Airdrops

I’ve recently been looking into airdrops (which probably means it’s too late) and am wondering if these testnet challenges are worth it?

I’ve done several now, but from experience what are the odds of me receiving anything? Understand receiving something doesn’t guarantee it will be worth anything, but intrigued to hear others experience using test nets to farm airdrops.

I’m already skeptical as some a lot feel like scams to mine your data.

I don’t have much risk appetite so I’d prefer to complete any tasks at low to zero cost.
