The way ethan has it set up is that it dynamically averages the costs of the most recent few blocks to ensure that the transactions will process in something like like the next 3 blocks (i don't know the algorithm he uses exactly). This significantly reduces the risk of causing a backlog of transaction trying to move off the wallet.
Hello rawdog, is ethan have spare time to look into my account?. I'll send you my account's details and withdrawal address that I fill in the site. I don't have control of my wallet so I cannot use it to set up my account in case I forgot my password. Please let me know if you have time to ask ethan.
Can you login at the moment? If you can, I think you can change your master address.
From what you say "in case I forgot my password", so I assume that you are still able to login into your account.
If I were you, I would prefer to use the way of login using username and password than using the master address.
Username and password combined with 2fa is easier than using master address where you need to sign a message.
