Sorry about the inconvenience.
The update of masternode on the old chain database was not successful. We have to fork a new blockchain.
The coin on the exchange will be updated later, please be patient.
You can put the info in notes.
You can joined the discord group and ask for help.
https://discord.gg/K3U6r6JPlease swap early as the stake weight is low now.
Understand the concerns, but anyone can claim any address in the form and put a new address, how do you verify the claims?
Instead if you ask everyone to use the old wallet.dat files in the new wallet, then everyone will have the same address, so it will be easier for you to disburse.
BTW, who is the admin now to contact in Discord eighth8th#6042 or fiona13#2505
