It is true that those legit participants earn the profits they don't deserve because of the new participants. But still we can't stop them if they also want to earn profits. I think if we add up another new rules and regulations, those legit participants will also suffer from it. I believe earning merits not easily is enough to limit everyone to rank up and earn a lot. So lucky those who have already a higher rank, but that only means that they are the real early participants here.
