Sorry but I don't get it. The metric you're using like Top XXXX adresses can't really work. By switching from fixed 10BTX to 2,5% you are just doing the same as before without needing the current big stakeholders to distribute their coins to many adresses, which wasn't very hard because of the currently low transaction fees.
In my opinion you don't need to change the kind of payout mechanism. There has to be change in how to determine the "winners", if your aim would be to broaden the userbase. Are you discussing this internally?
I am open for every fair solution.
Kind Regards Christian
You definitely need to decouple the airdrop from any blockchain based rich-list. It will always get gamed by the whales who were feed up even more in the two last air drops.
Alternative solution: Let every bitcointalk forum member with a rank higher than "Member" provide one airdrop address, and then "airdrop" 10 BTX to that address. (We will anyway not get more than 1000 user by this forum, so the airdrop should be smaller but fairer) This way you can more or less assure a fair distribution without concentration to whales.
Edit: The criteria could also be, that only an address with atleast 1 BTX coin inside is eligible for the airdrop, thus you can be sure that the person contributed to the coin either by
