2) some of my earlier payouts are market as "generated" in my bitcoin-qt wallet. https://blockchain.info/address/1KJaJktJ9q1M12McyYSLKXhaqyASGXS4S5 does that mean i earn the network fees produced by this coins? so does it make sense to throw them in the economy instead of holding in my wallet so they can produce fee for me? OR am i absolutely wrong? Please explain then.
