Mining is not meant to be fun either, though dare i say it really is meant to be boring. anyhow, it’s very likely meant to be satisfying. That’s why it’s an afk activity, providing low income at actually low risk. it is literally the thing people do in the game, when they do something else. it only gets interesting, when you use several accounts. You’re mistaking the fun of doing something else as the activity itself, which is a pretty common mistake to make.
