I've seen many people complain that paid communities are just a way to scam newcomers. To be honest, I used to think the same. But from a different perspective, some people are indeed willing to spend money to shorten the gap in knowledge — this is not a waste, but using money to buy time and a sense of direction. Especially in the early stages of entering the industry, when the industry knowledge system is unclear, quickly understanding market logic through paid channels, avoiding common pitfalls, and then deepening one's understanding independently is actually a feasible approach. Of course, the prerequisite is having the ability to discern; don't just follow the crowd and pay blindly. I personally don't have the energy to do this, but that doesn't mean I deny others' choices. Everyone's learning costs and time value are different, so there's no need to generalize.
