What if the cards had a little coupon to recieve 1 free hive-engine token or like 0.1 HIVE ? This way you can pick a really cheap hive engine token like LVL or something where you can give out like 1000 for less than 1 hive and really make them an interesting way to give someone crypto
they redeem it by making a comment taking a photo of the card in their hand with their user name written on it and post it and ask for the token :) could be a LEO coupon too
Not a bad idea at all, but I'm not the right person to discuss this with. You better share this at the original post so the organisation can see it 😁
