Airdrops are still worth it, especially with the bull run coming. Projects that have been thought to be dead are starting to gain traction and new projects giving out semming low value tokens could be worth something significant in the near future. However, many of them are not encouraging, offering little to no value in the immediate /short term.
I don't remember any big payouts from airdrop recently. These payments are approximately at the same level of 5-10 dollars, and this money is not always paid. Therefore, even if the price increases significantly, these 10 dollars will still not increase many times. And given that the others did not pay at all, the average profit will be less than a dollar.
How much time does it took to collect the Airdrop worth of 10$ or so ? I think you need to work for at least 3 to 4 works on different social media or signature campaign and then you will get this amount. This is not worth it. Instead it is better to work on some other work than on this uncertain bounties.
