Whether a paid community in the currency circle can be considered an IQ tax depends on what services this paid community provides.
For example, if a paid community provides various first-hand information, tutorials, internal tools, etc., helping members gain greater value, and the benefits members receive from this paid group are greater than the group fee, then this paid group is valuable.
If a paid group only contains various reprinted news, project advertisements, without any exclusive content, and the benefits members receive from this paid group are far less than the group fee, then this paid group is worthless.
The key to whether a paid community is an IQ tax depends on whether the group can provide real value to its members, rather than relying on hype to collect group fees. The best way to deal with this situation is to pay monthly or request a refund directly. Many airports that charge annual fees are prone to run away, but there is no need to worry about monthly payments. If a paid community supports monthly payments or refunds, it means that you don't have to worry about regretting it.
See what kind of value this group can provide you.
If the group has scarce resources, information flow, cooperation opportunities, and channels for sharing and communication, then it may be worth paying.
On the contrary, if the group does not have useful information and cannot provide value to you, then paying is just being a rogue~
