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.
95% of airdrops that happened in telegram didn't legit airdrop. The legit airdrop can be determined from the what project that has already made it. You can try to know the reputation of the team and project.
As long as the token or coin have already traded on the exchange site and that could be considered as legit airdrop.
Any airdrop have different rules to participated in.
Give your identity is not always making the airdrop become legit airdrop.
There are so many fake airdrop these days.
