You can also sell 10% weekly, which even at current prices is a substantial amount of money for most people. If you sell your 10% during an increase in price you can easily surpass an average person's salary for making 10 posts on an online forum.

As far as just participating in the airdrop goes you can get by with far less effort than any student or mini job requires, while having the chance of making several times the amount of money of a full-time salary. And all that while providing support for a project that could easily make the lives of a lot of people far easier and more convenient.
