How is Airdrop any different than the 10 dollar signup bonus on any non crypto w

[warriorcryptobar]

I seem to recieve the airdrop, and it immediately drops in value, I can't sell it, I can't move it. It's basically like a sign up bonus. I can't find one place that stores them all, so I can compound their worth. (coupon, limited one per). For being the early adopter in the trillion dollar emerging technologies, is the 10 dollar bonus really rewarding their early adopters? Or is it actually taking away from the time we could be earning fiat, and investing in a coin not being airdropped. Such as btc or eth.
