I like bounty and Airdrop though I like bounty more than Airdrop. Yes it will take time for both parties to earn but I see bounties more fulfilling than Airdrops. Sometimes, I see them the same whenever I wait for the tokens and it's value and ofcourse the distribution, but bounties can give you much larger amount of money. What I like about Airdrops is that the tasks are easy and sometimes you can just register with your accounts and then you'll have to wait for the tokens, but it really takes a lot of patience to get the tokens. So I guess, I am seeing great deals with bounties than Airdrops.
