In my opinion, Mod must have policy to make sure the price not down anymore. Day by day when amount of PRIV distributed, the price will have down step, 4 weeks ago, PRIV still have price 1000sts but now it just have 400-480 sts, and maybe with a lot of PRIV distributed from AD11 to A20, the price may be dump more than now. I think with people bought their PRIV, they can't join Airdrop anymore, because they are dumper, not a real holder
How would you keep people from selling what is rightfully theirs? We have unfortunately no influence on people that are willing to sell.
We can, of course, try our best to appeal to them by giving incentives, but it's not in our hand....
