You should! I couldn't believe how easy it was. It took like two hours of time to set up the node + lnbits + ssl certificate, and like ten minutes to print/apply the stickers. And the cost was super low -- $5 for the VPS, $2 for the foam and sticky paper, and I'm not sure how much the piñata costed (someone else got it) but it might even have been home made. (Piñatas are apparently very easy to make.) The only real cost was putting money in the qr codes, and even that was cheap, we decided on just $100 to fund them. Everyone can do this for any bitcoin-themed party!
