掌握比特币-开始赚取比特币的指导: New Moon (Vampyre Ser.)
by Adidas Wilson 顺宏比特币是由名不副实的程序员或者一群程序员发明的一种加密货币和数字支付系统，名叫Satoshi Nakamoto。 它在2009年作为开源软件发布。 系统是点对点的，交易是直接在用户之间进行的，没有中间人。 这些交易由网络节点验证，并记录在称为区块链的公共分布式账本中。 由于该系统没有中央存储库或单个管理员，比特币被称为第一个分散数字货币。 比特币除了被创造为挖矿的奖励外，还可以在合法或黑市交换其他货币，产品和服务。 截至2015年2月，超过10万商户和供应商接受比特币作为付款。 根据剑桥大学2017年的研究报告，使用加密货币钱包的用户数量达到2.9-580万，其中大部分使用比特币。
