This came up again: "but bitcoin is not 'real' like gold, why does it have value?"
If something is use by people, it has value. Many non-physical tools have value. Google, Facebook (& #bitcoin) don't have physical stuff, but people use it, so they have value. Utility value.
这一点再次出现：“但比特币不像黄金那样‘真实’，为什么它有价值？”
如果某样东西被人们使用，它就有价值。许多非物理工具都有价值。谷歌、脸书（Facebook）和比特币（bitcoin）没有实体内容，但人们使用它，所以它们有价值。实用价值。
