He probably comes under that category of admin who has the resources and reach among people but doesn’t have the skill set to execute the assigned task. So, in that case its quite fair that he is hiring crypto traders to look after the group.

Although, I agree with your point that the people cannot be left hanging if something goes wrong. So, for such scenario he must have a backup trader ready who can resume the work if such situation is to occur. Anyways,I support your view that it would be quite better if he took the trade course and handled the group himself.
