Leo's regulation kills off seat premiums, preventing everyone from seeing certain seats and then placing large orders of 100e, 200e the next day. Speculation isn't supposed to be done this way.

This is the internet trading strategy—seat premiums are too outrageous. When the龙虎榜 (Top List) appears, seats are immediately topped with 200e in a straight line, hitting multiple boards. All this money is earned by you, so how can you play like this?
So it's not that regulation is too random; it's targeting certain seats. Better to stay away from some seats for now.
