Inasmuch as the majority of airdrops turn out being scam I believe they are a few that are legit. But i don't think it's worth it when you will have to participate in 100 airdrops to find 1 that isn't scam or worthless.
Yeah i agree with you. Being scammed is very very very bad since you wont get what you're working for. Airdrops are a very good way to earn free coins but the only problem is their authenticity
