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 users can't sell their tokens or if this isn't listed on coinmarketcap then is better to stay away from that airdrop because those are coins without value. Maybe in the future, those coins get a value, but that's a bet, maybe the coin never gets listed.
