：比特币的挖矿收入和比特币的价格一样不稳定
规模化比特币挖矿有巨大的好处。在获得廉价的电力和数据中心的情况下，
开采加密货币可以获得利润。因此，挖矿大多已经超过了业余爱好者的范围。
新的加密货币宣扬欢迎业余矿工，但比特币已经到达了基于数据中心的大规
模挖矿的企业级水平。

区块的生成
为什么存在挖矿？许多加密货币之所以需要挖矿，是因为它们使用了一种叫
作工作量证明的共识算法（我们将在下一节讨论）。“工作量”的“证明”
是通过运行计算解决某个谜题（比特币的谜题是生成一个与特定模式相匹配
的哈希值），完成后就会显示出被挖矿的区块的地址。只有当前的谜题被解
决后，一个新的区块才会被添加到区块链中。
