Haha, that works too, if you don't need your money right away. It's actually one of the many killer features of this blockchain that many people outside of here haven't figured out yet.

I'm going to do a post today that goes over how they work that hopefully is a little more helpful, but to answer your question, no you don't have to pay any additional fees, only the normal fees you would pay to use the network.

If you have any other cryptos that you're hodling, you definitely should be using a hardware wallet.
