Isn't the key way too long to be for an address?
This is a good point and I would need to look into the code now to confirm or deny this. Good possible that you will only see a fraction of the wallet balance after importing the priv keys.
According to research someone (Daffy?) did a while ago the PC keys are not XPY addresses. They are private keys supplied to the wallet daemon via command line or config file and allow any address in that wallet to stake at the higher rate. That's all. No minimum balance requirement or anything like that.
So the key is a secret identifier like an ID string not a wallet address?
I thought you were part of this scam...you switched sides now? I have not been following this all that close so forgive my lack of following this.
