This is a very sad state of affairs. It will take a long time for the coin to recover when there is more airdrop coming.
Dev should consider slowing down the release of the coin. Large coin supply does not help
Large supply is good if dev team can create massive demand like XRP does ( around 37Billion circulating supply.
) and some other successful high-supply coins.
-devs transparency like interviews and stuff
-other potential devs joining the team
-in big exchanges for liquidity
-very active in social medias
-PR
-unique roadmap
-constant development
etc...
If you dont have that, 9B coins will just end up dumped below 10 sats, leave dev wondering why his coin cant even lift up.
