I go for bounty based on my experience, I use the campaign to earn money because itis not too risku unlike to the investing, trading and etc. This is because I don't want to use a capital. Airdrop is one beneficial, when the time I wait my salary, the airdrop fill my needs, but I'm disappointed because myethetwallet was hack in airdrop, all my token was stole. They stole of almost $20k.
