My apologies if this has been covered.
Can you send funds from a z address to a t address. I’m mining to my z address and would like to send to an exchange. Is there a disadvantage fee wise to be mining to a z address? Privacy is not a concern for me.
Also is there a command in the linux wallet to get the private key for my current addresses? It would be handy if at some point I would like to move my wallet to a new computer, OS, etc.
