Just google bro. There are so many website that are providing a lot of airdrops every day. Moreover, there are telegram groups that are posting 10-20 airdrops every day. Just find a trusted website and take part in airdrops 
I think instead of searching in Google, you can use the search tool in this bitcointalk forum to find airdrop in Bounties section. But I think the airdrop now is not able to make money. Just find the giveaway of the token in bounty ICO project and register to receive a lot of tokens.
