I think you are anger because of your old XDN can't be swapped, but I agree with you. Actually, you are not alone, I'm buying XDN same years with you, of course till today I wish can be going at least same as the price I bought in the past. But maybe it will take more time. I kept my XDN on exchange, and never login again for a long time, I don't know that exchange still supported XDN or not, since my XDN buying because of profit from airdrop, I will not thinking too hard about this coin.

In other side, this is also your mistake doesn't follow developer updates on the discord or other community group. Or you are following them but doesn't care with their update. Swapped coin happens in several coins or token, if you are missing time to swapped, they will do same thing, will not allow holder to asking about swapping their coins.
