I'm just a newbie and I don't have other opportunities to make money irl because of my place of living and age. I tried already bounties and airdrops, but I'm not lucky in it. Thanks for your advices!!!
To be honest, bounties and airdrops are a waste of time unless you're lucky enough to obtain a very nice one, which can be difficult to come by, that is why I don't do airdrops.
Yes, you are right, airdrops and bounties currently seem like a waste of time because most of them don't give any results, but there are still many who keep looking for them because they think maybe there will be luck that can give unexpected results.
OP seems to want to earn without capital and that is impossible in my opinion, even when we work in the real world there is capital that has to be spent such as transportation costs to get to work and also lunch at the office before finally getting salary.
It would be better for Op to increase skills so that they can be used to earn money and this still requires capital such as course fees to improve these skills as well as time.
