比特币到底是什么 为什么要买比特币？

2008年，美国次贷危机，从而引发了波及全球的金融危机。因为美国政府可以无限增发货币，导致通货膨胀，因为美国占世界主导地位，相当于全世界都要给美国次贷危机买单，一个叫中本聪的密码学专家觉得很不合理，于是他死牢能不能有一种支付系统，没有中心化记账，大家都有记账的权利，货币不能超发，账本公开透明，十分公平，于是比特币就诞生了！

In 2008, the US subprime mortgage crisis triggered a global financial crisis. Because the US government can increase its currency indefinitely, leading to inflation, because the US dominates the world, amounting to the world paying for the US subprime mortgage crisis, and because a cryptographer called Nakamoto feels unreasonable, he can't afford a payment system without centralization, everyone has the right to keep a book, money cannot exceed it, books are transparent, books are fair, and bitcoin is born!

比特币的概念最初由中本聪在2009年提出，根据中本聪的思路设计发布的开源软件以及建构其上的P2P网络。比特币是一种P2P形式的数字货币。点对点的传输意味着一个去中心化的支付系统诞生。

The concept of Bitcoin was originally proposed by Nakamoto in 2009, designing the open-source software to be released along the same lines as the P2P network. Bitcoin is a digital currency in the form of P2P. The point-to-point transmission means that a decentralised payment system is born.

与大多数货币不同，比特币不依靠特定货币机构发行，它依据特定算法，通过大量的计算产生，比特币经济使用整个点对点网络中众多节点构成的分布式数据库来确认并记录所有的交易行为，并使用密码学的设计来确保货币流通各个环节安全性。对点对的去中心化特性与算法本身可以确保无法通过大量制造比特币来人为操控币值。基于密码学的设计可以使比特币只能被真实的拥有者转移或支付。这同样确保了货币所有权与流通交易的匿名性。比特币与其他虚拟货币最大的不同，其有限数量为2100万枚，且每四年产量减半机制，具有极强的稀缺性。

Unlike most currencies, Bitcoin does not depend on specific monetary institutions for distribution, which is generated by a large number of calculations, using distributed databases consisting of numerous nodes in the entire point-to-point network to identify and record all transactions and using cryptographic designs to ensure the security of all links in currency circulation. The point-to-point decentralization and algorithms can themselves ensure that artificial currency values cannot be manipulated by large quantities of bitcoins. The cryptography-based design allows Bitcoins to be transferred or paid only by real owners. This also ensures the anonymity of currency ownership and circulation transactions. Bitcoins, unlike other virtual currencies, have the largest number of 21 million, and the mechanism of halving production every four years is extremely scarce.

比特币可以用来兑现，可以兑换成大多数国家的货币。使用者可以用比特币购买一些虚拟物品，比如网络游戏当中的衣服、帽子、装备等，只要有人接受，也可以使用，也可以使用比特币购买现实生活当中的物品。

Bitcoins can be cashed and converted into the currency of most countries. Users can buy virtual items such as clothes, hats, equipment, etc. in online games, if accepted, and can use bitcoins to buy real-life items.

为什么要投资比特币：比特币一词由其英文名Bitcoin音译而来，是网络虚拟电子货币的代表。比特币没有物理形态，由网络节点的计算生成，它并不受任何国家与金融机构的监管。通俗的来讲，比特币是一种总量恒定 2100 万的数字货币，和互联网一样具有去中心化、全球化、匿名性等特性。假如你向地球另一端转账比特币，就像发送电子邮件一样简单，低成本，无任何限制。

Why invest in bitcoin: the word bitcoin is translated by its English name Bitcoin, a representative of virtual electronic money on the Web. Bitcoin has no physical form, is generated by network node calculations, and is not regulated by any country or financial institution. Generally speaking, bitcoin is a constant total of 21 million digital money, with decentralized, globalized, anonymous features like the Internet. If you transfer bitcoin to the other side of the planet, it is as simple, low-cost and without restrictions as e-mail.

比特币最早出现在2008年中本聪的白皮书中。当我们在我们电脑或者手机上安装了一个比特币钱包，那么它就会生成一个比特币地址。通过这个地址可以进行转账等交易。那么这个地址这个时候就相当于我们的邮箱账号。

Bitcoin first appeared in mid-2008 in a white paper by Bennett. When we put a bitcoin wallet on our computer or cell phone, it creates a bitcoin address. This address allows transactions like transfers. So this time it's the same as our mailbox account number.

比特币是区块链的第1个应用产品。而比特币网络也是一个公共的分布式数据库。而密码学确保了比特币区块链的完整性和时间顺序。而比特币地址与另一个比特币地址之间的转账。是比特币区块链里面的价值转移。

Bitcoin is the first application of the block chain. The Bitcoin network is also a public distributed database.

而比特币钱包保存着一份私钥。而私钥就是为每一笔交易签名，而签名也确保了这个交易是不可篡改的。而所有的交易都会在整个比特币网络广播。通常会在接下来的10~30分钟内通过挖矿，被整个比特币网络确认。

And the Bitcoin wallet keeps a private key. And the private key is a signature for every transaction, and the signature also ensures that the transaction is irrevocable. And all transactions are broadcast on the entire Bitcoin network. Usually confirmed by the entire Bitcoin network in the next 10-30 minutes through mining.

挖矿是将待处理的交易数据包含到整个比特币网络中。挖矿就是将一个数据按照非常严格的密码学规则打包到一个区块中。并且要通过比特币网络的验证。没有任何一个团体或者是个人可以控制整个链当中的部分内容。

The mining is to include the transaction data to be processed in the entire Bitcoin network. The mining is to package a data into a block according to very strict cryptography rules. It is to be verified through the Bitcoin network. No group or individual can control part of the entire chain.

比特币是一种用去中心化、全球通用、不需第三方机构或个人，基于区块链作为支付技术的电子加密货币。比特币是一种虚拟的数字货币。和所有法定货币不同，它不依靠特定货币机构发行，而是由网络节点的计算生成，谁都有可能参与制造比特币，并且可以全球流通。所以基于比特币的特点，很多投资者都选择把比特币当做避险的工具。

Bitcoin is an electronic encrypted currency with decentralized, global, non-third-party institutions or individuals, based on block chains as payment technology. Bitcoin is a virtual digital currency. Unlike all legal currencies, it is generated not by specific monetary institutions, but by network nodes, who are likely to be involved in the manufacture of bitcoin and can circulate globally.

所以比特币网络是非常安全的。这也是现在比特币极具价值的体现，所以也被称之为“数字黄金”。

So the Bitcoin network is very secure. And that's what bitcoin is now very valuable, so it's called "digital gold."
