Of course most airdrop is worth to join, forgetting the fact that scammers are gradually dominating the internet we still have some legit project but is very hard to find them, though there are some people who knows how to find a legit airdrop, sometimes I keep wondering how they manage to get them. what are the things that qualifies airdrop to be a legit one? Because i always make research before joining airdrop at first it will look very real but at the end it won't work out the Way I expected.
I am also in the same situation as you. I did a lot of research on legit airdrops but because I don't really understand the technical stuff I just tried to see the hype of an airdrop project. But even my friend who is experienced in airdrops also said that it is very difficult to find one that is legit. Like looking for a needle in a haystack. The most likely thing to do is try to sort the 10 or 20 best airdrops and consistently follow all their tasks.
