比特币最早多少钱一个

2009年比特币刚刚出现时，价格还不到1美分，一美元可以兑换1300个比特币，也就是说人民币7元钱就可以兑换1300个比特币。2017年5月5日，海外数字货币交易平台Bitfinex报价，比特币的盘中一度触及1700美元，约合11737元人民币。

In 2009, when Bitcoins first appeared, the price was less than a cent, and the dollar was worth 1,300 bitcoins, which means that the RMB 7 was worth 1,300 bitcoins. On May 5, 2017, Bitfinex, the overseas platform for digital currency transactions, offered $1,700 in Bitcoin’s plate, amounting to approximately RMB 11737.

比特币（BitCoin）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。

The concept of BitCoin was originally proposed by Nakamoto in 2009, designing the open source software to be released along with the P2P network on which it is based. Bitcoin is a digital currency in the form of a P2P. Point-to-point transmission means a decentralised payment system.

比特币经济使用整个P2P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。该货币系统曾在4年内只有不超过1050万个，之后的总数量将被永久限制在2100万个。

The Bitcoin economy uses distributed databases consisting of numerous nodes in the entire P2P network to identify and record all transactions, as well as cryptography designs to ensure the security of the money flow chain. The monetary system was only 10.5 million in four years, and the total number will be permanently limited to 21 million.

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，只要有人接受，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 currencies of most countries. Users can buy virtual items in bitcoins and, if accepted, in bitcoins for real-life goods.
