Most of airdrops are dumb, that thing itself deprecates the value of the coin, so in the end, any airdropped coin will not be worth much. I'd recommend you to learn to trade or to do long-term investments.
There's two case of successfully coins that before had airdrops.
Nano
Byteball
Both of them are examples that airdrops are no bad thing, ok almost every coin that has a airdrop fails but because the coin itself don't have any utility.
