I would agree with Casascius coins or coins with a face value. The Nasty coins however are supposed keep growing balance wise. Had someone loaded 1BTC it would likely hurt, but .04 is nothing. How long would it take for one of these coins to actually earn .04? I would assume with seats costing a decent amount and the price of these new not too long?

tldr; tiny amounts of extra funding for these shouldn't matter.
