Generally no, airdrops that tell you you will get 5$ are shit and will give you nothing. Look for some other, with several rounds, when you can get a huge amount of coins. But in those kind of airdrops you need to participate and do something for the community. Maybe you will get involved in it?

I personally recommend Privcy (PRIV) - there are still several rounds to come, the coin is pretty cheap right now but has a huge potential.
