我不支持开收费班、收费群，因为这和V4V理念互斥，英语社区的bitcoiner一般都践行V4V理念，解释一下V4V，转自 https://dergigi.com

The idea of value for value is simple: information is provided free of charge, directly, without any paywalls or middlemen. If the information was valuable to you, you are encouraged to give value back.

所以你会看到，有的bitcoiner开知识星球，而有的不开。
