TL;DR
You need to verify your ownership of the wallet address and provide a new Polkadot wallet address through system.remarkWithEvent on Polkadot.
Make sure first that the new wallet address provided has no issues and that you can connect it to pioneer.bit.country without any issues.
Send us the extrinsic hash on Subscan.io and submit a support ticket with that extrinsic hash.
Notes:
1.- The extrinsic must be sent from the Polkadot Wallet address you set as a Receive Address for $NUUM.
Open https://polkadot.js.org/apps/#/extrinsics, select Polkadot Network.
Select your old wallet address
Select extrinsic type is system -> remarkWithEvent
Enter the following message remark: I am having issues connecting this wallet address to pioneer.bit.country, please replace my eligibility with the following "Your new Polkadot wallet address here", so I can participate in the Odyssey True Pioneers Campaign.
Note: Make sure that the new wallet address has no issues being connected to pioneer.bit.country.
