any news about the airdrop of the other half that it was supposed to happen for those who swapped?
No, cause DEX is not live yet

You can join Discord and read annoucements about it
Upon checking their Discord, I can't see any pertinent data about the other half that should be airdropped to people. Also, it appears that there's nothing there. The last announcement in their Discord channel was made last July and nothing followed it. Someone also asked if the coin is already dead because of inactive devs/mods in the said channel. It would really help if someone from the team would post something here to enlighten the questions of other people.
don't want to FUD but this smells a lot like a scam.
anyway I'd love to be surprised by some good news.
