1. Print your bitcoin address as a QR code on a set of business cards (can get 250 cards for $10-$15 on iprint.com) along with the "Please send me 0.001BTC to this address" next to your QR code.
2. Get a pretty girl to hand out these cards to guys at a popular night club (either pay her or offer to split the proceeds with her).
creative idea but not one that is likely to work short term for sure.
first if you take bitcoins at lets say 700$ market price , that would make each 0.001 worth 0.70 .
to make back your initial investment of 10-15 you would have to get back in return 200 of the 250 cards sending you the 0.001.
in reality the rate of return of things like that(cards,matchbooks etc.) is under 10%.
now sure some might send you even more then the 0.001 but some may also send less too.
then you got to split with girl unless girl is you, or if girl is your girlfriend/wife in which then she gets all LOL.
overall i like the idea, but unless you get cards for free then its not really a great way to make bitcoins.
