The bottom line is that I am a poor student with a small dream that requires an investment of money and time.
Your dream needs investment? Are you aiming for some entrepreneur like thing? I would suggest you to re-think your current position and focus on more studies and the mainstream market instead of crypto.
And it is very difficult to earn money during a pandemic and with living conditions in the village-like city.
But your "village" still has access to internet and electronic devices otherwise you would not be posting here. So I guess you can take in the forums campaigns that pay in bitcoin.
So I have a question. Is it realistic to make money on bounties and airdrops at the moment? How long will it take me, with my current status on forum, the lack of a three-digit number of subscribers on social networks and other experience. If possible, I would be very grateful for any advice, because I have no experience other than participating in airdrops in 2017.
Honestly speaking, No. You would be wasting time on them more than you can spend time to work on your studies and skills.
Bounties were good at one time back in 2017 and now they are nothing but shitcoins, failed teams forcing people to submit KYCs and plain scams being propagated like wildfire.
Its a vicious cycle of despair and frustration and trust me as a student you will not want to become a part of this.
What you can do is go for the bitcoin paying signature campaigns. They will be worth your time.
