, the U.S. dollar The value of the U.S. dollar is based on people's trust in the U.S. government." But in fact, the U.S. dollar as a currency is subject to legal and social supervision. In other words, the U.S. dollar and other traditional currencies have credibility. Moreover, the ultimate source of cash flow from digital currencies is the traditional currency paid by currency holders, so Joe Lubin’s view is one-sided.

The greed of human nature has turned Bitcoin and blockchain from a revolutionary technology to a simple investment method, and everyone's identity has also changed from "followers" to "coin speculators" By". No one cares about the development of blockchain technology anymore, which is actually a departure from Satoshi Nakamoto’s original vision for Bitcoin, which was a “peer-to-peer electronic cash system” designed for “payments” rather than “reserves” to maintain value. currency".

Jackson Palmer, the co-founder of Dogecoin, also said: "When you see the price of virtual currency skyrocketing, in the end this is the manifestation of a bubble, and people will lose a lot of money."

After intense discussions in the Bitcoin community, numerous forks, namely IFO, were born due to differences of opinion. The most famous of them are Bitcoin Cash (BCH), Bitcoin Gold (BTG) and Bitcoin Unlimited (BCX).

Bitcoin Cash is the first fork of BitcoinRoger Ver, known as “Bitcoin Jesus,” has made the Bitcoin community angry over the past few years because of his support for controversial hard forks. Another partner, Calvin Ayre, is a billionaire who founded an Internet gambling and entertainment empire. Because of the identities of these two people, the motives for the emergence of Bitcoin Cash have been questioned.

In addition, unlike Bitcoin, which is operated by a Bitcoin core team, Bitcoin Cash is operated by as many as 7 teams through competition, and its official claim is that BCH has no influence on its development during the development process. Interested people and teams can join the developer sequence. BCH may encounter greater disagreements and turmoil than Bitcoin in the future.

In addition, in order to solve the problem of transaction speed, BCH did not hesitate to sacrifice centralization. The founder of Litecoin also criticized BCH as just PayPal 2.0. After the BCH fork, Roger Ver also began to criticize Bitcoin crazily and endlessly endorsed BCH.

The Bitcoin Gold (BTG) fork was led by the Hong Kong mining company LightningASIC. BTG did not solve the core expansion problem of Bitcoin at all. The block size was maintained at 1M, and it only changed the mining process. The mining algorithm supports GPU mining, lacks replay protection, and uses an extremely unstable EDA emergency difficulty adjustment mechanism. BTG hopes to solve the problem of excessive concentration of mining computing power, but in fact its core purpose may just be to make it easier for users to mine.

BCX is different from all forks that have appeared so far. First of all, its team has been completely anonymous so far. Unlike the other two forked coins above, the identity and obvious motives behind it are clear. Differently, this anonymous team only appeared in the hope of "realizing Satoshi Nakamoto's vision without compromise."

Judging from the official BCX features, BCX is currently the most mature and comprehensive solution. It did not directly expand the block to 8M like BCH, but chose to be more mature. 2M size to solve the problem of "too large blocks leading to orphan blocks". The difficulty adjustment directly selects DAA, avoiding the detour taken by BCH. User privacy protection has also chosen the currently safer and more complete zero-knowledge proof. Lightning network, unique address format, replay protection and other functions are also supported.

The most important thing is that BCX supports smart contracts and specifically explains the role of smart contracts on its official website. It can establish an efficient and mature system for the circulation of digital assets and can support various functions on its chain. Class applications, application fields are also extremely wide, such as copyright, bills, payment, games, supply chain, Internet of Things, etc., which can all be implemented on the BCX chain. It can be seen that the purpose of BCX is to truly apply blockchain technology to help other traditional industries achieve decentralization and realize the decentralized society in Satoshi Nakamoto’s vision.

Between ideals and interests, most people may choose interests. This is also true in the Bitcoin community.There are no exceptions, but this does not affect the very few projects like BCX that strive for their ideals. What exactly can BCX do? Let’s look forward to the official launch of the BCX mainnet on January 15, 2018.

IV Does Bitcoin support smart contracts

Bitcoin does not support point-to-point transmission at present

VI What is a smart contract

Smart The term "smart contract" dates back to at least 1995 and was coined by the prolific interdisciplinary legal scholar Nick Szabo. He mentioned smart contracts in several articles published on his website. The concept of contract. His definition is as follows:
"A smart contract is a set of promises defined in digital form, including an agreement on which contract participants can execute these promises. "
Let's explore what his definition means in more detail.
Commitments
A set of commitments refers to the (often mutual) rights and obligations agreed upon by the parties to a contract. These commitments define Understand the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods, and the buyer promises to pay a reasonable price.
Digital form
Digital form means that the contract must be written in a computer-readable format in the code. This is necessary because as long as the participants reach an agreement, the rights and obligations established by the smart contract are executed by a computer or computer network.
Further explanation:
(1 ) reaches an agreement
When do the participants of a smart contract reach an agreement? The answer depends on the specific smart contract implementation. Generally speaking, when the participants commit to the execution of the contract by installing the contract on the contract host platform, The contract is discovered.
(2) Contract execution
The true meaning of "execution" also depends on implementation. Generally speaking, execution means active implementation through technical means.
(3) Computer-readable code
In addition, the specific "digital form" required by the contract is very dependent on the protocol that the parties agree to use.
Protocol
The protocol is a technical implementation (technical implementation), on this basis On, the contractual promise is fulfilled, or the fulfillment of the contractual promise is recorded. Which agreement is chosen depends on many factors, the most important of which is the nature of the assets being traded during the performance of the contract.
Again, take the sales contract as an example. Assume that the parties agree to pay the price in Bitcoin. The protocol chosen will obviously be the Bitcoin protocol, on which the smart contract is implemented. Therefore, the "digits" that the contract must use"Form" is the Bitcoin Script Language. The Bitcoin Script Language is a non-Turing complete, imperative, stack-based programming language, similar to Forth.

Ⅶ Bitcoin, Blockchain and What are the differences between ICOs

Bitcoin is a virtual digital currency proposed by Satoshi Nakamoto in 2009. It is characterized by the fact that there is no centralized issuing institution, the total amount is fixed at 21 million, and It is not a one-time issuance, it needs to be mined by miners. Because it is a decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve.
Blockchain is a general technology derived from Bitcoin , it implements a decentralized database model. Bitcoin can be classified as blockchain 1.0 because it has no concept of smart contracts. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used To combine with specific business logic, this requires relying on smart contracts, which provide an execution mode free from human interference.
ICO initial coin offering, derived from the concept of initial public offering (IPO) in the stock market, It is the first time a blockchain project issues tokens, raises Bitcoins, and solves general digital currencies such as Ethereum.

ⅧWhat does Bitcoin contract trading mean?

Contract trading is a transaction on Bitcoin The collective name for Litecoin futures contract trading.
In June 2013, 796 Exchange took the lead in the Bitcoin industry to develop the Bitcoin weekly delivery standard futures-T+0 two-way trading virtual commodity pledged barter contract (contract transaction).
The emergence of contract trading ended the previous history of Bitcoin not being able to short-sell, and opened the prelude to the development and prosperity of the Bitcoin derivatives market.
