Airdrop option is essentially futile and worthless unless you are living in an area in which $5-100 dollars can make the world of a difference. Bounties on the other hand can provide more funds if you liquidate right away but they are still not a great amount of cash and again is only worth it if you live in an area which $100-$500 dollars can help you out per month. I wouldn't expect any more than that on either of those, and that might be a high range estimate but everything hinges on your rank here so take what I said with a grain of salt.
