I have a NEM nanoWallet with enough XEM to start harvesting. Do I have to pay the importance transfer transaction fee each time I start/stop harvesting or switch supernodes?
EDIT: Another question: Does it matter which supernode I join (I mean, does it matter if I choose the one with IP from my country or somewhere else)? Is one supernode better than another? I am assuming the nodes on the list to which I am able to join are all active.
