Do you often participate in airdrops? What information will you care about? Is it on the exchange? What is the price of the currency? what is this else? What do you think the airdrop activities of the project are doing well?
Most of the coin in the market that gives out airdrops turns out to be shitcoin because any thing given out for free to people is not really valued by those it was given to, this is why it is good for them to carry out some task before the coin is being rewarded to them, and one thing you should know is that only 1 in every 30 airdrop that actually gets to pay you something reasonable when they get into the Crypto market so you just have to be ready to do trial and error to be able to earn from airdrop.
The way we have ICO projects that are bad is the same way we have bad airdrops, but it doesnt now mean that we still dont have the good ones, we have, and they are still quite much in the market.
It is just left to us to really develop a strategy that will help us in discerning projects that are good for us to participating in, instead of participating in them randomly and hoping that 1 out of the many we have worked on will work. We have to consider our time, because time is also an investment, this is why it becomes very necessary for us to really research on these projects before making any move on them.
