It is advisable to choose the one where there are no conditions to send your personal data and where you do not have to perform many tasks, because if you can earn it will be a maximum of $ 15-20 in the current situation.
I'm not fan anymore, that's just a small earning unlike in the past that we can even early over $1,000.
Maybe that was also affected with the market as airdrop is good when the market is bullish as there are many new investors that
will come to buy even without seeing a working product on the project. We cannot have that kind of earning now.
