Well I did find a link to a telegram channel that post recent and updated airdops for free.
https://t.me/joinchat/AAAAAEbE47xLVW2WiUqjAThey send updates on airdrops and the ones I have participated in seems to be worth it. You should try jumping on this. I know how it feels like participating in airdrops that only become a waste of time at the end of the day, quite frustrating. This is why I don't just go for just any airdrop these days.
