I think if you don't you are lazy enough, then you can go airdrop hunting. But as one have said, there's no good airdrop lately and others have turn in scam. But if you want to work your ass off  then join bounty because they really pay good at the end. The only catch is that you should join a ICO that is not a scam. Really hard to tell now which is not though because I've just seem a good ICO that didn't pay in the end because the hard cap was not reached.
