Anytime I go into my telegram account, I see countless number of airdrop with countless offers but the challenge is trying to know which of this airdrop that is genuine.
If airdrops are worth and real it will make some noise on bitcointalk and other social media so don't waste your time by claiming every airdrop you see on telegram because 99% of them will be fake ones.There is no one rule to find whether the airdrop is real or fake but if you have the analytical skills to evaluate a project then it will help you in finding the real airdrop as well.
That's probably true,
but the moment that we can see it on bitcointalk that the certain airdrop is being talked about, the airdrop is probably finished by that time. It only means that it is hard to know fake airdrops and legit ones.
If you are talking about UNI tokens airdrop, it is only announced after the timeline period ended so no one really knows that it was coming but now scammers take advantage of uniswap and trying to imitate the same with same name or replica of it.
