As a territory founder, if i chose to not link an external wallet, I could just keep cowboy credits earned from zaps and stacker rewards, on the site to send to others and use for fees, zaps, etc. And I could also still receive some real sats from territory rewards that could be withdrawn to a wallet. So territory awards could still be custodial real bitcoin available to withdrawal on lightning? Is that correct? And if that is correct I guess I would have a cowboy credit balance and a Satoshi balance?
