Both are the worst. Still, people earning from bounty and Airdrop? Isn't waste of time? I don't think Airdrop even gives you a return of your Internet bills lol. On the other hand, most bounty campaigns are scams. Either they don't pay or rug investors and hunters. Better learn something else and earn like trading and service. Nothing is free in the world. Don't run for free money, work hard and earn.
