hello the community, i'm really curious, about all this Airdrop could someone tell me, how can you see when it's a scam Airdrop ? I mean i've seen so many Airdrops since i'm a member. Each Airdrop, i try to contact the administrateurs of each telegram. Some are just impossible to talk with someone professional. Looks like there are many scams or fake Airdrops. Thanks to help me to find a good airdrop

You can`t really tell for sure whether an airdrop is a scam or not, but I follow a few rules: never download and install a new wallet and never send money to project`s dev. And, of course,
never ever send your Private Key or Keystore File (UTC JSON), but I guess this have common sense for an intelligent person (surprisingly, I`ve heard that many persons do fill their Private Key into the registrations forms

). Also, setting up a new email address for registrations might be a smart move if you don`t want to risk having your personal email bombarded with spam.
