You can earn bitcoins by providing a Bitcoin address. BitBin's ad revenue is shared based on the amount of hits your paste gets in comparison to all monetized pastes as whole.
This feature is NOT recommended to be used with private pastes, as it allows people to see your private pastes if they know what Bitcoin address you have used!
