You need to make more clarification on your post, the title said win physical bitcoin and the post said it not physical bitcoin and we all know bitcoin does not have any physical representation of any kind. So how do you intend to give the winner the bitcoin are you going to transfer the equivalent of 1 bitcoin the the winner wallet?
To tell you honestly even if I am not that into it for example selling or buying, I read, view some of the topics here even @krogothmahattan have a thread or a raffle draw on it. AFAIK some of theme are pretty expensive yet the OP trying to give here is not that expensive maybe about just $10 if I'm not mistaken.
