I still like the idea of keeping it free, but all the rules are open to discussion. The subforum for doing so is here... I don't know how to move this thread:
http://forum.coinfest.org/index.php?board=20.0I think this still might count as free attendance, though... It might be fine, unless somebody really doesn't have £1, maybe you could let it slide if that happens. It depends on how you got the paper wallets. If somebody gave them to you to give away, then that's not cool.
If you're basically selling them, though, converting their fiat to paper crypto, then I don't see the big deal. You're more like a vendor, at that point. They're allowed to make a small percentage fee in profit, even, to sustain themselves. Don't rip everybody off, though...
