Running a bounty can't be cheap. For every person participating you have to pay a fee. For telegram and airdrops, how do the devs afford it?

10k airdrops at 1 cent is $100 just for one round. That sounds costly to me. I also doubt a transfer would be so little as 1 cent.

What makes me wonder even more is how do devs that give up on their projects or let them die still pay out their bounty? Some scams even payout their scam coin which must cost them 100s of $$

Is there something I am missing? is mass sending eth tokens cheaper then I think? Maybe someone with some experience in send to multiple eth addresses knows. You also need to use a special service or have the know-how to send to multi addresses as well.
