Discussion
Minikeys is interesting -- I'd think the collectible value of any of these coins not yet redeemed would still have a premium over the price of the bitcoin, and thus be unlikely demanded for redemption. Though, that said, I suppose a smaller code isn't limited to such limited run products.
Gonna give that a try!
