Hi gluedog, it seems to me like the main hold up here is finding an exchange willing to do the swap. I found this the other day on kryptono exchange I thought it might be of interest:

   
"We are happy to announce that the rewards for our XPX promotion are being distributed to the winners who actively traded XPX on Kryptono Exchange during the promotion period of June 25 to July 14, 2018.

Check your email this week to see if you are a winner. The bonuses will be credited directly to your account on Kryptono Exchange."

Maybe instead of doing the airdrop you could do something like the above promotion with one or both exchanges you are on. Just a thought. Anyway I'm sure guys will work out something. I still got my XBL.
