Awesome work dev. Regarding a third airdrop here's my suggestion:
The 3rd should be the final airdrop where POS is distributed per percentage of remaining Airdrop POS to rank holders (the percentages can be worked out differently, these are arbitrary figures) .
Rank.....................Distribution
Newbie.........................3%
Junior Member.............5%
Member......................10%
Full member................12%
Senior member............20%
Hero member..............24%
Legendary member......25%
Example: If 400k POS remain for airdrop, after the sign up for the 3rd round:
legendary members receive (0.25*400000)/(No of Legendary members)
and so on...
Edit: Or you can also introduce a factor system per rank.
Well, I agree devs should consider an option of all remain coins distribution but probably in some other way. You want to give 50% of all coins only to Legendary and Hero members, that's too much. A lot of coins will be in the hands of minority. I think the better option is to distribute tokens based on the amount of coins person is holding at the moment of distribution. In such a way people, who don't sell their coins would be rewarded.
