the airdrop for me its super profitable to gained money, even its all free but you need also to support them, what i mean is if you buy some token or coin for better,. i know they dont yet if they success the project i just suggest its get to support them, even its small money you spend in that project but soon your spend money to his project your profit make 3x income.
yes everyone expectation is profit only but in sometimes it will not happening when you put 100% effort also so it is all about some luck also involved in the investment so profit is definitely possible in airdrops also but we need to pick the right one
