什么是BTC比特币

比特币，全名为Bitcoin，是一种数字货币。它不像传统纸币那样由中央银行发行，而是由网络上的用户相互之间流通交易。比特币是2009年由中本聪所创建的一种虚拟货币，其独特性在于其技术特点——区块链。

Bitcoin, known as Bitcoin, is a digital currency. It is not issued by the central bank, as traditional banknotes do, but is a transaction between users on the network. Bitcoin is a virtual currency created in 2009 by the middle-bones, and its uniqueness lies in its technical feature, the block chain.

区块链是一种加密技术，用于记录和验证交易的公共数据库。通过节点到节点的连接，去中心化的方式维护了一个共识的账本。

Block chains are a public database for recording and validating transactions.

比特币的交易信息或用于其他数字货币的信息存储在分布式的区块链数据库中。区块链的最初功能是记录每一笔比特币交易，但现在区块链已经被用于众多场合，如智能合约、身份验证等等。区块链的优势是数据的不可篡改、去中心化、防止伪造等。

Bitcoin transactions or information for other digital currencies are stored in a distributed block chain database. The initial function of the block chain is to record every bitcoin transaction, but the block chain is now used on many occasions, such as smart contracts, identification, etc.

比特币是一种去中心化的电子现金，其运作模式是在全球范围内建立对等网络。每个人都可以通过运行自己的比特币软件来参与这个网络，这使每个人成为比特币网络的一部分。

Bitcoin is a decentralised e-cash that operates through a global peer-to-peer network. Everyone can participate in this network by running their own bitcoin software, which makes everyone part of the Bitcoin network.

比特币的交易是通过区块链数据库存储和验证的。一旦数据被记录在区块链上，便不能被更改或删除，因此可以保证比特币交易的安全性、可追溯性。在这个网络上，交易是由矿工完成的。矿工通过解决数学难题来验证交易，确定新的区块并将其添加到区块链中。解决问题可以得到比特币奖励，这也是矿工参与比特币网络的动力所在。

Bitcoin transactions are stored and validated through a block chain database. Once the data are recorded on the block chain, they cannot be altered or deleted, thus ensuring the safety and traceability of the bitcoin transactions. On this network, the transaction is done by miners. Miners verify the transaction by solving mathematical problems, identifying new blocks and adding them to the block chain.

比特币的供应是有限的，只能通过挖矿或购买来获取。挖矿是指计算机通过完成一定的算术难题来验证交易并发现新的比特币。随着时间的推移和日益增加的算力，挖矿日益困难，一般人难以通过挖矿方拿到比特币。因此，目前最为普遍的方式是购买比特币。有许多数字货币交易平台供应比特币的购买、交换和交易。

The supply of bitcoins is limited and can only be obtained by digging or buying them. Mining means that computers verify transactions and discover new bitcoins by completing a certain number of arithmetic difficulties.

优点：首先，比特币最大的优点是去中心化，没有中心化机构控制，用户可以完全掌控自己的比特币。其次，交易记录不可篡改，可追溯，保护交易的隐私性。其次是去除银行等中间商的手续费，提高了效率。

Advantages: First, Bitcoin has the greatest advantage of decentralizing, without centralized institutional control, that users can fully control their own bitcoin. Second, the record of transactions cannot be tampered with, retraceable, and protect the privacy of transactions. Second, removing the fees and fees of middlemen, such as banks, improves efficiency.

缺点：首先是价值波动性大，价格波动大，价格难以预测。其次是风险，一旦私钥丢失或被盗，比特币无法找回。另外，虽然比特币流通量有限，已经达到了2100万的上限，但是市面上依然有许多其他的数字货币，竞争十分激烈，风险很大。

Weaknesses: First, high value volatility, high price volatility, and unpredictable prices. Second, risk is that Bitcoin cannot be recovered once a private key has been lost or stolen. And, while Bitcoin circulation is limited and has reached its upper limit of 21 million, there are many other digital currencies on the market, with intense competition and high risks.

比特币的未来前景依然很大。区块链技术的逐渐成熟，使得数字货币能够成为一种安全、快捷、大范围可用的支付手段。比特币的优点越来越被人所知，有越来越多的用户加入比特币网络。同时，其他数字货币也在市场中涌现出来。虽然比特币面临着一些挑战，但具有其本身的优势和未来前景对于比特币来说，未来是值得期待的。

Bitcoin’s future prospects remain high. The growing maturity of block chain technology makes digital money a safe, fast, and widely available means of payment. Bitcoin’s advantages are increasingly known, and more and more users join the Bitcoin network.

比特币是一种数字货币，通过区块链技术运作。它的去中心化、不可篡改的特性使得它的安全性和可靠性得到了广泛认可，且具有普遍的可用性和可支付性，因此越来越多的用户加入比特币网络。虽然比特币仍然存在一些挑战和不足，但其优点让我们对它的未来充满期待。

Bitcoin is a digital currency that operates through block chain technology. Its decentralized, non-alterable character makes its security and reliability widely recognized, and its universal availability and affordability make it possible for more and more users to join the Bitcoin network.
