Exactly! There are some interesting projects out there. And it also depends on how greedy and lazy one is.
I don't mind filling some forms and do few tasks to get coins/$. Also, for a simple airdrops it doesn't take more than a minute or two. The last airdrop I'm in (more like sig. campaign) - I maybe spend 10 min a day for it.
For me, it's worth it.
There are also regular airdrops on one exchange, I literally need to spend 10 seconds for it. Retweet and send a screenshot in a form. How hard can it be?
And don't even let me start on Ontology or maybe (fingers crossed) Dfinity.
Of course there are some scams, but people, use your brain. If it's too good to be true, than probably is.
And think twice when they ask KYC for 10$.
