Some time I participated in Airdrops. But over time understood that it does not cost that. I did not receive payment for the spent time.
sorry to hear that you are not getting payment from the airdrop.I would suggest do airdrop from this site:
https://airdropalert.com/ its good site for doing airdrop.here you can get upcoming, ongoing and past aidrop list. also, they paid to the hunter. I also suggest you do airdrop from this forum altcoin bounty section.its also a good place to do some airdrop
Nowadays Airdrop is not worth it because mostly they are scam so I think its waste of time. Also Airdrop is not trustworthy because possible you be a victim of scam, its better to waste your time in participating in bounty and do trading or investing because there's possibility can give you good profit. Unlike to Airdrop you will get nothing and waste of your time only, so dont i suggest participate in bounty.
