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 you don't have time to investigate the web or the ANN Bounty/Airdrop developed in this Forum, you can visit here:
https://bitcointalk.org/index.php?board=83.0, every day, maybe you will find some Airdrops that you promote are scam or not.
The link I provided above can help you find out which Airdrop is a scam of at least 60%, and so on 40% more depending on you to consider and find out about the Airdrop that you are following a scam or not.
In general, half of the Airdrop journey is going, you will know a scam or not, based on what they show on ANN airdrop.
