I just join airdrop which evalued on icobench.com or icodrops.com, you should select here it is not waste your time.
I am not sure that all of the airdrops announced there are good verified. You can spend more time on research or join every airdrop and some of them will be successful.
A lot of airdrop hunters are too lazy to research and all they do is to join just any airdrop and you then see the likes of OP complaining that it sucks. I have joined some airdrops before that $10 turned to $1000 and still counting and holding since I believe in its future.
People do not always get the best when the only thing they do is never to be very skeptical of what they join. If you keep joining shitty project airdrop, then you should expect shitty coins or tokens and nothing else.
